Primary pulmonary epithelioid angiosarcoma presenting as a solitary pulmonary nodule on image

Primary angiosarcoma of lung is a rare condition. Only about 20 cases have appeared in English published reports so far. Its rarity and consequent low index of suspicion makes clinical diagnosis difficult. Pathological diagnosis of the epithelioid variant of pulmonary angiosarcoma is particularly challenging. We report a case of primary pulmonary epithelioid angiosarcoma as a solitary pulmonary nodule in image study in a 41-year-old man with a brief review, to contribute it to the sparse literature on this disease.
