Sciatic neuropathy secondary to a uterine fibroid: a case report.

Lesions of the sciatic nerve outside the pelvis have been well described. Lesions within the pelvis, however, are far less common. We report the case of a 55-yr-old woman with a history of chronic low back pain who presented with progressive right buttock and posterolateral right lower limb pain associated with right foot numbness and tingling. She denied any associated low back or left lower limb pain. The patient was initially treated for a probable right lumbosacral radiculopathy, without improvement. A subsequent magnetic resonance image of the lumbosacral spine revealed multilevel disc degeneration at L3-4 through L5-S1, without disc herniation or canal stenosis. A magnetic resonance image of the pelvis revealed a markedly enlarged uterus, with a large pedunculated myoma impinging on the right sciatic foramen. The patient underwent a subtotal abdominal hysterectomy, with resolution of her right lower limb pain. This case illustrates the importance of considering intrapelvic causes of sciatic neuropathy. To our knowledge, this is the first reported case of sciatic neuropathy secondary to a uterine fibroid.

Inflammatory fibroid polyp of the stomach. Report of three unusual cases.

Three patients with inflammatory fibroid polyp (IFP) of the stomach underwent operation with a diagnosis of submucosal tumor, polyp, and intramural tumor of the stomach, respectively. Resected specimens grossly showed a deep ulcer accompanied by surrounding upheaval, a sausagelike polyp 6.5 cm long, and a pedunculated tumor with a short pedicle, respectively. Histologic examination showed that each lesion was typical of IFP of the stomach, with a mixture of fibroblasts and thin-walled blood vessels, and further by an intense infiltrate of eosinophils. These cases indicate that IFP of the stomach can vary in gross appearance. Practitioners and pathologists must remember that not only a polypoid lesion, but also a pedunculated or even ulcerated lesion, in the gastric antrum may be IFP.

Symptomatic inflammatory fibroid polyp of the small bowel: report of two cases with review of literature.

Two cases of symptomatic inflammatory fibroid polyps (IFP) of the small intestine are presented, and the 17 adequately described symptomatic IFP previously reported are reviewed. IFP of the small bowel are rare. Most patients present with intestinal obstruction and a few with chronic anemia. IFP have characteristic histologic features and are easily recognized if they are considered in differential diagnosis.

Expression of CD34, bcl-2, and kit in inflammatory fibroid polyps of the gastrointestinal tract.

The histogenesis of inflammatory fibroid polyps (IFP) of the gastrointestinal tract, focused on the cell of origin of the stromal cells, is a controversial subject. The reported CD34 reactivity in gastric IFP has implied a histogenetic relationship with a variety of CD34-reactive tumors, including gastrointestinal stromal tumors (GIST). In addition to bcl-2, the majority of GIST has expressed Kit, suggesting an origin in interstitial cells of Cajal (ICC), which are selectively localized around nerve plexuses. Gastric (12) and colonic (two) IFP from 13 patients were studied, using antibodies against CD34, bcl-2, and Kit. IFP expanded muscularis mucosae with prominent vascular channels, inflammatory infiltrates, proliferating stromal cells, and extracellular matrix material. Eleven gastric IFP exhibited concentric stromal proliferations (CP), particularly, around vessels, glands, and muscle bundles. Their stromal cells were CD34 reactive, bcl-2 nonreactive, and Kit nonreactive and showed fibroblast-like appearances with thin, long cytoplasmic processes. In contrast, one gastric and two colonic IFP showed no CP, and their stromal cells were CD34 nonreactive, bcl-2 nonreactive, and Kit nonreactive. IFP with CP may have a different histogenesis from IFP without CP. IFP with CP may originate from a subpopulation of dendritic interstitial cells other than ICC, predominantly localized around blood vessels and muscle fibers in muscularis mucosae of the stomach.

Inflammatory fibroid polyps of the gastrointestinal tract: clinical, pathologic, and molecular characteristics.

Inflammatory fibroid polyp (IFP) of the gastrointestinal tract is an uncommon proliferative lesion. When sampled by biopsy, IFP can be mistaken for various lesions, from granulation tissue to high-grade sarcoma. We present an unusual case of IFP and review a large series of IFPs to characterize clinical, histologic, and molecular features of diagnostic value. A total of 42 IFPs were gathered from the pathology archives of the University of Pittsburgh Medical Center over the past 22 years. Clinical, histopathologic, and immunohistochemical features were collected. A random subset of IFPs (n = 12) underwent microdissection genotyping for a broad panel of tumor suppressor gene-associated mutations (loss of heterozygosity). IFPs occurred in both sexes (male, 17; female, 25) over a broad age range (29-85 years). IFPs varied in size from 0.2 to 8 cm. The stomach (n = 19) was the most common location, followed by large bowel (n = 13) and small bowel (n = 10). Most IFPs displayed typical morphologic features (eosinophils admixed with loose, mature fibrous tissue), and in 2 instances, sampled by biopsy, IFP was confused for sarcoma. All IFPs lacked c-kit staining. No mutations were identified in any IFPs examined. IFP is a clinically underrecognized entity with unique morphologic and immunohistochemical features. On biopsy alone, the differential diagnosis may include sarcoma and other malignancies. The absence of mutational change may help to exclude malignant lesions.

