Unusual uterine cervical polypoid mass presenting during pregnancy.

The authors encountered a case of uterine cervical adenosarcoma with sarcomatous overgrowth during pregnancy. Cytological images of atypical stromal cells in sarcoma components were obtained in this case.

Clear cell carcinoma of the lower uterine segment: A case report.

Uterine carcinoma of the lower uterine segment (LUS) is a rare tumor that accounts for 3-3.5% of cases of uterine malignant cancer. The tumor arises from the lower region of the uterine body through the upper region of the cervix. The present study reported a case of clear cell carcinoma that originated from the LUS. A 50-year-old woman visited a local hospital due to irregular vaginal bleeding. She was suspected to have a uterine tumor and was referred to Tachikawa Hospital (Tokyo, Japan). Transvaginal ultrasound and magnetic resonance imaging revealed a uterine tumor from the lower region of the uterine body through the upper region of the cervix. Endocervical curettage revealed clear cell carcinoma. Based on a diagnosis of clear cell carcinoma of the LUS, radical hysterectomy was performed with bilateral salpingo-oophorectomy, paraaortic lymph node dissection and omentectomy. Macroscopically, the tumor was limited to the lower region of the uterine body through the upper region of the cervix in the resected uterus. Histopathological findings indicated no tumors in the uterine corpus and uterine cervix, but clear cell carcinoma was observed in the LUS epithelium. At the 1-year follow-up, the patient remained free of local recurrence and metastasis. To the best of our knowledge, clear cell carcinoma of the LUS has not previously been reported. More cases are required to clarify the pathology.

Metastatic mucinous adenocarcinoma of the ovary is characterized by advanced patient age, small tumor size, and elevated serum CA125.

BACKGROUND/AIMS: An intraoperative diagnosis in cases with primary and metastatic ovarian carcinomas is important for adequate treatment. The aim of the present study was to find a reliable method to discriminate primary from metastatic mucinous adenocarcinomas (MACs) of the ovary intraoperatively. METHODS: Clinical features of all primary and metastatic mucinous ovarian carcinomas diagnosed from 1994 to 2008 at the Osaka University and Osaka Rosai Hospitals, Osaka, Japan, were reviewed retrospectively. RESULTS: Among the 73 MACs, 51 (70%) and 22 cases (30%) were diagnosed as primary and metastatic ovarian carcinomas, respectively. The distributions of tumor size, patient age, and serum CA125 level were significantly different between primary and metastatic cases. Our algorithm that categorizes patients ≥50 years whose tumor size was <10 cm into metastatic cases, and patients <50 years, or the ones whose tumor size was ≥10 cm, into primary tumors, provided an 84% accuracy in our population. CONCLUSIONS: A more reliable method to discriminate primary from metastatic MACs of the ovary by patient age and serum tumor markers was derived from our study population.

[An elderly patient with advanced non-small-cell lung cancer that responded remarkably to combination chemotherapy of vinorelbine and gemcitabine].

A 73-year-old man was admitted to our hospital because of hemoptysis in November 1999. A chest CT revealed a mass shadow in the right upper lobe and enlarged hilar and pretracheal lymph nodes. Bone scintigraphy showed a bone metastasis in right middle rib. He was treated with vinorelbine (25 mg/m2 days 1,8) and gemcitabine (800 mg/m2 days 1,8) every 3 weeks from December 1999. After 4 courses of chemotherapy, the primary tumor and hilar lymph node were remarkably reduced in size, and his hemoptysis disappeared and body weight increased. It is suggested that combination chemotherapy with vinorelbine and gemcitabine is effective for elderly patients with non-small-cell lung cancer with good performance status.
