Ecchymotic Kaposi's sarcoma.
We report two patients with ecchymotic patches that did not suggest the diagnosis of Kaposi's sarcoma. The principal complaint of one patient was facial and periorbital edema with bilateral periorbital ecchymosis. On his trunk were patches resembling pityriasis rosea-like Kaposi's sarcoma. Both types of lesions proved to be Kaposi's sarcoma on histologic examination. The second patient had scattered ecchymotic lesions, with typical lesions of Kaposi's sarcoma elsewhere on his body. The ecchymotic lesions showed a large amount of extravasated red blood cells and no evidence of amyloid. This variant has not been described previously to our knowledge.
