Evolution of a case of lung plasma cell granuloma

Plasma cell granuloma, on lung inflammatory pseudotumour, is a localized benign proliferation of plasma cells and mesenchymal cells. We report the case of a 45 yr old male, who first presented with mild pain in the left side of the chest. Chest radiography was normal. Eight weeks later he had more pain and an opacity in the left and lower zones of his left chest. After another 7 weeks he had fever and cough with yellowish-green sputum. Chest X-ray then showed a round density in the left upper lobe. The final diagnosis was established after thoracotomy histological examination.
