1/18. An ovarian Sertoli-Leydig cell tumour in a 40 year old Ethiopian woman: case report.

    Sertoli-Leydig cell tumors of the ovary are uncommon ovarian tumors. They belong to the ovarian stromal neoplasm. The most striking mode of presentation of these tumours is virilization due to androgen secretion. But approximately 50% of patients with Sertoli-Leydig cell tumors have no endocrine manifestations and usually complain of abdominal pain or swelling. Occasional tumors have been associated with various estrogen syndromes. A forty year old Ethiopian lady with well differentiated sertoli-leydig cell tumor of the left ovary presenting with features of virilization is described with clinicopathological correlation and literature review.

2/18. Mucinous cystadenoma coexisting with stromal tumor with minor sex-cord elements of the ovary: a case report.

    Mucinous neoplasms occur rarely in association with cystic teratoma, sertoli-leydig cell tumor, granulosa cell tumor or carcinoid tumor. Several cases of an ovarian stromal tumor with minor sex-cord elements have been reported in the literatures. However, there has been no report about an ovarian mucinous neoplasm coexisting with a stromal tumor with sex-cord elements yet. We report a case of an ovarian neoplasm composed of both mucinous cystadenoma and stromal tumor with minor sex-cord elements in a 58-yr-old female. The ovary including the mass measured 5 cm in size. On section, it revealed an unilocular cyst (4.5 cm in diameter) filled with mucinous fluid. There was a round, yellow, solid nodule, 1.5 cm in diameter within the wall. Microscopically, the cyst was lined by a single layer of endocervical mucinous epithelium and the nodule was composed of spindle cells showing an intersecting and whorled arrangement. There were cell nests showing polygonal shape with abundant cytoplasm among the spindle cells. They showed immunoreactivity for inhibin and did not have any connection with the adjacent mucinous epithelium. Therefore, we interpret the mucinous cystadenoma as having arisen de novo.

3/18. trisomy 8 as sole karyotypic aberration in an ovarian metastasizing sertoli-leydig cell tumor.

    Sertoli-Leydig cell tumors (SLCTs) represent a rare group of sex-cord stromal tumors of the ovary of unknown pathogenesis. We report a SLCT of intermediate differentiation with peritoneal recurrence and lymph node metastasis 12 months after removal, including cytogenetic analysis by comparative genomic hybridization and fluorescence in situ hybridization, which showed trisomy 8 as sole unbalanced karyotypic aberration. Our results provide evidence that a simple numeric chromosomal abnormality in SLCT may be associated with a malignant phenotype and suggest that the molecular pathogenesis of SLCT may be different from ovarian granulosa-stromal cell tumors.

4/18. sertoli-leydig cell tumor of the ovary, a rare cause of precocious puberty in a 12-month-old infant.

    We report a 12-month-old infant who presented with a 4-month history of isosexual precocious puberty secondary to an estrogenizing sertoli-leydig cell tumor of the ovary. Total serum immunoreactive inhibin and subunits A and B were markedly elevated before surgical resection and subsequently decreased 7 wk later into the normal prepubertal range. Twenty weeks following surgical removal, the patient presented again with central precocious puberty; inhibin B levels were raised on this occasion, a luteinizing releasing hormone stimulation test confirmed central precocious puberty. This is the youngest reported occurrence of this rare sex cord stromal neoplasm. The prognosis of this extremely rare tumor presenting at this early juvenile stage is uncertain. This report illustrates the usefulness of serum inhibin as a tumor marker during therapeutic suppression with leuprorelin acetate for central precocious puberty. Analysis of genomic and tumor dna revealed a normal nucleotide sequence for the LH receptor and the Galpha(s) gene. To understand the molecular pathogenesis of this tumor we analyzed mRNA levels for the inhibin A and B subunits, FSH receptor, LH receptor aromatase, steroidogenic factor-1 and the ER beta genes. Molecular characterization reveals the presence of genes specific for granulosa and leydig cells; the relative expression of these genes, in addition to its histologic characteristics, suggests that this tumor may result from a dysdifferentiation of a primordial follicle.

5/18. Ovarian tumor with functioning stroma.

