title: Abdominal cryptococcoma in AIDS: a case report.
abstract: Cryptococcosis is a recognized opportunistic pathogen in the acquired immune deficiency syndrome. Although central nervous system infection and disseminated cryptococcosis is common in acquired immune deficiency syndrome, localized infection is rare. We present a case of massive retroperitoneal and mesenteric adenopathy in a male homosexual patient with acquired immune deficiency syndrome with clinical and radiologic features suggestive of lymphoma. However, this was proven pathologically to represent cryptococcal infiltration of the lymph nodes. Our experience indicates that Cryptococcus neoformans should be included in the differential diagnosis of massive abdominal adenopathy in the acquired immune deficiency syndrome.
