Primary fallopian tube carcinoma. Histopathology of 46 cases.

Here we report on histopathological findings from 46 cases of primary Fallopian tube carcinoma (PFTC) which were diagnosed and/or consulted in the Department of Pathology, University Medical School of Wrocław between 1982 and 1997. PFTCs can be classified according to the WHO International Classification of Ovarian Tumors. Reexamination of glass slides revealed at least five histological types of PFTC. Our results indicated better prognosis in patients with primary Fallopian tube endometrioid carcinoma rather than with serous carcinoma. Patients with PFTC expressing urothelial differentiation also show better prognosis. These findings confirm greater usefulness of primary ovarian carcinoma classification in the evaluation of the primary salpingeal carcinomas. The problems encountered in diagnosis, prognosis and therapy of PFTC are discussed.

Neisseria gonorrhoeae mutants altered in toxicity to human fallopian tubes and molecular characterization of the genetic locus involved.

In an effort to identify potential cytotoxins expressed by Neisseria gonorrhoeae, we have identified a locus that, when mutated in the gonococcus, results in a significant increase in toxicity of the strain to human fallopian tube organ cultures (HFTOC). This locus, gly1, contains two open reading frames (ORFs) which are likely cotranscribed. ORF1 encodes a polypeptide of 17.8 kDa with a signal sequence that is recognized and processed in Escherichia coli and N. gonorrhoeae. The 15.6-kDa processed polypeptide has been observed in membrane fractions and filtered spent media from cultures of E. coli expressing gly1 and in outer membrane preparations of wild-type N. gonorrhoeae. The gly1 locus is not essential for bacterial survival, and it does not play a detectable role in epithelial cell adhesion, invasion, or intracellular survival. However, a gly1 null mutant causes much more damage to fallopian tube tissues than its isogenic wild-type parent. A strain complemented in trans for the gly1 mutation showed a level of toxicity to HFTOC similar to the level elicited by the wild-type parent. Taken together, these results indicate an involvement of the gly1 locus in the toxicity of N. gonorrhoeae to human fallopian tubes.

Penetration of lymecycline (tetracycline) into the tissues of the Fallopian tube.

On the basis of a comparison of different methods used to determine the concentration of active lymecycline in Fallopian tube tissue, a method was adopted which allowed the determination of lymecycline in serosa and mucosa tissue of the Fallopian tube in 16 women undergoing hysterectomy. A difference in the concentration of active drug was found in serosa (greater than 1.7 mg/kg tissue) and mucosa (greater than 0.8 mg/kg tissue) in 16 patients on lymecycline therapy for 24 hours. These figures were fairly constant for the 7.5 hours following the administration. The figures are discussed in relation to the MIC values of the commonly found microorganisms in salpingitis.

Human fallopian tube expresses transforming growth factor (TGF beta) isoforms, TGF beta type I-III receptor messenger ribonucleic acid and protein, and contains [125I]TGF beta-binding sites.

Reverse transcription-polymerase chain reaction analysis of total ribonucleic acid (RNA) from human fallopian tubes revealed that transforming growth factor-beta 1 (TGF beta 1), TGF beta 2, and TGF beta 3 as well as TGF beta type I-III messenger RNA (mRNA) are expressed in this tissue. In situ hybridization and immunohistochemical observations using TGF beta isoform-specific [35S]40-mer oligonucleotide probes and polyclonal antibodies indicate that all the tubal cell types express TGF beta isoforms and TGF beta type II receptor mRNA and protein. The tubal epithelial cells appeared to express more TGF beta 1 mRNA and TGF beta 1-3 proteins than other cell types, whereas TGF beta 2 and TGF beta 3 mRNA appeared to be equally expressed in the epithelial and other tubal cell types. In the epithelial lining, both ciliated and nonciliated cells in the ampullary and isthmus regions appeared to express mRNA and protein for TGF beta s and TGF beta type II receptor at a similar level. The intensity of immunostaining of TGF beta s in tubal epithelial cells was lower during the early proliferative and late secretory than the mid- to late proliferative and early to midsecretory phases of the menstrual cycle and reduced during the postmenopausal period. However, the intensity of immunoreactive TGF beta type II receptor in these cells did not vary during the cycle as much as that seen with TGF beta s. Quantitative autoradiography of [125I]TGF beta 1 indicates that fallopian tubes contain specific binding sites for TGF beta 1. Net grain density per 100 microns 2, calculated for different cell types, indicates that the epithelial cells had a significantly higher grain density than other tubal cell types (P < 0.05), with similar densities in the late proliferative and early secretory phases of the cycle. These results provide the first evidence that human fallopian tubes express mRNA and protein and contain specific binding sites for TGF beta system, suggesting an autocrine/paracrine role for TGF beta in a variety of tubal functions.

