Background. Angiosarcoma is a rare tumor that accounts for 1-2% of all sarcomas in humans. Case. A 56-year-old man was admitted to the previous hospital with an abnormal shadow on chest X-ray. Chest computed tomography (CT) showed a right intrathoracic mass and right adrenal tumor. A transbronchial biopsy resulted in no definitive diagnosis, but a CT-guided biopsy of the lung mass and adrenal tumor revealed epithelioid angiosarcoma, an extremely rare tumor. The patient died 12 days after hospital transfer. Conclusion. We herein report a case of a rapidly enlarged epithelioid angiosarcoma.
key words: Epithelioid angiosarcoma, Hemothorax, CT-guided biopsy, Immunohistochemistry
