Ovarian large cell neuroendocrine carcinoma.

Ovarian large cell neuroendocrine carcinoma (LCNC) is a rare disease that is commonly associated with a surface epithelial and germ cell neoplasm component. A 46-year-old woman presented with a pelvic mass measuring 15 cm in diameter. She underwent an exploratory laparotomy with resection of the pelvic mass. Diffuse and nodular intra-abdominal disseminations were observed. Stage III LCNC associated with squamous differentiation alone of the right ovary was diagnosed. The patient died of progressive disease 4 months postoperatively despite paclitaxel and carboplatin therapy. Ovarian LCNC associated with squamous differentiation component alone has never been reported, but its prognosis may be poor.

Clinical outcome of metastatic uterine leiomyosarcoma and carcinosarcoma in a single institute.

AIM: To investigate the clinical outcome of uterine sarcomas, particularly in patients with pulmonary and abdominal metastasis, treated at a single institute. METHODS: We identified five patients with uterine leiomyosarcoma (LMS), one patient with endometrial stromal sarcoma (ESS), and three patients with carcinosarcoma (CS) between 2003 and 2006. RESULTS: All patients underwent at least hysterectomy and bilateral adnectomy. All five LMS cases (two patients in International Federation of Obstetrics and Gynecology stage I and three in stage III) recurred: one patient showed metastasis to the lung and four patients showed metastasis to the abdomen 16.6 months (mean) after hysterectomy. Two of three (66.7%) CS recurred: one patient showed metastasis to the lung and the other to the abdomen 5 months (mean) after hysterectomy. The ESS (stage I) patient showed metastasis to the lung 11 months after hysterectomy. Five patients with metastases received surgical interventions (two pulmonary resections and three abdominal resections), and all of these patients are currently alive 1.1-5.1 years postoperatively. Two patients with CS (stage I) and one patient with LMS (stage III) died of sarcoma dissemination, but neither of these three patients had undergone surgical intervention after hysterectomy (one for pulmonary and two for abdominal metastases). CONCLUSIONS: Resection of lung and abdominal metastases in uterine LMS and CS is beneficial to improve patient survival.

Retroperitoneal uterine leiomyoma occurring 5 years after hysterectomy for fibroids.

We encountered a 49-year-old, multiparous female with a very rare isolated retroperitoneal uterine leiomyoma measuring 72 x 43 mm in diameter occurring 5 years after hysterectomy for fibroids. The case was preliminarily diagnosed as right ovarian cancer or fibroma. An edematous, isolated solid tumor in the right retroperitoneal cavity was surgically resected. Pathological findings demonstrated uterine leiomyoma.
