Infertility due to diseased pelvic peritoneum: laparoscopic treatment.

Thirty-one patients complaining of unexplained infertility for at least 36 months and diagnosed elsewhere were reassessed laparoscopically. After staining their pelvic peritoneum with concentrated methylene blue, they presented with extensive areas of dark blue discoloration, and were diagnosed as suffering from 'diseased pelvic peritoneum'. The levels of peritoneal CA 125 were assessed. At the end of the diagnostic procedure, bipolar electrocoagulation or defocalized laser beam therapy was performed to destroy the affected peritoneal areas, and to allow peritoneal regeneration. Twenty-five pregnancies were obtained following this treatment. A detailed description is given of the diagnosis and treatment procedures.

Serous surface papillary carcinoma of the peritoneum: clinical, radiologic, and pathologic findings in 11 patients.

OBJECTIVE: The purpose of our study was to describe the clinical, radiologic, and pathologic findings of serous surface papillary carcinoma of the peritoneum in 11 patients. CONCLUSION: Serous surface papillary carcinoma of the peritoneum should be included in the differential diagnosis when ascites, omental caking, and peritoneal nodules or enhancement are observed in a postmenopausal woman with or without ovarian enlargement.

[Primary malignant schwannoma in peritoneum of pelvis minoris: a case report].

There are reports of rare cases of malignant schwannoma of the small bowel, ovary or urinary bladder. We report a case of malignant schwannoma found in peritoneum without any other localisation in 66-year-old woman. The first diagnosis was tumor of right ovary. Laparotomy was performed and a big, solid tumor of urinary bladder involving the small bowel was found. There were some small tumors in peritoneum and parametrium. All the tumors were removed. The histological changes of the small lesions were described as malignant schwannoma. The mass in urinary bladder and small bowel was found to be of an inflammatory origin. The cases described by other authors suggest, that the diagnosis of malignant schwannoma in pelvis minoris is very difficult. Surgery is an adequate way of final diagnosis and management.

[Lymph node and peritoneum metastases of bile duct cancer responding to chronochemotherapy--a case report].

A 68-year-old man underwent curative pancreaticoduodenectomy for bile duct cancer. The histological diagnosis was well differentiated, invasive type tubular adenocarcinoma, which was 2 x 2 cm in size and had invaded to the adventitia. Lymph node metastasis was not present. The postoperative course was uneventful, but lymph node and peritoneum metastases were detected 18 months after surgery. Chronochemotherapy of 5-FU (500 mg/body), leucovorin (21 mg/body), mitomycin C (2 mg/body) and cisplatin (80 mg/body) was performed without significant side effects. One course of chronochemotherapy was effective for lymph node and peritoneum metastases. The patient died of peritonitis carcinomatosa 10 months after recurrence.

Malignant fibrous histiocytoma of peritoneum presenting as intestinal obstruction.

Malignant fibrous histiocytoma (MFH) is a high-grade soft-tissue sarcoma of fibroblast-cell origin with a propensity for metastasis and recurrence. Primary MFH of the peritoneum is rare. We report a 60-year-old man with MFH of the peritoneum presenting with obstructive symptoms. Complete surgical excision of the tumor was done, and he is well six months later.

Primary papillary serous carcinoma of the peritoneum: a case of complete remission of bulky peritoneal disease after chemotherapy.

Peritoneal papillary serous carcinoma is a rare tumor that involves the surface of the pelvic and/or abdominal peritoneum. Long-term survival among patients with this tumor has been rare. Most patients with this cancer have been treated with debulking surgery and postoperative chemotherapy. A case of incompletely resected peritoneal papillary serous carcinoma with a complete response to cisplatin-based chemotherapy is reported. Subsequent laparotomy revealed no residual tumor. This case suggests that primary chemotherapy may be successful in treating unresectable primary papillary serous tumors of the peritoneum.

Serous carcinoma of the peritoneum after oophorectomy.

