title: Cutaneous angiosarcoma of the scalp mimicking a keratoacanthoma.
abstract: Cutaneous angiosarcoma (CA) has a wide range of clinical presentations. In this case report, we discuss a 78-year-old gentleman, who presented with a keratoacanthoma-like scalp lesion that turned out histologically to be a cutaneous angiosarcoma. A brief overview of CA, including its etiology, prognostic factors, clinical manifestations, and treatment options will also be discussed.
