Moyamoya disease is a rare condition characterized by angiographic evidence of bilateral narrowing and occlusion of the internal carotid arteries, along with the presence of an abnormal capillary network of vessels at the base of the brain. Clinically, this disease is found with a higher incidence in young female, but there are few cases of moyamoya disease in pregnancy. We describe two cases of pregnancy with known moyamoya disease, which have delivered successfully by elective cesarean section with epidural anesthesia.

This study assessed the feasibility of F-18-fluorodeoxyglucose positron-emission tomography (18F-FDG PET) in the post-therapy surveillance for patients with endometrial cancer showing no evidence of disease (NED). From April 1997 to June 2007, 127 patients with endometrial cancer showing NED were performed 18F-FDG PET scan. The feasibility of 18F-FDG PET for the early detection of recurrence in patients with endometrial cancer was evaluated retrospectively. Of the 127 patients, 32 patients showed positive lesions on 18F-FDG PET scan. Nineteen (19/127 cases, 15%) of them were confirmed to have a recurrence clinically or histologically. The sensitivity, specificity and positive and negative predictive value of 18F-FDG PET for detecting recurrences in patients with endometrial cancer were 100%, 88%, 59% and 100%, respectively. In conclusion, 18F-FDG PET may be a useful method for the post-therapy surveillance in patients with endometrial cancer.

Schwannomas arise from schwann cells in the peripheral nerve sheath, without involving the nerve fibers. Schwannomas are benign, slow-growing tumors that infrequently recur and rarely undergo malignant change. Also schwannomas of the female genitalia are considered extremely rare. We report a case of schwannoma of the clitoris. A 76-year-old woman without neurofibromatosis presented with a 2.0 × 1.7 cm, painless mass of the clitoris. Simple surgical excision of the mass was undertaken, and final pathology revealed schwannoma of the clitoris. No evidence of local recurrence was noted after 1 year of follow-up.

N/A From Jan. 1984 to Dec. 1993, 46 patients with malignant germ cell tumor of ovary were identified in tumor registry of Seoul National University Hospital. The clinicopathologic features of these patients were reviewed. The mean age of patient was 21.6 years (range 1-54), and common presenting symptoms were abdominal mass (19/46), abdominal pain (9/46), abdominal distension (7/46), and epigastric discomfort (2/46) in order. Dysgerminoma was the most common histologic type (19/46, 41.3%), followed by endodermal sinus tumor (13/46, 28.2%), mixed germ cell tumor (6/46, 13/0%), embryonal carcinoma(5/46, 10.8%), immature teratoma(2/46, 4.3%), and chorio- carcinoma (1/46, 2.1%). Among 6 mixed germ cell tumors, dysgerminoma mixed with endodermal sinus tumor component was the most frequent combination. Fifty percent of patients were with FIGO stage I, and 26% with stage III. Overall two year disease free survival was 89.1%. Patients with dysgerminoma showed more favorable 2 year disease free survival (100%) than endodermal sinus tumor or mixed germ cell tumor (84.6%, 66.6% respectively). Patients age, disease stage, histologic type and future child-bearings should be considered in the management of malignant ovarian germ cell tumor. Multicenter prospective randomized studies are needed to identify the more rational treatment strateges of these rare malignant tumors.
