A case of angiokeratoma.
Angiokeratoma is described by various authors as a rare variant of the hemangioma in the dog, characterized by a vascular component, like all types of vascular neoplasms, but also by an epithelial component. A case of angiokeratoma is described in a male 8-year-old dog. The tumor was located in heavily pigmented skin on the anterior surface of the front limb and not in the more usual previously described locations, eyelid and conjunctiva. Microscopic examination revealed a well-circumscribed mass with irregular hyperplasia of the epidermis and dilated vascular spaces filled with blood in the superficial dermis.
