Although the pleura can be frequently invaded by lymphoma, primary pleural lymphoma is rare and relevant published literature are all case reports (1). It is usually divided into two types: primary effusion lymphoma (PEL) and pyothorax-associated lymphoma (PAL) (2). Primary pleural lymphoma without pleural effusion and history of chronic pyothorax is extremely rare and evidence-based decisions are few.