Myolysis of uterine fibroids: is there a role?

Myolysis is among the new procedures under development for the treatment of symptoms related to uterine leiomyoma. The procedure targets the destruction of fibroids using one of a number of focused energy delivery systems including those based upon radiofrequency electricity, supercooled cryoprobes, and, most recently, focused ultrasound monitored by real time magnetic resonance imaging. For thermomyolysis and cryomyolysis, delivery of the energy requires access to the tissue by laparoscopy, and, in some instances, hysteroscopy. For focused ultrasound, the patient is detached from the energy source, which is delivered by an array of external beams. Clinical evaluation has been confined to case series, but it is evident that the approach results in a variable degree of reduction of the total uterine mass, and, usually, a reduction in uterine bleeding. Clearly, longer term appropriately designed comparative trials are required that evaluate and compare myolysis with myomectomy, uterine artery embolization, and hysterectomy, to name a few.

Changing trends in gynecologists' opinions of uterine artery embolization for fibroids: the patient's perspective.

This study's purpose was to survey patients' perceptions of gynecologists' opinions of uterine artery embolization (UAE) for fibroids. Twenty-one women who underwent UAE between July 2000 and April 2002 and 21 women who underwent UAE between September 1998 and July 2000 completed questionnaires. Each woman was asked what her gynecologist's initial opinion was toward UAE, what treatment options were offered, who initiated discussion of UAE, and whether she returned to the same gynecologist after UAE. As of 2002, more gynecologists had a favorable opinion of UAE and were offering UAE versus in the year 2000. The majority of patients whose gynecologists initially opposed UAE did not return to the same gynecologists, reflecting a similar trend noted 2 years earlier.

Annular phased-array high-intensity focused ultrasound device for image-guided therapy of uterine fibroids.

An ultrasound (US), image-guided high-intensity focused ultrasound (HIFU) device was developed for noninvasive ablation of uterine fibroids. The HIFU device was an annular phased array, with a focal depth range of 30-60 mm, a natural focus of 50 mm, and a resonant frequency of 3 MHz. The in-house control software was developed to operate the HIFU electronics drive system for inducing tissue coagulation at different distances from the array. A novel imaging algorithm was developed to minimize the HIFU-induced noise in the US images. The device was able to produce lesions in bovine serum albumin-embedded polyacrylamide gels and excised pig liver. The lesions could be seen on the US images as hyperechoic regions. Depths ranging from 30 to 60 mm were sonicated at acoustic intensities of 4100 and 6100 W/cm2 for 15 s each, with the latter producing average lesion volumes at least 63% larger than the former. Tissue sonication patterns that began distal to the transducer produced longer lesions than those that began proximally. The variation in lesion dimensions indicates the possible development of HIFU protocols that increase HIFU throughput and shorten tumor treatment times.

Surgical and radiological management of uterine fibroids--a UK survey of current consultant practice.

BACKGROUND: The aim of this study was to determine the current surgical and radiological management of uterine fibroids by consultants working in the UK. METHODS: A structured questionnaire was posted to all 1439 UK consultants. Non-responders were sent one reminder. The main outcome measures were surgical route and technique used for myomectomy, and the use and availability of uterine artery embolization (UAE). RESULTS: Eight hundred fifty-two (59%) consultants replied. Seven hundred thirty-five (86%) admitted to regular sessions of gynecologic surgery, and 75% of this group performed open myomectomy, 16% laparoscopic myomectomy, and 66% hysteroscopic myomectomy. Open myomectomy: Forty-one percent of consultants performed open surgery on uteri equivalent to 12-week gestational age or less, 87% prescribed preoperative gonadotrophin-releasing hormone agonists (GnRHa) in order to reduce surgical bleeding, with 35% using myomectomy clamps, 23% tourniquets, and 19% vasoconstrictors. Laparoscopic myomectomy: The largest uterine size the majority would attempt was equivalent to a 12-week gestation, 58.6% used preoperative GnRHa, 21% used intraoperative vasoconstrictors, and 1.4% tourniquets in order to minimize bleeding. Hysteroscopic myomectomy: As with laparoscopic myomectomy, the largest uterine size the majority would attempt was equivalent to a 12-week pregnancy. Blood transfusion: Twenty per cent, 10%, and 7% reported the need for blood transfusion in up to 10% of patients undergoing open, laparoscopic, or hysteroscopic myomectomy, respectively. UAE: Fifty-one percent have access to UAE and 40% have referred at least one patient in 2001. CONCLUSIONS: Open and hysteroscopic myomectomy are frequently utilized in contrast to laparoscopic myomectomy. The reported rate of blood transfusion appears low. Although UAE is widely available, the majority of patients are still managed surgically.

