Kaposi's sarcoma is an uncommon neoplasm that occasionally involves the gastrointestinal tract in immunosuppressed individuals. Infection with human herpes virus 8 is known to be necessary for developing all forms of Kaposi's sarcoma. We report a renal transplant recipient who developed visceral Kaposi's sarcoma 18 months after the transplantation. ⋯ Standard forceps biopsies of the gastric lesions failed to make the correct diagnosis. However, endoscopic resection successfully led to the correct diagnosis of Kaposi's sarcoma and herpes simplex virus 8 infection as well. This is the first report of a patient with visceral Kaposi's sarcoma who underwent endoscopic resection that reliably confirmed histological diagnosis and the viral genome at the same time.
