Angiosarcoma pulmonar metastásico

Angiosarcoma involving the lung, usually a result of metastatic disease, is a rare disorder. Primary angiosarcoma of the lung is an extremely rare tumor. The lung is one of the most common sites of metastatic involvement, along with liver and lymph nodes. Hemoptysis is the most frequent presenting symptom even with diffuse pulmonary hemorrhage. Chest radiography may reveal a spectrum of findings ranging form normal to bilateral nodular lesions. Early diagnosis is not common because of the rarity of angiosarcoma in the lung and hence, low index of suspicion. The prognosis is generally poor, with a median survive of 9 months after diagnosis.
