1/66. Efficacy of selective venous sampling to localize a small ovarian androgen-producing tumor.

    Two cases of androgen-producing tumors, including a sertoli-leydig cell tumor in a woman of reproductive age and a Leydig cell tumor in a postmenopausal woman, are reported herein. In both cases, only selective venous sampling was able to detect the presence of the androgen-producing ovarian tumors. ( info)

2/66. 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.

3/66. sertoli-leydig cell tumor.

    Sertoli-Leydig cell tumors belong to the group of sex-cord stromal tumors of the ovary. They account for less than 0,5% of all ovarian neoplasms. The majority of these tumors are benign, and almost all are localised unilaterally. Herewith, we describe an ovarian sertoli-leydig cell tumor in an 11-year-old girl. serum levels of estradiol and progesterone were mildly elevated. while testosterone and androstendion levels were raised to around three- and sevenfold upper normal limit respectively on presentation. A left salpingo-oophorectomy was performed. Microscopically, the tumor was intermediately differentiated. At 6 months follow-up, there was neither clinical nor sonographical evidence of recurrence, and almost all sex hormone levels had returned to within normal range. Treatment of this pathological entity has to be individualized according to patient age, stage of tumor and degree of differentiation. ( info)

4/66. 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. ( info)

5/66. 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.

6/66. 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.

7/66. 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.

8/66. Ovarian sertoli-leydig cell tumor, endometrioid-like yolk sac tumor, and Y-chromosomal material.

    Sertoli-Leydig cell tumors (SLCTs) are rare neoplasms, accounting for less than 0.2% of ovarian tumors. The endometrioid-like variant of yolk sac tumor (YST) is very rare, and the most extensive series reported only 8 cases. We present a case of ovarian SLCT with endometrioid-like YST in a patient with a 46,XX karyotype with Y-chromosomal material. A 26-year-old woman had undergone a right salpingo-oophorectomy for SLCT with endometrioid-like YST. Chromosomal analysis revealed a 46,XX karyotype with Y-chromosomal material insertion into chromosome 1. The patient's father and sister, and 7 other paternal relatives (4 male and 3 female) presented the same chromosome variant without evidence of cancer. The YST component relapsed to the right side of the uterine wall and then metastasized to the peritoneum and liver, while SLCT was eradicated with primary surgery. Several chemotherapeutic regimens were totally ineffective to control tumor progression. She died of disease progression 54 months after the diagnosis. We adopted the policy of a close surveillance for ovarian neoplasms for the 22-year-old sister of the patient, who presented the same Y-chromosomal material in her karyotype. In very rare tumors, new methods, based on molecular and cytogenetic models, are requested to define recommended management. ( info)

9/66. Pelvic washing cytology of ovarian Sertoli-Leydig-cell tumor with retiform pattern: a case report.

    A Sertoli-Leydig-cell tumor is an exceptionally rare neoplasm. We present the pelvic washing cytomorphology of an ovarian Sertoli-Leydig-cell tumor with a retiform pattern in a 24-yr-old female. The cytologic features in this case were tight tissue fragments composed of small, relatively uniform cells with scanty cytoplasm and small rounded or blunt papillary fragments with hyalinized cores lined with small, mildly atypical cuboidal cells. Differential diagnoses included borderline and well-differentiated papillary serous tumors, clear-cell carcinoma, and collagen balls. Correlation of cytologic findings with histomorphology is crucial for correct interpretation of pelvic washings in cases of Sertoli-Leydig-cell tumors. ( info)

10/66. Direct laparoscopic venous sampling to diagnose a small Sertoli-Leydig tumor.

    BACKGROUND: Sertoli-Leydig cell tumors (SLCT) constitute only 0.5% of all primary ovarian neoplasms. We report a unique diagnostic method (selective laparoscopic venous sampling) and a rare case of a contralateral second primary tumor. CASE: A 14-year-old female presented with hyperandrogenic complaints and an increased serum testosterone. Ovarian origin was confirmed by direct laparoscopic ovarian blood sampling. A right salpingo-oophorectomy was performed. The pathological diagnosis was SLCT of intermediate differentiation. Three years later, the patient presented again with an increased serum testosterone. A solid tumor in the left ovary was excised. The pathology was SLCT of intermediate differentiation. The patient remains disease-free. CONCLUSIONS: Direct laparoscopic venous sampling is used to diagnose a small SLCT in a teenage patient. ( info)
