Primary malignant lymphoma of the chest wall without chronic pyothorax

Abstract

An 83-year-old man was referred to our hospital complaining of pain and swelling of the right chest wall. Chest radiograph and CT revealed a tumor shadow in the right chest wall. It was diagnosed as malignant lymphoma by incisional biopsy. Firstly, radiation therapy was conducted, and an operation was performed. Histopathologically, this tumor was diagnosed as a malignant lymphoma (non-Hodgkin, diffuse lymphoma, large cell anaplastic type). We herein report a rare case of malignant lymphoma from the chest wall without preceding chronic pyothorax. It is necessary to accumulate more cases to investigate tumor development and establish treatment.