Early adenocarcinoma of the fallopian tubes. A case for multifocal tumorigenesis.

Seven cases of carcinoma in situ and/or early invasive carcinoma of the fallopian tube found in association with serous carcinoma of the ovary are described. These cases are considered to represent examples of multicentric tumorigenesis in Müllerian epithelia which have a common origin and have responded to a common carcinogenic influence. Early neoplastic lesions of the tube may be overlooked unless the tube is serially blocked. If this is done, such lesions may be expected in 5-10% of patients with serous carcinoma of the ovary. Criteria for diagnosis of carcinoma in situ are discussed, viz., a noninvasive proliferative epithelial lesion with disorganization of cellular relationships, significant mitotic activity and nuclear atypia (especially prominence of nucleoli). Criteria for diagnosis of invasive carcinoma of fallopian tube are also referred to particularly with respect to establishing a primary site of tumor origin in cases where masses are present in both ovaries and tubes.

Pseudocarcinomatous hyperplasia of the fallopian tube associated with salpingitis. A report of 14 cases.

We describe 14 cases of pseudocarcinomatous changes in the fallopian tube characterized by florid epithelial hyperplasia and in half the cases mesothelial hyperplasia and associated with chronic salpingitis. The patients' ages ranged from 17 to 40 years. Seven had clinical evidence of pelvic inflammatory disease. Tubal enlargement or thickening were observed in 12 cases and pyosalpinx, tubo-ovarian abscesses, or hydrosalpinx, in six cases. All cases showed no gross evidence of tumor. The reactive atypical hyperplasia mimicked carcinoma microscopically because of a cribriform pattern, penetration of the tubal wall by hyperplastic epithelium, florid mesothelial hyperplasia, or a combination of these findings; epithelial papillae were present in the lymphatics in two cases. In five cases, an erroneous microscopic diagnosis of carcinoma had been made or seriously entertained initially, and one patient underwent a radical hysterectomy as a result. The typically young age of the patients, absence of a gross tumor, presence of severe chronic inflammation, lack of solid epithelial proliferation, mildness of nuclear atypia, and paucity of mitotic figures facilitated the differential diagnosis. Nine patients for whom follow-up information was available had no recurrence of tubal disease.

Liver metastasis as a first sign of fallopian tube carcinoma and the role of positron emission tomography in preoperative diagnosis.

The search for an unknown primary tumour is often time-consuming, costly and unrewarding. Positron emission tomography might be an effective method for screening the body for malignant deposits. We present the case of a woman with a symptomatic liver tumour of unknown origin. Several investigations did not reveal a primary tumour, but PET scanning showed a hot spot in the pelvis, suggesting either a primary tumour or a metastatic deposit. During operation, a primary Fallopian tube carcinoma was detected. Histopathological examination of the resected liver tumour revealed a metastasis of the Fallopian tube carcinoma. This case report demonstrates that PET scanning can be useful in the diagnostic process in patients with unknown primary tumour, and that a symptomatic liver tumour can be the first sign of Fallopian tube carcinoma.

Fallopian tube cancer: incidence and role of lymphatic spread.

Lymphatic spread pattern in 17 cases of adenocarcinoma of fallopian tube is reported. Median age of the patients was 48 years. All patients underwent surgical staging including total abdominal hysterectomy, bilateral salpingo-oopherectomy omentectomy, and appendectomy. Systematic pelvic and paraaortic lymphadenectomy was feasible in 15 cases. Majority of the patients (11 of 17 cases, 64%) had advanced disease and showed serous adenocarcinoma (83%). Lymph nodes were involved in 10 of 17 cases (59%). Node metastases rate increased significantly (P < 0.01) with intraperitoneal stage of disease and with grading. Interestingly, positive nodes were also found in 2 cases (33%) of 6 patients with disease still limited to fallopian tube. Overall, patients with negative nodes had a median survival of 76 months, compared with only 33 months if node metastases were found. In conclusion, combined pelvic and para-aortic lymphadenectomy seems to be necessary for staging and perhaps for prognosis of this disease.

Scanning and transmission electron microscopy of bacterial attachment to mucosal surfaces with particular reference to the human fallopian tube.

