Combined Mastocytoma-hemangioma in a Patient with Urticaria Pigmentosa.
A patient with long-standing urticaria pigmentosa presented with a pea-sized reddish to purplish papule on the posterior part of the right ear. Histopathologic examination revealed numerous dilated vascular structures in the upper dermis and mast cell infiltrations throughout the whole dermis, consistent with combined mastocytoma-hemangioma. The mast cells were strongly positive with Giemsa stain.
