We present a case of a 73-year-old woman who developed a small lesion on her tongue.
The nodule was resected and hobnail hemangioma was diagnosed. Hobnail hemangioma
is a rare vascular lesion with unusual morphology, including bland cells
with hobnail appearance, biphasic grow pattern with superficial dilated vessels and
slit-like vessels in the deeper portion of the lesion. The infiltrative pattern of grow
may cause misdiagnosis. The differential diagnosis with hemangioendothelioma variants,
low grade angiosarcomas and Kaposi sarcoma is of particular concern. The lack
of recognition of this uncommon entity may result in excessive and unnecessary treatment.