Neisseria gonorrhoeae and Chlamydia trachomatis are the common bacteria isolated from bacterial cervicitis and are the leading etiological agents for pelvic inflammatory disease. Neisseria gonorrhoeae cause infection of the mucosa of fallopian tubes in organ culture by attaching to microvilli of nonciliated cells, phagocytosis by these cells, transport across and exocytosis from the epithelial cells. In contrast the Chlamydia attach to the epithelial surface without apparent ligand binding and are taken into the cytoplasm of the epithelial cell. Exocytosis of Chlamydia is into the tubal lumen and not into the subepithelial spaces. The ciliated epithelial cells of the fallopian tube are damaged by a gonococcal toxin but chlamydia do not exhibit such activity. These observations suggest that the mechanism of attachment to and invasion of the mucosal epithelium by gonococci and chlamydia are quite different and their potential for disease production occurs by different methods.

[Association of fallopian tube cancer and polymyositis. Apropos of 1 case].

A 51-year-old woman consulted for pelvic pain, metrorrhagia and leukorrhea. Physical examination revealed a renitent and mobile mass in the pelvis. A right lateral uterine mass with hydroxalpinx was found at ultrasonography. Pathology examination of the right annexectomy specimen provided the definitive diagnosis: fallopian tube cancer with polymyositis. No residual tumor was found at total hysterectomy with total bilateral annexectomy. The patient was lost to follow-up for three years without complementary treatment then consulted later for functional disability of the upper then lower limbs with myalgia, swallowing disorders and left supraclavian node enlargement resulting from pelvic relapse of the right fallopian tube adenocarcinoma and left supraclavian metastasis with paraneoplastic polymositis. The patient was given 6 courses of chemotherapy with radiotherapy (45 Gy) centered on the left clavian region. The patient exhibited a spectacular response, and remains in complete remission 50 months after diagnosis. The association of a fallopian tube tumor with polymyositis is exceptional, requiring rapid anticancer treatment effective against the cancer and the paraneoplastic polymyositis.

Fallopian tube recanalization in an unrestricted patient population.

PURPOSE: To review the effectiveness of fallopian tube recanalization (FTR) when performed without restriction based on history or tubal condition. MATERIALS AND METHODS: From October 1989 to July 1992 in 37 consecutive women, aged 22-44 years (mean, 35 years), 42 FTRs were performed (five patients each underwent two FTRs). Water-soluble contrast material and selective ostial salpingography and/or microcatheter technique were used exclusively. Eighty tubes were evaluated, since four patients had previously undergone unilateral salpingectomy. Sixty-three tubes (79%) were occluded at the outset of the procedure. RESULTS: Complete recanalization was achieved in 45 of 63 (71%) occlusions. Adhesions were present in 25 of 80 (31%) tubes, salpingitis isthmica nodosa in 12 (15%), and hydrosalpinx in nine (11%). The 42 procedures resulted in 14 (33%) conceptions, nine (64%) of which involved pathologic tubes. Eleven intrauterine pregnancies resulted in five spontaneous first-trimester abortions, five full-term deliveries, and one continuing pregnancy. CONCLUSION: Favorable conception and live birth rates can be achieved with FTR, despite a high prevalence of tubal disease.

A comparative morphological and ultrastructural study of endometrial gland and fallopian tube epithelia at different stages of the menstrual cycle and the menopause.

Cyclical ultrastructural changes in the endometrium and Fallopian tube have been reported previously but in different subjects. The aim of this study is to compare cyclical changes in endometrial gland and tubal (isthmic, mid-tube, ampulla, and fimbria) epithelia in the same subjects with a view to identifying any similarities or differences which may have clinical implications for assisted reproduction treatment. Endometrial and Fallopian tube samples were obtained from women undergoing hysterectomy and salpingectomy. We report similar epithelial surface changes taking place in the endometrial glandular and endosalpingeal epithelia with the exception of the fimbriae. Secretions within endometrial gland lumen and the isthmus increase throughout the late follicular phase and before ovulation, then dissipate in these two regions simultaneously in the early/mid luteal phase. Similarly, in the late follicular and pre-ovulatory phases, the process of granule secretion is similar in the glandular epithelium, isthmus and ampulla. In the fimbriae, no comparable activity is noted during these phases of the menstrual cycle. The differences reflect the functional differentiation between these regions. Equally, the observed similarities highlight the need for further comparative studies to determine the role of these secretions in early embryonic development and their clinical relevance.

Malignant mixed mullerian tumors of the fallopian tube.

Malignant mixed mullerian tumors of the female genital tract are rare and occur least commonly in the fallopian tube. A case is reported and 51 other cases in the literature are reviewed. The mean age at diagnosis is 59 years. Abdominal pain is the most common presenting complaint. A pelvic or abdominal mass is present in 75% of patients. The diagnosis is not usually established until surgery, with the most common preoperative diagnosis being ovarian malignancy. Seventy-five percent of cases had tumor extension beyond the fallopian tube at the time of surgery. Treatment has focused on surgery with postoperative radiation and/or chemotherapy. Prognosis is poor, with fewer than half of patients surviving 2 years. Recent reports suggest improved outcome with platinum-based chemotherapy but data are limited.

