Alveolar hemorrhage with epithelioid hemangioendothelioma. A previously unreported manifestation of a rare tumor.

Epithelial hemangioendothelioma (EH), originally termed intravascular sclerosing bronchioloalveolar tumor (IVBAT), is a rare pulmonary vascular neoplasm usually associated with an indolent but slowly progressive clinical course. We describe a patient with EH who presented with alveolar hemorrhage and died within 8 wk. This report extends the clinical spectrum of epithelial hemangioendothelioma to include this aggressive form. EH should be considered in the differential diagnosis of alveolar hemorrhage syndrome.

Ruptured mesenteric varices in hepatic cirrhosis: a rare cause of intraperitoneal hemorrhage.

We report a case of massive and fatal intraperitoneal hemorrhage from ruptured superior mesenteric varices secondary to portal hypertension and hepatic cirrhosis and proved by postmortem angioradiography. To our knowledge, this is the second case in the English language literature. Although very rare, this possibility should be borne in mind when one attempts to locate hemorrhagic complications of portal hypertension.

Quantification of melanin in hepatic and cardiac lipofuscin.

Melanin pigment in liver and heart tissue, obtained at autopsy from patients, was isolated and quantified. The quantity of melanin extracted was directly proportional to lipofuscin granule counts. Infrared and electron spin resonance spectographs of the isolated pigments from liver and heart showed absorption characteristics identical to those of known melanins. The pigment was absent in fetal and neonatal life, increased in brown atrophy of the heart and liver, and diminished in livers with fatty metamorphosis.
