Primary pleural angiosarcoma (PPA) is a rare and difficult-to-diagnose tumor often confused with other cancers like mesothelioma and lung cancer due to similar symptoms and imaging results.
A 52-year-old woman experienced severe shortness of breath and chest pain, with imaging revealing a large bleeding pleural effusion and medical thoracoscopy identifying abnormal pleura with nodular lesions.
Diagnosis was confirmed through histopathology with specific tumor markers, but unfortunately, the patient developed an infection and died before receiving treatment, highlighting the challenges in diagnosing PPA.
