Abstract

Angiosarcoma is a rare malignant vascular neoplasm, which can arise in the soft tissue of the skin, thorax, breast, digestive, female genital and urinary tracts. It poses a diagnostic challenge due to its variable morphological appearances and immunohistochemical staining pattern. We present here a rare case of a primary epithelioid angiosarcoma of the bladder, and discuss further the morphological appearances, important differential diagnoses, and specific immunohistochemical and genetic characteristics which aid in its correct diagnosis.
