Catamenial hemoptysis and pulmonary endometriosis: a case report.

Hemoptysis can be caused by a variety of pulmonary diseases, including parasitic infections, tuberculosis, chronic bronchitis and malignancies. Rarely, pulmonary endometriosis can present with hemoptysis and pose a diagnostic problem to clinicians. Pulmonary endometriosis can easily be confused with other clinical entities, including pulmonary embolism, pneumonia and pneumothorax.

Immunohistochemical comparison of uterine papillary serous and papillary endometrioid carcinoma: clues to pathogenesis.

Twenty-four predominantly papillary carcinomas of the endometrium, 10 serous and 14 endometrioid, were compared using a variety of immunohistochemical antibodies, including p53, estrogen and progesterone receptors, carcinoembryonic antigen, and E-cadherin. These were selected to attempt to find clues to explain the disparate behavior of these two tumor subtypes. We found that 6 of 8 (75%) serous carcinomas had a p53 reactivity score of 300, whereas 90% of endometrioid tumors had a p53 reactivity score of less than 20 (p = 0.

Clues to the pathogenesis of fallopian tube carcinoma: a morphological and immunohistochemical case control study.

The purpose of this study was to identify histopathological fallopian tube changes that might be related to the development of fallopian tube carcinoma (FTCA). Each of 14 unilateral cases of the latter was matched with 2 controls for age, hospital, and year of diagnosis. The uninvolved fallopian tube from patients with FTCA, all of which were of serous type, was compared to fallopian tubes from the same side in 28 matched controls.

Expression of angiopoietin-2 by human endometrial endothelial cells: regulation by hypoxia and inflammation.

The functional endometrial layer receives the implanting blastocyst, but is sloughed off during menstruation. Angiogenesis regulates growth and repair of cycling human endometrium. While vascular endothelial growth factor initiates angiogenesis, the angiopoietins (Angs) acting via the Tie2 receptor, are key regulators of subsequent angiogenic steps.
