Comments

This 74-year-old woman developed gradual discoloration of her forehead over a course of 2 months. Primary angiosarcoma typically presents on the head and neck of the elderly, men more often than women. These lesions are difficult to resect and prognosis is poor. Some cases are poorly differentiated and require immunohistochemical analysis to make the correct diagnosis, as in this case.

Description

At higher power of the same lesion, there is a hint of vascular formation with intralumenal red blood cells. Hemosiderin-laden macrophages are present. The lesional cells are atypical and epithelioid, with conspicuous nucleoli.
