title: Metastasis of mediastinal epithelioid angiosarcoma to the finger.
abstract: Epithelioid angiosarcoma (EA) is a rare malignant, vascular tumor that is usually observed in middle-aged and elderly males. Cutaneous metastasis of EA is extremely rare. We report the case of a 41-year-old woman presenting with a painful bluish, bulla-like lesion on the distal extent of the left third finger. The patient had recently been diagnosed with mediastinal EA with disseminated metastases. The skin biopsy specimen revealed metastatic EA. This is thought to be the first reported metastasis of EA to the finger. Whenever a patient has metastatic disease, acrometastases should be considered in the differential diagnosis of inflammatory lesions of the digits and a skin biopsy should be performed.