BACKGROUND: Prophylactic oophorectomy in premenopausal women has been recommended to prevent ovarian cancer. However, serous carcinoma of the peritoneum, which is indistinguishable from ovarian carcinoma, can occur after oophorectomy. CASES: Two cases are reported of serous carcinoma of the peritoneum after oophorectomy. Presentation, management, and outcome are similar to those for ovarian carcinoma. CONCLUSION: More data are needed to quantify the risk of carcinoma after oophorectomy. Such knowledge may change the risk-benefit calculations of recommending prophylactic oophorectomy to premenopausal women at a certain age, and must be discussed with the patient who is considering prophylactic oophorectomy with or without other planned surgery.

[Hepatic hydatid cyst ruptured in the peritoneum].

Romania is an endemic region for hydatid cyst and has a high incidence of hepatic hydatid cysts. If the intrabiliary rupture is the most frequent complication encountered, rupture in the peritoneum is rare, with exact data not available. Between 1993-2002 160 patients with hepatic hydatid cysts were operated. Six of them had an intraperitoneal ruptured cyst. Ultrasound raised the suspicion of hepatic hydatid cyst ruptured in the peritoneum in 4 cases, in one case the intact cyst migrated in the lower abdomen were it was mistaken for an ovarian cyst. After a thorough lavage with hypertonic serum, the parasite was evacuated, the pericyst partially removed and the cavity collapsed with non-absorbable sutures. The postoperative course was uneventful. Prophylaxis with benzimidazolic drugs started days 2-3 PO. At a follow-up between 1-4 years no peritoneal hydatidosis was detected. In the intraperitoneal ruptured hydatid cyst the hypertonic serum and benzimidazolic drugs can be useful in preventing peritoneal seedings.

Hematoma into peritoneum following transrectal echo-guide prostate biopsy inducing lower abdominal and urinary tract symptoms.

A 58 years man was submitted to a sextant echo-guided transrectal prostate biopsy. Three weeks later he started complaining of lower abdominal and urinary tract symptoms. Abdominal ultrasound and 3D contrast enhanced CT detected an ovular shaped and capsulated 140 cc volume mass into the peritoneum compressing the bladder. Cytology evaluation showed only haemorrhagic content. After the mass evacuation all the symptoms referred, disappeared. Anyway a hematoma into the peritoneum following a transrectal echo-guided prostate biopsy should represent a unique entity. In fact, this is considered a safe procedure in which generally mild complications occur and they stop spontaneously.

Malignant solitary fibrous tumor originating from the peritoneum and review of the literature.

BACKGROUND: Solitary fibrous tumor (SFT) is a rare neoplasm frequently involving the pleura. Benign and malignant forms of the tumor occur, the benign variant being three to four times more common than the malignant. CASE REPORT: We present herein a rare case of large malignant solitary fibrous tumor (SFT) originating from the peritoneum. An abdominal computed tomography scan revealed a well-defined solid tumor with mixed density. An abdominal ultrasonography (US) revealed a well-circumscribed solid tumor containing a partially cystic lesion. T1-weighted abdominal magnetic resonance imaging demonstrated a hypo- to isointensity, which was a hypo- to hyperintensity on T2-weighted images. Liposarcoma originating from the retroperitoneum was suggested, and the patient underwent a complete resection of the tumor as well as the left kidney because tumor invasion of the upper left kidney was suspected. Immunohistochemically, the spindle-shaped cells were positive for CD34, and the diagnosis was SFT originating from the peritoneum. At the 14-month follow-up evaluation, no recurrence or metastasis was detected. CONCLUSIONS: This case gave us some difficulty, and the correct diagnosis of the peritoneal mass was valuable. To diagnose the malignant potential of this type of tumor accurately may have value to direct the appropriate therapeutic operations after surgery and postoperative progress observation.

Benign multicystic mesothelial proliferation of the peritoneum: immunohistochemical and electron microscopical study of a case and review of the literature.