Nuclear progesterone receptor A and B isoforms in mouse fallopian tube and uterus: implications for expression, regulation, and cellular function.

Progesterone and its interaction with nuclear progesterone receptors (PR) PR-A and PR-B play a critical role in the regulation of female reproductive function in all mammals. However, our knowledge of the regulation and possible cellular function of PR protein isoforms in the fallopian tube and uterus in vivo is still very limited. In the present study, we revealed that equine chorionic gonadotropin (eCG) treatment resulted in a time-dependent increase in expression of both isoforms, reaching a maximal level at 48 h in the fallopian tube. Regulation of PR-A protein expression paralleled that of PR-B protein expression. However, in the uterus PR-B protein levels increased and peaked earlier than PR-A protein levels after eCG treatment. With prolonged exposure to eCG, PR-B protein levels decreased, whereas PR-A protein levels continued to increase. Furthermore, subsequent treatment with human (h)CG decreased the levels of PR protein isoforms in both tissues in parallel with increased endogenous serum progesterone levels. To further elucidate whether progesterone regulates PR protein isoforms, we demonstrated that a time-dependent treatment with progesterone (P(4)) decreased the expression of PR protein isoforms in both tissues, whereas decreases in p27, cyclin D(2), and proliferating cell nuclear antigen protein levels were observed only in the uterus. To define the potential PR-mediated effects on apoptosis, we demonstrated that the PR antagonist treatment increased the levels of PR protein isoforms, induced mitochondrial-associated apoptosis, and decreased in epidermal growth factor (EGF) and EGF receptor protein expression in both tissues. Interestingly, immunohistochemistry indicated that the induction of apoptosis by PR antagonists was predominant in the epithelium, whereas increase in PR protein expression was observed in stromal cells of both tissues. Taken together, these observations suggest that 1) the tissue-specific and hormonal regulation of PR isoform expression in mouse fallopian tube and uterus, where they are potentially involved in regulation of mitochondrial-mediated apoptosis depending on the cellular compartment; and 2) a possible interaction between functional PR protein and growth factor signaling may have a coordinated role for regulating apoptotic process in both tissues in vivo.

Fallopian tube carcinoma: incidental finding during surgery for acute pelvic inflammatory disease--case report.

BACKGROUND: Primary carcinoma of the fallopian tube is a rare condition. Preoperative diagnosis is difficult and in most cases it is an intraoperative finding or a histopathological diagnosis. CASE: A 49-year-old woman presented with pelvic pain, fever (38 degrees C), elevated white blood cell count and a right adnexal mass. Pelvic inflammatory disease was suspected and broad spectrum antibiotics were established. Five days later, due to lack of clinical response, a total abdominal hysterectomy, bilateral salpingo-oophorectomy and appendectomy were performed. Histopathology showed a primary fallopian tube carcinoma. Postoperatively she received chemotherapy. Afterwards she underwent a staging laparotomy. Some months later, new chemotherapy regimens were instituted because of the presence of lymph node metastases. CONCLUSION: Malignancy should be included in the differential diagnosis of pelvic inflammatory disease.

Congenital or torsion-induced absence of Fallopian tubes. Two case reports.

Unilateral absence of a uterine tube is an extremely rare finding, for which there are two possible etiopathogenic causes: in some cases it is due to haemorrhage filling of the cavity and its reabsorption as a result of asymptomatic torsion of the uterine tube during adult life, in pediatric age or even during intrauterine life; alternatively, the absence may be congenital, associated with developmental alterations of the mesonephric and paramesonephric ducts. The article presents two cases of fallopian tube absence: a congenital monolateral absence and a tubal torsion during pregnancy. The symptomatology of the torsion of the fallopian tube in pregnancy can be milder than in the classic description with peritoneal reaction and severe clinical alteration. The main risk factors for tubal torsion are: adhesions and inflammatory processes, ovarian cysts, usually of dermoid type, menstrual period, pregnancy, abnormal long mesosalpinx and/or mesovarium, pelvic congestion induced by constipation and disturbed venous blood flow from the adnexa. A congenital defect of the mesonephric duct is followed by a homolateral defect of the paramesonephric duct. The resulting anomaly is characterized by the absence of the uterine tube, uterus-tube angle, kidney and ureter. Partial or total unilateral defects of a paramesonephric duct are more common than aplasia of both ducts. Some authors have suggested that an inadequate blood supply during the descent into the pelvis of the caudal part of the paramesonephric duct might feasibly lead to incomplete tube development.
