Primary Pulmonary Epithelioid Angiosarcoma: A Rare Case Presentation of Bilateral Pneumothoraces.

Angiosarcoma is a rare malignant neoplasm with a very poor prognosis that originates from the vascular endothelium and accounts for only 1%-2% of all sarcomatous malignancies. It is most commonly present in the deep soft tissues. Still, a wide range of primary sites, including the adrenals, thyroid, skin, and bone, are encountered. Here, we report a 52-year-old female with a past medical history of hypertension who presented with chest pain. Her chest images showed bilateral pneumothoraces with diffuse cystic lung disease. She underwent bilateral video-assisted thoracoscopy with a tissue biopsy, which was consistent with epithelioid angiosarcoma.