We report a case of benign multicystic mesothelial proliferation (the so-called multicystic peritoneal mesothelioma) arising multifocally in the abdomen of a 46-year-old white man. His anamnesis showed an 8-year history of intermittent pain in the right lower abdominal quadrant. Mucin stains, immunohistochemistry, and electron microscopy confirmed the mesothelial origin of the lesion. Review of the available literature allowed us to find another 85 reported cases of benign multicystic mesothelial proliferations of the peritoneum. Out of these cases, eighteen only occurred in men, the majority being reported in middle-aged women mostly with complaints of abdominal pain. Electron microscopy or immunohistochemistry are needed to make a differential diagnosis towards other multicystic lesions, such as peritoneal cystic lymphangioma. Although multicystic mesothelial proliferations of the peritoneum have often been regarded as benign neoplasms, the true nature--neoplastic or hyperplastic--of these lesions still remains greatly elusive. Therefore, we believe that the unbinding term benign multicystic mesothelial proliferation (first used with regard to the unique hitherto reported case arisen in the pleural cavity) should be considered at present more appropriate to indicate even these peritoneal lesions.

[Electron microscopic study of mesothelial cells in the diaphragm peritoneum of human fetus using the freeze-fracture replica method].

Electron microscopy of mesothelial cells from the diaphragm peritoneum of human fetuses was conducted using the freeze-fracture replica method. The results were as follows: 1) Numerous vesicles were found in single or cluster forms. The latter type was often fused with large vacuoles and opened to the free surface of the cell as secretory granules. 2) On the fractured faces of plasma and nuclear membranes, different numbers of intramembraneous particles and exocytic pores were seen on the PF surface of the plasma membrane. The diameter of the exocytic pores averaged 43 nm, and their maximum number was 26/microns2. 3) Neighboring cells were conjoined by cytoplasmic processes which were seemed to form three-dimensional intertwinings. 4) The microvilli of the mesothelial cells were grouped into three morphological classes, i.e. fork-like microvilli, bulbous ending microvilli, and stick-like microvilli. In addition, the contrast between the present investigation and the results of fine section studies on the diaphragm peritoneum of human fetus is discussed.

Benign cystic mesothelioma of the peritoneum: report of a case.

A 36-year-old multiparous woman presented with the chief complaint of mass and fullness over the lower abdomen for the previous 3 months. Abdominal ultrasound revealed a uniloculated, thin-walled cyst attached to the peritoneal surface of the right lower abdomen. The cyst was surgically excised and confirmed to be cystic mesothelioma of the peritoneum by histopathologic and immunohistochemical studies. Benign cystic mesothelioma is an extremely rare intraperitoneal tumor. Although its etiology remains unclear, one distinctive clinicopathologic feature is a symptomatic abdominal mass in young females. The presence of a thin-walled cyst attached to the peritoneum on ultrasound should alert physicians to the possibility of this disease. The treatment of choice is complete resection and reexcision may be required due to a preponderance for local recurrence. Regular postoperative ultrasound follow-up is recommended to check for possible recurrence.

Papillary serous carcinoma of the peritoneum.

