E-cadherin nuclear staining is useful for the diagnosis of ovarian adult granulosa cell tumor.

Ohishi Y, Kurihara S, Takeuchi T, Aman M, Kaku T, Kobayashi H, Wake N, Oda Y.Author information Department of Anatomic Pathology, Graduate School of Medical Sciences, Kyushu University, Fukuoka 812-8582, Japan. yohishi@surgpath.med.kyushu-u.ac.jpAbstractWe recently have demonstrated nuclear localization of E-cadherin in ovarian adult granulosa cell tumors (Histopathology 2011;58:423). The purpose of the present study is to investigate the diagnostic utility of E-cadherin nuclear staining for the differential diagnosis between ovarian adult granulosa cell tumor and its morphological mimics. Tissue samples taken from 81 ovarian tumors and 20 extraovarian tumors were immunohistochemically stained using monoclonal anti-E-cadherin antibody recognizing cytoplasmic domain (clone 36 supplied by BD Biosciences, San Jose, CA). The ovarian tumors consisted of 30 adult granulosa cell tumors, 3 Sertoli-stromal cell tumors, 14 fibrothecomas, 5 carcinoid tumors, 1 large cell neuroendocrine carcinoma, 18 endometrioid adenocarcinomas, and 10 poorly differentiated serous adenocarcinomas. Extraovarian tumors consisted of 16 uterine endometrial stromal neoplasms and 4 pulmonary small cell carcinomas. Only tumor cells with nuclear staining were considered positive in this study. Ninety percent of adult granulosa cell tumors, 67% of Sertoli-stromal cell tumors, 64% of fibrothecomas, 75% of endometrial stromal neoplasms, 75% of small cell carcinomas, and the one large cell neuroendocrine carcinoma showed E-cadherin nuclear expression, whereas all the ovarian carcinoid tumors, endometrioid adenocarcinomas, and poorly differentiated serous adenocarcinomas were negative. E-cadherin nuclear staining is useful in distinguishing between adult granulosa cell tumors and ovarian adenocarcinomas or carcinoid tumors. However, it is of limited use for distinguishing between adult granulosa cell tumors and endometrial stromal neoplasms or small cell carcinomas. E-cadherin should be included in the immunohistochemical panel for an accurate diagnosis of ovarian adult granulosa cell tumors.

Bilateral androblastoma (Sertoli-stromal cell tumor) of the ovary: a rare cause of virilization in a teenager.

Warenik-Szymankiewicz A, Słopień R, Gaca M, Kedzia H, Kadziołka P, Opala T.Author information Department of Gynecological Endocrinology, University of Medical Sciences of Poznań, Poland.AbstractA case of a 17-year-old patient diagnosed with bilateral androblastoma of the ovary is presented. The patient was admitted because of secondary amenorrhea, hirsutism and acne. After clinical, ultrasonographic and hormonal examinations an androgen-producing ovarian tumor was suspected and consequently laparotomy with right ovarian tumor excision and left ovary exploration was carried out. During surgery the right ovarian tumor was excised and exploration of the left ovary revealed an ovarian tumor with a diameter of 10 mm, which was then also excised. The pathologic diagnosis was a bilateral androblastoma of the ovary measuring 40 mm x 30 mm x 20 mm in the right ovary and 10 mm in diameter in the left ovary. We concluded that androblastomas, in spite of their low incidence, are a possibility that should always be considered in women of all ages presenting with signs of virilization.

Weight reduction and pioglitazone ameliorate polycystic ovary syndrome after removal of a Sertoli-stromal cell tumor.

Baba T, Endo T, Ikeda K, Shimizu A, Morishita M, Kuno Y, Honnma H, Kiya T, Ishioka S, Saito T.Author information Department of Obstetrics and Gynecology, Sapporo Medical University, Sapporo.AbstractThis report presents an unusual case of Sertoli-stromal cell tumor and polycystic ovary syndrome successfully treated with weight reduction and an insulin-sensitizing agent. A 22-year-old woman, gravida 0, para 0, visited our hospital for the first time with a 12-year history of secondary amenorrhea and hypertrichosis. Transvaginal ultrasonography revealed a solid tumor in the right ovary. Right salpingo-oophorectomy was performed and pathological examination confirmed a Sertoli-stromal cell tumor. The patient's serum androgen levels declined postoperatively, but remained above normal. Pioglitazone treatment for 6 months also significantly reduced serum androgen levels, but they still remained above normal. However, after losing 12 kg of body weight, the patient's serum androgen levels declined to normal, and spontaneous menstruation became regular. Weight reduction with pioglitazone is an effective means of treating hyperandrogenism.
