A Rare Case of Grade 1 Endometrioid Adenocarcinoma of the Uterus With Omental Metastasis with Brenner Tumor of the Ovary in a Postmenopausal Female.

Early-stage endometrial cancer may have microscopic omental metastases which is associated with a poor prognosis. There are no standard guidelines for omentectomy in early-stage endometrial cancer without risk factors. Brenner tumor is a rare ovarian tumor which is usually benign, but rarely, it may be malignant. Some Brenner tumors are endocrinologically active. Various studies have shown an association of Brenner tumor with endometrial hyperplasia, polyp, or early-stage carcinoma, probably due to its estrogen-secreting nature. We report a rare case of well-differentiated endometrioid adenocarcinoma of the uterus with <50% myometrial invasion with omental metastases associated with benign Brenner tumor of the ovary in a postmenopausal female.

Impact of SurePath® liquid-based preparation in cytological analysis of peritoneal washing in practice of gynecologic oncology.

CONTEXT: Peritoneal washing is performed for staging of gynecologic tumors to detect subclinical intraperitoneal metastases. AIM: The aim of the present study was to assess the impact of SurePath™ liquid-based cytology (LBC) in peritoneal washing in various gynecological malignancies. SETTINGS AND DESIGN: An audit of peritoneal-fluid/washing (January 2012 to July 2013) was performed with corresponding gynecologic specimens. All peritoneal washings were processed using both conventional and LBC technique. Suspicious cases on cytology were reported along with gynecologic specimens. RESULTS: There were a total of 393 peritoneal fluids. Eighty-three (21.1%) were positive for malignancy, and the corresponding histology was available in 352 (89.6%) cases. Sixty-nine positive samples had ovarian malignancies and 5 had uterine causes. There were 9 cases of peritoneal washings in which no histopathology was available. The most common cause of positive peritoneal cytology was ovarian serous carcinoma in 55/84 (65.5%) cases. Other causes included mucinous cystadenocarcinoma, dysgerminoma, squamous cell carcinoma in teratoma, yolk sac tumor, and granulosa cell tumor. Uterine causes included 2/45 (4.4%) cases of endometrioid adenocarcinoma, » (25%) cases of clear cell carcinoma, ½ (50%) cases of carcinosarcoma, and » (25%) cervix carcinoma. On review of positive cases (n = 83), 10 cases were identified, which had nil (n = 4) to low cellularity (<3 tumor clusters/smear; n = 6) on conventional smears, and were confirmed malignant on LBC. CONCLUSIONS: The most common ovarian malignancy causing positive peritoneal cytology is papillary serous carcinoma. Endometrioid adenocarcinoma rarely leads to positive peritoneal cytology. LBC technique leads to concentration of tumor cells causing reduction in false negative cases, especially in hemorrhagic and low-cellular cases.