Between January 1, 1970, and December 31, 1983, 817 patients with serous ovarian carcinoma were seen at M. D. Anderson Cancer Center. Within this population, we identified those patients with normal-sized ovaries (4 cm or less in maximum diameter) and those with papillary serous histology, exclusive of borderline tumors. The 74 patients so identified were classified as having papillary serous carcinoma of the peritoneum, and form the basis of this report. The average age at diagnosis was 57.4 years. The majority of the patients (90.5%) were white. Common presenting symptoms included abdominal pain (54.9%) and abdominal distention (51.5%). In 89.1% of patients, disease involved the omentum. Clinical response to chemotherapy was seen in 63.6% of the patients; 40.9% of them had partial responses and 22.7% complete responses. At second-look laparotomy, 27.3% of 33 patients demonstrated a surgical complete response, 21.2% had microscopically positive disease only, and 51.1% had grossly positive disease. The median survival for the total group was 24.0 months. Neither patient age nor presence of residual disease after cytoreduction predicted survival. Patients treated with combination chemotherapy fared better than patients treated with single-agent regimens (29.5 versus 16.5 months; P = .01). Patients receiving cisplatin-containing regimens also did better (31.5 versus 19.5 months; P = .02). Among several pathologic characteristics analyzed, only the absence of mitoses predicted improved survival (76.5 versus 21.4-27.0 months; P less than or equal to .05). Papillary serous carcinoma of the peritoneum, though biologically and histologically similar to ovarian carcinoma, is a distinct clinicopathologic entity not uncommonly encountered by the gynecologist.

Differential L chain expression in the antibody responses to phosphorylcholine of adult bone marrow or peritoneum-derived B lymphocytes.

Lethal irradiation of adult BALB/c mice followed by reconstitution with autologous bone marrow results in loss of T15 Id and IdX expression in the responses to phosphorylcholine (PC) and alpha(1-3)-dextran, respectively. T15 Id, but not IdX expression can be reconstituted with low numbers of syngeneic, T cell-depleted peritoneal resident cells. All three groups of mice produce comparable titers of specific anti-PC and anti-dextran antibodies. The inability of adult bone marrow-reconstituted BALB/c mice to produce T15 Id+ antibodies is not due to differential VH-gene expression in bone marrow or peritoneum-derived B cells. Thus, the levels of T15 VH in total serum Ig and in anti-PC antibodies are similar in all groups of mice. Furthermore, IEF patterns of T15 VH-associated L chains directly demonstrate differential Vk repertoire expression in bone marrow and peritoneum-derived B cells.

Malignant mixed mesodermal tumour of the peritoneum with a complete response to cyclophosphamide.

We treated a 66-year-old Japanese woman with malignant mixed mesodermal tumour of the heterologous type arising from the paracolic peritoneum. The tumour contained heterologous elements in the form of cartilage in addition to carcinosarcomatous areas. This is the third case of malignant mixed mesodermal tumours originating from the peritoneum to be documented in the literature. A complete resection of the tumour was carried out but multiple lymph nodes metastases in the left neck occurred 5 months later. Cyclophosphamide in doses of 150 mg daily by mouth was initiated, with the result of a complete regression of the malignant lesions. She died of myocardial infarction 21 months after surgery.

[A case of barium-peritoneum with neurological involvement. Importance of barium determination in biological fluids].

Barium in the peritoneum following a barium enema led to a severe and irreversible chronic barium poisoning, although from the abdominal and gastro-intestinal point of view, there were virtually no sequelae. Barium assay on the cerebro-spinal fluid of this patient revealed excessively high levels, which provides the laboratory evidence of the direct action of barium on the central nervous system. Barium assays on biological fluids after barium-peritoneum could be used to assess the degree of barium poisoning and may have prognostic value.

[Malignant mesothelioma of the peritoneum].

An observation of malignant peritoneal mesothelioma in a man of 61 is presented. The clinical signs included fatigue, loss of weight, enlarged abdomen. The duration of the disease was 8 months. The autopsy revealed a whitish tumor of the peritoneum of cartilage density with numerous nodules 0.5-1.5 cm in diameter. The tumor overgrew the liver, spleen, pancreatic gland, stomach, and intestinal loops forming a single conglomerate. In the peritoneal cavity there were 4000 ml of transparent yellowish fluid. The visceral and parietal pleura on the left was thicker and covered with small whitish nodules. Histological examinations showed the peritoneum to be thickened, sclerosed and hyalinized. In the thickness of the fibrous stroma there were numerous slits lined with mesothelial cells. There were metastases in regional lymph nodes. The tumor had the structure of a malignant mesothelioma of the epithelial-like variant.
