Primary chest wall lymphoma with no history of tuberculous pyothorax: Diagnosis and treatment

Objective Primary chest wall neoplasm represents only 5% of chest wall neoplasm and among them primary chest wall lymphoma is uncommon. Methods A 28-year-old man had no history of tuberculous pyothorax or artificial pneumothorax therapy but did have a 4-month history of dyspnea, fever, chills, and night sweats. On physical examination, a mass about 10 × 10 cm was noted on the anterior chest wall on the right side, and computed tomographic scan demonstrated that it originated from the pleural wall. A 42-year-old man was admitted with intermittent left hemithoracic pain from about 6 months before his visit. A 5 × 5-cm tender mass in the posterior wall of the left hemithorax was palpated. Computed tomography showed mild plural effusion and erosion in the posterior segment of the left ninth rib. Surgery was performed for histologic diagnosis. Results With the diagnosis of large B cell lymphoma, chemotherapy was prescribed for the first patient, and the patient has been in complete remission for more than 5 months. For the second patient, the left ninth rib along with the originated mass was completely resected and chemotherapy was prescribed. The patient has been in complete remission for more than 8 months. Conclusion Treatment of primary chest wall lymphoma was not clear and various treatment strategies were considered. Remission of considerable duration in our patients leads us to suggest that surgery followed by adjuvant chemotherapy can provide a reasonable outcome in patients in whom the chest wall lymphoma is the only site of disease.
