Kaposi's sarcoma of the lung: radiography and pathology.

Abstract

Kaposi's sarcoma is a neoplasm of multifocal origin apparently derived from fibroblastic and vascular elements and predominantly involving the skin. In 10 to 20% of patients with the neoplasm, associated lesions may occur in the lymph nodes, gastrointestinal tract, liver, lungs, heart, bone, and spleen in order of decreasing frequency. Kaposi's sarcoma in a previously healthy person occurring in the internal organs without cutaneous lesions isexceedingly rare. Sucha case, with predominantly thoracic involvement is presented here.
