Sclerozing stromal tumor of the ovary is an extremely rare neoplasm occurring predominantly in the second and third decades of life. Most patients have menstrual irregularities and
pelvic pain
. Infertility and endometrial pathology have also been described. A 34-year-old woman presented with hirsutism and oligomenorrhea of three months duration. Ultrasound examination showed a heterogeneous right ovarian tumor consisting of predominantly solid tissue with several loculated cysts. On T2-weighted pelvic MR images, signal intensities of the cystic components were high and those of the solid components were heterogeneous, ranging from intermediate-high to high. Dynamic MRI marked early enhancement of solid components in the right ovary. The specimen obtained from endometrial curettage showed proliferative endometrium. Preoperative serum levels of tumor markers were in normal range: preoperative serum levels of testosterone (T) (2.42 ng/ml; normal for adult females 0.1-0.8 ng/ml) and dehydroepiandrosterone-sulphate (DHEA-S) (232.4 microg/dL; normal for adult female, 35-430 microg/dL) were measured and the T value was found increased. At laparotomy, a left ovarian mass was found attached to the right infundibulopelvic ligament and a left oophorectomy was performed. The mass was described as benign by frozen analysis. Definitive histopathological diagnosis was sclerozing stromal tumor of the ovary (SST). The histologic features included a pseudolobular pattern with focal areas of sclerosis and a two-cell population of spindled and polygonal cells. Immunohistochemical studies showed positive smooth muscle actin and negative cytokeratin,
keratin
, S100 and desmin. The T value decreased postoperatively (0.57 ng/ml).

The diagnosis of malignant melanoma metastatic to the ovary is rare. The primary lesion can be followed by metastasis site after few years. We describe the case of a 31 year-old woman who presented an acute
pelvic pain
in relation with a right ovarian cyst. This patient presented many metastatic melanoma few years ago. The ovarian metastatic diagnosis is strongly suspected by the use of preoperative magnetic resonance imaging. The operating piece immunohistochemical studies demonstrated the positivity for S-100 protein, HMB-45 and negativity for
keratin
in cytoplasm cells. The surgical treatment (right salpingo-oophorectomy) would be followed by chemotherapy. The patient had a good postoperative recovery. She is in good health at six months.

Nonsmall cell neuroendocrine carcinoma (NSCNEC) of the ovary is a rare and aggressive tumor commonly associated with other surface epithelial and germ cell neoplasms. In this study, we present the clinicopathologic and immunohistochemical features of 11 such cases seen at The University of Texas M.D. Anderson Cancer Center in a 16-year period (1990 to 2005). Patients ranged in age from 22 to 63 years (mean 46.7). The most common presentation was abdominal/
pelvic pain
(6 cases), followed by ascites (2 cases), pelvic mass, vaginal bleeding, and abdominal bloating (1 case each). Tumors were mostly unilateral, cystic, or solid/cystic and ranged in size from 5 to 26 cm (mean 16.2). In 8 cases, NSCNEC was associated with other epithelial neoplasms, including mucinous neoplasms of low malignant potential, mucinous carcinoma, endometrioid carcinoma, mixed endometrioid and mucinous carcinoma, and a high-grade carcinoma, not otherwise specified. In 2 cases, the tumor was associated with a mature cystic teratoma; one of them also containing an invasive moderately differentiated adenocarcinoma. A single case was associated with a benign ovarian cyst. The latter case had a dermoid cyst in the contralateral ovary. NSCNEC represented anywhere from 10% to 90% of the ovarian tumor. Microscopically, the neuroendocrine component was usually composed of large and/or intermediate oval to round cells. In 2 cases, the intermediate cells were intermixed with small cells. Three cases had also spindle cells. The neoplastic cells were mostly arranged in a solid pattern, nests, or trabeculae. All tumors had a brisk mitotic activity. Immunoperoxidase studies for
keratin
cocktail, cytokeratin (CK) 7, CK20, CAM 5.2, chromogranin A, synaptophysin, NSE, CD56, and c-kit were performed and the cases stained as follows:
keratin
cocktail 6/6, CK7 4/5, CK20 3/5, CAM 5.2 3/3, chromogranin A 8/11, synaptophysin 9/9, NSE 1/1, CD56 4/8, and c-kit 5/7. According to the International Federation of Gynecology and Obstetrics staging system, 4 cases were stage I tumors, 3 cases were stage III tumors, and 4 cases were stage IV tumors. Seven patients were treated with total abdominal hysterectomy and bilateral salpingo-oophorectomy followed by chemotherapy. One patient had a bilateral salpingo-oophorectomy with omentectomy and appendectomy followed by chemotherapy; 1 patient had a total abdominal hysterectomy with right salpingo-oophorectomy followed by chemotherapy; one had a bilateral salpingo-oophorectomy followed by chemotherapy, and one had a right salpingo-oophorectomy with appendectomy followed by chemotherapy. Five patients died of disease at 2, 3, 9, 20, and 36 months. One patient is alive with disease at 8 months and 5 are alive without evidence of disease at 11, 28, 37, 66, and 68 months. Four of 5 patients who died of disease had either stage III or IV tumors and 3 of 5 patients who are alive without evidence of disease have stage I tumors. In summary, ovarian NSCNEC is an aggressive tumor with a tendency to present at advanced stage and cause death within a mean of 17 months after diagnosis; however, some patients, particularly those with stage I disease and/or those who have received platinum-based therapy, may have a more favorable prognosis.

Angiosarcoma is a high-grade vascular tumor arising from endothelial cells of blood vessels. It represents less than 1% of the mesenchymal tumors. Uterine angiosarcoma is an extremely rare tumor with less than 25 cases reported in the literature. It usually presents in postmenopausal women as uterine mass and rarely can arise in a leiomyoma. It is included in the group of tumors of aggressive behavior and poor prognosis. Herein, we present a case of primary uterine angiosarcoma in a 56-year-old female patient with a history of fibroids presenting with
pelvic pain
and weight loss. Abdominal CT scan showed a large uterine mass and enlarged pelvic lymph nodes. Total abdominal hysterectomy with bilateral salpingo-oophorectomy was performed, and on histopathologic examination, it was found to be primary epithelioid angiosarcoma of the uterus. Immunohistochemical stains for CD31,
keratin
MAK-6, and
keratin
AE1/AE3 confirmed the diagnosis. In conclusion, uterine angiosarcoma should be suspected in any rapidly growing hemorrhagic uterine mass, and appropriate sampling and immunohistochemical stains should be considered.
