title: A case of metastatic epithelioid angiosarcoma in the lamina propria of a sigmoid tubulovillous adenoma.
abstract: Epithelioid angiosarcoma is an extremely rare tumor. It is generally a secondary tumor and the preferred sites of such metastases are the heart, pericardium, lung, breast, liver, spleen, bone, and brain. In rare cases the lung has been described as the primary site. The prognosis of this neoplasm is extremely poor. We report a case of epithelioid angiosarcoma with multiple bilateral lung infiltration, bone metastasis, and metastasis of the lamina propria of a tubulovillous adenoma of the colon.
