1/21. Endodermal sinus tumour of the ovary in pregnancy.

    We present a case of a 30-year-old pregnant woman in whom an ovarian mass was identified by ultrasonography at 15 weeks' gestation. A markedly elevated maternal serum alphafetoprotein (MSAFP) suggested a diagnosis of endodermal sinus tumour of the ovary. A right salpingo-oophorectomy at 19 weeks' gestation enabled histological confirmation of the diagnosis and suggested a stage 1 tumour. Unfortunately tumour recurrence necessitated further laparotomy and delivery by caesarean section at 32 weeks' gestation. A total abdominal hysterectomy and left salpingo-oophorectomy was undertaken with resection of the splenic flexure and formation of a double-barrelled colostomy after which no gross intraperitoneal tumour remained. Three weeks later a new suprahepatic tumour mass was excised and the colostomy was closed. The patient then received four cycles of combination chemotherapy with cisplatin, etoposide, and bleomycin. Unfortunately she developed a faecal fistula at the site of the colostomy. Germ cell tumours are highly responsive to chemotherapy. Over-zealous surgery particularly involving bowel resection may cause unnecessary morbidity and compromise the outcome.

2/21. trisomy 12 in juvenile granulosa cell tumor of the ovary during pregnancy. A report of two cases.

    BACKGROUND: Granulosa cell tumors constitute only 5% of ovarian neoplasms, and their coexistence with pregnancy is extremely rare. Juvenile granulosa cell tumor has a good prognosis if it is confined to the ovary, but this type behaves more aggressively than the adult type at advanced stages. CASES: We report on successful completion of two singleton pregnancies and deliveries of normal infants in two young women with juvenile granulosa cell tumor diagnosed and treated during pregnancy. This tumor has rarely been described in association with pregnancy. The presence of trisomy 12 as a single chromosomal abnormality was detected in these two tumors. Both tumors were localized strictly to the ovary, so conservative surgery was applied and proved sufficient to remove all tumor tissue. Follow-up showed no signs of recurrence 18 and 53 months after the interventions. CONCLUSION: These cases support the contention that trisomy 12 is a nonrandom chromosome abnormality in juvenile granulosa cell tumors and that pregnancy may affect nuclear stability in this tumor.

3/21. pregnancy luteoma with granulosa cell proliferation: an unusual hyperplastic lesion arising in pregnancy and mimicking an ovarian neoplasia.

    A pregnancy luteoma (PL) was incidentally found at a term cesarean section in a 27-year-old black woman without any endocrine abnormality. The lesion involved only the left ovary; it had a nodular and focal pseudoalveolar growth pattern and was associated with areas of tubular sertoliform component, consistent with granulosa cell proliferation. immunohistochemistry revealed a diffuse positivity to Inhibin A, CD99, cytokeratin and vimentin. The ultrastructure was typical of steroid-producing cells. PL is a tumor-like lesion arising in pregnant women and often misdiagnosed as a neoplastic lesion; awareness of this rare entity and its differential diagnoses may avoid unnecessary surgery in young patients.

4/21. Pancreatic serous cystadenoma associated with islet cell tumour.

    We report the case of a 29-year-old female patient with a diffuse type of serous cystadenoma involving the entire pancreas except for part of the head, which was replaced by islet cell tumour. Ultrasound and CT showed multiple cysts in the entire pancreas and a solid mass with calcification in the head. MRI characterized the fluid content of the cysts and the extent of disease.

5/21. Management of recurrent juvenile granulosa cell tumor of the ovary.

    BACKGROUND: Juvenile granulosa cell tumors of the ovary are a rare form of neoplasm that makes up less than 5% of ovarian tumors in childhood and adolescence. About 90% are diagnosed in stage I with a favorable prognosis. More advanced stages (FIGO stages II--IV) have a poor prognosis. CASE: A patient was initially diagnosed at age 17 with FIGO stage IIIC disease and treated with a right salpingo-oophorectomy, debulking, and staging followed by six cycles of carboplatin and etoposide chemotherapy. Tumor recurrence in the liver and adjacent to the spleen occurred 13 months after completion of primary therapy. Aggressive surgical removal of tumor followed by six cycles of bleomycin and taxol as salvage chemotherapy resulted in 44 months of disease-free survival. On November 27, 2000, she had a cesarean delivery of a 2335-g normal male due to a breech presentation. Exploration revealed no evidence of tumor. CONCLUSION: This is the second case report of a patient with advanced juvenile granulosa cell tumor to become pregnant after apparently successful chemotherapy. These results are encouraging, but the best treatment for extensive and recurrent disease has yet to be determined.

6/21. Steroid cell tumour not otherwise specified during pregnancy: a case report and diagnostic work-up for virilisation in a pregnant patient.

    Steroid cell tumours not otherwise specified are rare ovarian tumours, which can cause foetal and maternal virilisation. This is the first case report that describes a steroid cell tumour not otherwise specified during pregnancy. Differential diagnosis, a diagnostic work-up and treatment are discussed.

7/21. Primary primitive neuroectodermal tumor of the ovary: a case report.

    Ovarian germ cell tumours having neuroectodermal cells, growing in patterns reminiscent of tumours of the central nervous system are rare. We report a case of primary primitive neuroectodermal tumor(PNET) of the ovary detected soon after pregnancy.

8/21. insulinoma in pregnancy presenting as a seizure disorder: a case report.

    We present the clinical course and problems in the management of a 30 year old Nigerian lady who was admitted with fasting hypoglycaemia due to a pancreatic islet cell tumour (insulinoma) during the first trimester of pregnancy. Her case was initially misdiagnosed as idiopathic epilepsy. The outcome was fatal mainly because the poor clinical state of the patient limited our treatment options. This condition though uncommon, is potentially easily recognisable and treatable, as long as there is a high index of suspicion.

9/21. Late recurrence of juvenile granulosa cell tumor of the ovary.

    Juvenile granulosa cell tumor (JGCT) of the ovary, if diagnosed at an early stage, has a favorable prognosis. Recurrences are uncommon but typically occur within the first year. The patient presented here was treated with a left oophorectomy after initial presentation. Tumor recurrence in the left adnexa, diagnosed 48 months later, was treated with cytoreductive surgery followed by chemotherapy; she remains disease free 19 months after this recurrence. Late recurrences of JGCT can occur and continued close surveillance is recommended.

10/21. Juvenile granulosa cell tumor associated with pregnancy: Report of a case and review of the literature.

    BACKGROUND: Juvenile granulosa cell tumors account for about 5% of all granulosa cell tumors and are diagnosed in nearly 80% of cases during the first two decades of life. Only 10% of granulosa cell tumors present during pregnancy. The incidence of ovarian malignancies during pregnancy varies from 0.05 to 0.07 per 1000 pregnancies. CASE: A 31-year-old pregnant woman was admitted to our university hospital due to an adnexal mass, 9.5 cm in diameter, which was detected at 34 weeks of gestation. At 37 5 weeks of gestation, a cesarean section with right salpingo-oophorectomy and removal of the tumor was performed. Histopathological findings, including immunohistochemical study, led to the diagnosis of juvenile granulosa cell tumor (JGCT). CONCLUSION: The histological features and the differential diagnosis of the JGCT are discussed. The optimal management of such adnexal masses during pregnancy is also discussed. A JGCT that is confined to the ovary appears to have an excellent prognosis and can be treated by unilateral salpingo-oophorectomy.