    The authors reported two cases with ovarian tumors with functioning stroma. One was an ovarian carcinoid with testosterone-producing stroma and another was an ovarian mucinous cystadenoma with elevated serum level of estrogen. They appeared as multilocular cystic masses with varying signal on MR. This imaging feature was mimicking both those of Sertoli-Leydig tumors with heterologous elements and granulosa cell tumors, which are well known as functioning tumors. It had been reported in pathological literatures that any type of ovarian tumors can show hormonal activity due to functional stroma, although, it is the first report in the radiological literatures.

6/18. Sertoli Leydig cell tumour of ovary with heterologous element--a case report.

    A 16 years old female who presented with abdominal swelling and secondary amenorrhoea was subsequently diagnosed as Sertoli Leydig cell tumour of ovary revealing intermediate differentiation with heterologous element. The case is reported in view of its rarity.

7/18. Sertoli Leydig cell tumor with heterologous gastrointestinal epithelium: a case report.

    Sertoli Leydig cell tumour (SLCT) of the ovary with the presence of heterologous elements is very unusual. A case of SLCT with virilizing symptoms and androgenic endocrinological profile is presented. The tumor showed presence of heterologous element in the form of mucinous epithelium of the gastrointestinal type.

8/18. Ovarian sertoli-leydig cell tumor with coexisting vaginal angiomyxoma: case report and review of the literature.

    An extremely rare case of a postmenopausal patient with an ovarian Sertoli-Leydig cell tumour and a coexistent vaginal angiomyxoma is reported. A 71-year-old patient was admitted complaining of abdominal distension. A thorough diagnostic evaluation revealed a large tumour of the right ovary, and an oval-shaped greyish-white polypoid vaginal lesion. Total hysterectomy with bilateral salpingooophorectomy and lymph node sampling was performed, followed by excision of the vaginal lesion. Histological examination showed a Sertoli-Leydig cell tumour of the right ovary, and a vaginal angiomyxoma. Twenty-six months after the operation the patient is well with no signs of recurrence. To the best of our knowledge, no case of coexistence of an ovarian Sertoli-Leydig cell tumour with a myxoma has been previously reported.

9/18. Testicular sex cord-stromal tumours: the Edinburgh experience 1988-2002, and a review of the literature.

    AIMS: sex cord-stromal tumours of the testis are uncommon tumours, accounting for around 5% of testicular neoplasms. Treatment is primarily surgical, with no adjuvant therapy of proven benefit. We present a single-centre experience over a period of 15 years. MATERIALS AND methods: From 1988 to 2002, 18 patients with a diagnosis of sex cord-stromal tumour were referred to our centre. A retrospective analysis of their case notes was made and a pathological review undertaken. RESULTS: Sixteen were Leydig-cell tumours and two were Sertoli cell. For the Leydig-cell tumours, the median age at presentation was 42 years, 50% presented with a testicular mass and 31% with gynaecomastia. Two patients followed a malignant course: one revealing disease dissemination at initial staging, and a second 12 months after potentially curative orchidectomy. Salvage retroperitoneal lymphadenectomy in the latter patient proved unsuccessful. Clinical outcome correlated strongly with the presence of adverse pathological features described previously in the literature. After a median follow-up of 46 months, two patients have developed progressive disease, and two patients have died, one of metastatic Leydig-cell tumour. No patient defined as being of low malignant potential on pathological examination has relapsed outside our review period of 2 years. CONCLUSION: We confirm the overall excellent prognosis for most of the patients with sex cord-stromal tumours of the testis. Compared with most previous reports, pathological features seem to predict with reasonable accuracy the risk of malignant behaviour, and can adequately inform the subsequent review policy.

10/18. Sertoli-Leydig cell tumour in a postmenopausal woman showing all facets of the insulin resistance syndrome (IRS).

    Sertoli-Leydig cell tumours are rare sex stromal tumours with an incidence of < 0.5% of all ovarian tumours. Most frequently this tumour occurs in young women with a history of amenorrhoea, hirsutism and lowered pitch. Here, we report on a woman with IRS, postmenopausal virilization and increased testosterone levels due to a Sertoli-Leydig cell tumour. This is the first case to suggest an association between IRS and Sertoli-Leydig cell tumours. Furthermore, we highlight the difficulties in detecting this ovarian tumour with sonography.
