RESUMO
Ovarian fibroma is the commonest benign tumor of the ovarian stroma. The cellular subtype accounts for around 10% of ovarian fibromatous tumors. The cellular fibroma is a tumor of uncertain malignant potential that may recur or be associated with peritoneal implants. Usually these are solid tumors, sometimes with small areas of cystic degeneration. This case is reported to highlight an unusual feature for an ovarian fibroma: the tumor was predominantly cystic with a small solid part; the multiple cavities contents consisted of viscous liquid that solidified under room temperature. The multiloculated cysts, the mucinous contents, and the solid areas simulated a borderline mucinous ovarian tumor on both CT scan and gross pathologic examination.
RESUMO
We present a rare case of a 68-year-old postmenopausal woman with a mobile, hard, and painless pelvic abdominal mass that was palpated to the umbilical scar. Ultrasonography demonstrated a solid mass in the upper pole of the right kidney and a predominantly solid pelvic abdominal mass. Serum testosterone was 413 ng/dL. The patient underwent laparotomy on the renal tumor, which was thought to have a probable ovarian metastasis. Bilateral ovariectomy and right nephrectomy were performed. Immunohistochemical and histopathologic assessment identified a right ovarian Sertoli cell tumor, a left ovarian serous cystadenoma, and a mixed epithelial-stromal tumor in the kidney with positive hormonal receptor. Because our patient had an ovarian neoplasm producing steroids and a kidney tumor expressing hormonal receptors, the hypothesis of possible endocrine dependence in the pathogenesis of mixed epithelial stromal tumor is reinforced.

CONTEXT: Cellular angiofibroma of the vulva is a rare tumor that was first described in 1997. It occurs in middle-aged women (average age: 47 years), has small size (< 3 cm) and well-circumscribed margins. CASE REPORT: We describe a case in a 51-year-old woman whose preoperative diagnosis was confounded with Bartholin's glandular cyst. The neoplasia was well delimited and made up of three characteristic components: fusiform cells forming small fascicles, numerous blood vessels and adipose tissue interspersed between the fusiform cells. The stroma cells were positive for vimentin and negative for CD34, protein S-100, actin and desmin. The differential diagnoses for this tumor include aggressive angiomyxoma, angiomyofibroblastoma, lipoma of fusiform cells, solitary fibrous tumor, perineurioma and leiomyoma.

The aim of this study was to verify the presence of bacterial vaginosis (BV), Candida sp, Chlamydia trachomatis, Neisseria gonorrhoeae, to determine the prevalence of tobacco use and measure vaginal pH (VpH) in pregnant women with (n = 26) and without (n = 26) human papillomavirus (HPV) infection, and make comparisons between these 2 groups. HPV, C. trachomatis and N. gonorrhoeae were diagnosed using hybrid capture, BV using clinical criteria, and Candida sp via cultures. A digital pH meter was used to measure VpH. The frequencies of Candida sp were 19.2 and 23.1% (p = 1), and VpH was 4.4 +/- 0.4 and 4.3 +/- 0.4 (p = 0.23), in the HPV-positive and HPV-negative groups, respectively. Compared to the group of pregnant women without HPV infection, those with HPV infection had a significantly higher prevalence of tobacco use (50 vs. 11.5%; p = 0.006), BV (53.8 vs. 15.4%; p = 0.007), and C. trachomatis (34.6 vs. 7.7%; p = 0.039). No case of N. gonorrhoeae was diagnosed. All cases of C. trachomatis and BV had high-grade HPV infection.

We describe the case of a patient who reported a 4-month history of edema in the lower right limb, which was accompanied by pain and paresthesia and which progressed to flaccid paraplegia. Two years earlier she had undergone a uterine curettage for hydatidiform mole. Metastases of a choriocarcinoma to the lumbar and sacral segments of the column were diagnosed.
