title: Histiocytoid hemangioma with prominent fingernail involvement.
abstract: Only 2 cases of histiocytoid hemangioma localized in the nail apparatus have been reported in the literature. We describe here a patient affected by multiple histiocytoid hemangiomas involving the 3rd right digit and fingernail. The pathological features were typical for a diagnosis of histiocytoid hemangioma showing vascular proliferation characterized by enlarged endothelial cells associated with inflammatory cells. Phenotypic characterization of the proliferating cells confirmed their vascular origin.
