Angiogenic non-Hodgkin T/natural killer (NK)-cell lymphoma: report of three cases.

Angiogenic T/natural killer (NK)-cell lymphoma is a non-Hodgkin lymphoma characterized by necrosis and vascular destruction that is strongly associated with Epstein-Barr virus and AIDS. Early diagnosis is essential to improve the chances of patient survival, but severe local inflammatory infiltrate impairs histologic diagnosis by obscuring neoplastic cells. The most common markers are CD2, CD56, cytoplasmic CD3, and CD43 EBV.

Spiradenocarcinoma of the breast arising in a long-standing spiradenoma.

The embryologic origin of the breast is related to salivary and sweats glands. Thus, breast neoplasms may show differentiation toward these tissues, although this is a rare event in humans. We report the clinicopathologic and immunohistochemical features of a 57-year-old woman presenting with a spiradenoma that originated in breast tissue and became malignant 40 years later.

Nonocclusive intestinal ischemia and necrosis after correction of interatrial communication with cardiopulmonary bypass. A rare and catastrophic complication.

The authors present a case of massive, nonocclusive intestinal ischemia and necrosis after surgery for correction of interatrial communication with cardiopulmonary bypass in a 22-year-old woman. This is an extremely serious complication that generally occurs in older patients. The literature mentions its occurrence in patients subjected to aortic valve replacement who have low cardiac output and in patients undergoing myocardial revascularization.
