Abstract

A 25-year-old man presented with painful right lateral chest wall swelling of two months duration. Computed tomography showed moderate pleural effusion with extension into the lateral chest wall. Aspiration revealed frankly hemorrhagic fluid that was exudative in nature. Fine needle aspiration cytology (FNAC) and cell block preparation of the chest wall swelling revealed a malignant round cell tumour. Immunohistochemical assays, together with the clinical and radiologic findings led to the definitive diagnosis of a peripheral neuroectodermal tumour (PNET).
