Extensive hemangiomatosis of the extremities with the same histopathological pattern as the early lesion of Kaposi's sarcoma.

For 13 years a 28-year-old man had on his hands and feet bluish red patches, which had slowly progressed in size. Biopsy specimens exhibited an abnormal vascular pattern similar to that seen in early lesions of Kaposi's sarcoma. Skeletal radiographs of the hands and feet showed lesions indicating hemangiomatosis.
