Tufted angioma, a particular form of angioma

Tufted angioma is a rare acquired cutaneous angiomatous proliferation characterized by slowly spreading erythematous macules and plaques, sometimes surmounted by nodular formations. Synonyms are progressive capillary hemangioma and Nakagawa's angioblastoma. Tufted angioma appears to be benign since follow-up studies did not report malignant transformation. This lesion must be distinguished from other vascular tumors, especially from Kaposi's sarcoma. If this lesion appears in an older patient, angiosarcoma should be excluded.
