A 67 year-old-man was hospitalized due to chronic pain and a large mass on the anterior chest wall. His medical history showed chest trauma in 1970, the reconstitution of the scenario revealed there was blunt trauma with swelling and rib fracture on the same side. Physical examination revealed an isolated large anterior chest wall mass. Chest radiography showed two bilateral irregular masses, chest computed tomography showed a large right chest wall tumor with pleural effusion, nodules of the right upper lobe and tumor of the left lower lobe without mediastinal lymphadenopathy. Whole body exploration showed only the chest disease. Transthoracic biopsy showed inflammatory reaction. Surgical biopsy by anterior thoracotomy of the right mass was performed under general anesthesia. Histological and immunohistological analysis revealed lymphoid diffuse large cell proliferation with positive staining of CD 20, BCL-6 and MUM1, confirming the diagnosis of diffuse large B-cell malignant lymphoma. Chemotherapy based on CHOP-21 (cyclophosphamide, doxorubicin, vincristine, and prednisolone) was administered with good response after three cycles. The patient was discharged under surveillance in good condition after the end of chemotherapy. We report an infrequent neoplasm with an unusual and subtle clinical presentation.
Case reportA 67 year-old-man was admitted to our department for a painful large right anterior chest wall mass who had for 2 months in the context of weight loss of 5 kg. His medical history showed chest trauma and tobacco smoking (30 package/year) weaned 10 years prior to presentation. Questioning about the chest trauma which had occurred in 1970 found that the patient has suffered a fall from height of 2 m onto a metal object causing acute pain and swelling of the chest wall. This swelling had been neglected with the patient self medicating with analgesic treatment. No interventions were made at the time. The swelling was renitent with moderate chronic chest pain certainly related to a rib fracture associated with hematoma of the chest wall. Clinical examination at admission revealed a 12x7 cm hard mass poorly defined and localized to the right anterior chest wall without inflammatory signs. The patient was in fairly good general condition and apyretic. The lymph nodes, subclavicular and cervical region were without anomaly, as were abdominal and pelvic examinations. Chest radiograph (Fig. 1) showed two abnormal irregular opacities localized to the right parahilar and in the left lower lobe. Chest computed tomography (CT) showed two abnormal masses with irregular contours, the first mass was larger and confined to the right chest wall with bone destruction and the old rib fracture (arrow in Fig. 2),
