A 68-year-old patient presented with persistent hemoptysis and weight loss. A CT scan showing diffuse bilateral ground-glass opacities and nodules was followed by bronchoscopy. While diffuse alveolar hemorrhage (DAH) could be seen, specimens obtained during bronchoscopy did not provide conclusive histological findings. The decision was made to conduct video-assisted wedge resection, after which histological examinations revealed the diagnosis of bifocal nodular manifestation of an epithelioid angiosarcoma in the lung. Being a rare entity even among sarcomas, these kinds of tumors can be primary lung tissue angiosarcomas or metastatic lesions with primaries in places like the skin, breast, and heart. Treatment usually includes chemotherapy, but prognosis remains grim. This case highlights that in DAH, uncommon causes should be considered, and sufficient probe gathering is the key to early diagnosis and treatment.
