BACKGROUND We have previously reported that irradiation of mice in utero significantly increased the tumor incidence in the offspring of irradiated mothers. The joint effects of irradiation and cigarette smoking (CS) on tumor incidence and on the process of carcinogenesis were investigated. MATERIALS AND METHODS Pregnant C57Bl/6J female mice were irradiated with a single dose of gamma-ray (1 ...

A rare case of benign ovarian stromal cell tumor during pregnancy is presented. Because of a rapidly growing solid ovarian mass, 6 x 7 cm in diameter, a 21-year-old woman at 14 weeks of gestation was explored via laparotomy. Histopathological diagnosis was sclerosing stromal tumor of the ovary. She had no complaint of menstrual irregularities before pregnancy and there was no clinical or hormon...

Ovary tumor and pregnancy is a rare and serious condition with an unexpected outcome as it can interfere with the course of pregnancy. The authors report a case of a large juvenile granulosa cell tumor diagnosed at 33 weeks of pregnancy during a routine ultrasonographic examination. Pain, nausea and vomiting at the 35th week brought the suspicion of torsion.

AIM The aim of this report is to present the management of an aggressive, highly proliferative pregnancy tumor with clinical and radiographic characteristics highly suggestive of a malignant neoplasm. BACKGROUND Pregnancy tumor is a benign hyperplastic gingival lesion occurring during pregnancy that is indistinguishable from a pyogenic granuloma arising in nonpregnant females, or in males. Th...

We report a supratentorial primitive neuroectodermal tumor (sPNET) in 17-year-old primipara in the second trimester her pregnancy. Magnetic resonance imaging revealed a left frontoparietal mass with solid and cystic component. Gross-total resection was achieved via a left frontoparietal craniotomy. It was decided to suspend the radiotherapy and chemotherapy until the 30 weeks of gestation. But,...

Many factors that can modulate the risk of developing uterine leiomyoma have been identified, including parity. Epidemiological data on decreased risk of developing this disease has been subject to different interpretations regarding whether pregnancy per se is protective or, as leiomyomas are a major cause of infertility, women that develop these tumors are less fertile and thus have lower pre...
