Diffuse hemangiomatosis of the liver and spleen in an adult

Diffuse hemangiomatoses are extremely rare in adults. The etiology and natu ral history of the disease are not well understood. A case of diffuse heman giomatosis of the liver and spleen associated with progressive liver failur e, thrombocytopenia, and disturbance of blood coagulation (comparable to Ka sabach-Merritt syndrome) is presented in a 62-year-old male. We describe th e histopathological and immunohistochemical findings and illustrate the mor phological aspects of differential diagnosis, distinguishing the disease fr om other vascular proliferations.
