title: Primary epithelioid angiosarcoma of the adrenal gland.
abstract: Primary angiosarcomas of the adrenal gland are exceptionally rare vascular tumors. We report a case of a 63-year-old man with an epithelioid angiosarcoma of the left adrenal gland. Visualized on computed tomography as a nonhomogeneous round mass, the tumor measured 3 cm in diameter. Histology showed a vascular tumor composed of epithelioid cells with vesicular nuclei and prominent nucleoli that lined irregular vascular spaces and also formed solid areas and showed pleomorphism and rare mitotic activity. Immunohistochemical stain confirmed the diagnosis of epithelioid angiosarcoma. We report our findings and review previously described literature cases of this rare entity.
