Angiosarcoma of the scalp mimicking a sebaceous cyst

A 58-year-old Caucasian woman presented with a cystic lump behind the right ear that was clinically diagnosed as an infected sebaceous cyst. The lesion was treated with incision and drainage followed by antibiotics for 3 months. Because there was no resolution, a biopsy was performed that revealed a high grade angiosarcoma. She expired 2 months later. Cutaneous angiosarcoma is an extremely aggressive tumor. Therefore early diagnosis and management is crucial in providing better patient care.