An ultrastructural study of a jejunal inflammatory fibroid polyp.

Ultrastructural appearances of a small intestinal inflammatory fibroid polyp are reported. There is a vascular scaffolding, with interstices which contain regular and fibrous long-spacing type collagen, condensed lamellar basement membrane fibroblasts, basophils, some eosinophils and histiocytes. In addition other cells less easily characterized but believed to be of an endothelial and primitive mesenchymal cell nature are recognized. Possible origins of the polyp are considered.

Transcatheter uterine artery embolisation to treat large uterine fibroids.

Bilateral uterine artery embolisation was performed to treat eight women with symptomatic large fibroids requiring treatment. Uterine volume was quantitatively assessed by magnetic resonance imaging. Both uterine arteries were occluded effectively in all women, and the procedure was well tolerated, with a 24-36 hour admission for pain relief. The level of pain experienced was variable, but well controlled. Some women experienced intermittent vaginal discharge and pain following the procedure. Improvement of symptoms occurred in six of the seven women and the eighth woman conceived. There were no significant complications. At three months four women had a uterine volume of < 350 cm3. Embolisation appears to be a good alternative to surgery, but longer follow up is required to evaluate the long term effects and to determine those patients for whom the procedure is suitable.

Pregnancy following uterine artery embolisation for symptomatic fibroids: a series of 26 completed pregnancies.

OBJECTIVES: To evaluate the outcome of pregnancies after uterine artery embolisation for uterine fibroids. DESIGN: Retrospective analysis of pregnancy subsequent to uterine artery embolisation by one interventional radiologist. SETTING: A UK District General Hospital. POPULATION: Twenty-nine pregnancies in 671 women who had undergone uterine artery embolisation. METHODS: Cases were identified by screening questionnaire and from the study database. Detailed information was collected by questionnaires, direct conversations with women and, when necessary, from hospital records. MAIN OUTCOME MEASURES: Pregnancy outcome, complications and neonatal outcomes. RESULTS: Of 26 completed pregnancies, detailed information was available for 24 and limited information for 2. Seven (27%) ended in miscarriage, there were two terminations and one ectopic pregnancy. Of 16 deliveries after 24 weeks, first and second trimester bleeding occurred in 40% and 33%, respectively, 4 (25%) had preterm deliveries and the caesarean section rate was 88%. Two (13%) women developed proteinuric hypertension and two others had preterm spontaneous rupture of the membranes. Fourteen of 16 cases were delivered by caesarean section. The rate of primary postpartum haemorrhage was 3/15 (20%). The mean birthweight of term babies was 3.39 kg (SD 0.64) and none required admission to neonatal intensive care. There was one (6.7%) case of fetal growth restriction. CONCLUSION: Although this study is relatively small, there is an increase in delivery by caesarean section. There does not appear to be any other major excess obstetric associated risk when the demographics of the population in question is considered.

Fibroid arising in a müllerian duct remnant and presenting as a pelvic mass in a patient with vaginal agenesis: an unusual finding.

We report a case of vaginal agenesis associated with a large fibroid arising from a Müllerian duct remnant. Vaginal agenesis is rare and infrequently encountered by gynaecologists. Its association with a pelvic mass is even more uncommon, and a medline search by the authors has failed to uncover another reported case. We provide the clinical details of this case and discuss the differential diagnoses.

Laparoscopically-assisted vaginal hysterectomy for fibroid uteri weighing at least 500 grammes.

We retrospectively reviewed the medical records of 13 women who underwent laparoscopically-assisted vaginal hysterectomy (LAVH) where the uterus weighed 500 g or more. LAVH was successfully performed in 10 of these 13 women for whom the mean uterine weight was 619 g, mean operating time 99 minutes, and mean postoperative hospital stay 3.7 days. One of the 3 women who underwent abdominal hysterectomy required blood transfusion for intraoperative bleeding. There was no febrile or other operative morbidity associated with any patient. As up to 75% of hysterectomies are performed abdominally, LAVH may replace many abdominal hysterectomies for large fibroid uteri when vaginal hysterectomy is not feasible.

Uterine fibroids: the elephant in the room.

Uterine fibroids (leiomyomas) have historically been viewed as important chiefly as the major indication for hysterectomy. As new therapies are developed, the heterogeneity of this disease becomes therapeutically relevant. An awareness of the role of genetics, the extracellular matrix, and hormones in tumor etiology is key to understanding this disease.
