Abstract

Twenty-two cases of pulmonary plasmacytoma have been reported in the literature and verified by immunohistochemistry or other diagnostic tests. The treatment for this rare tumor has included various combinations of surgical resection, chemotherapy, and radiation therapy. We report a case of a middle-age man who underwent endoscopic debulking followed by laser ablation for a pulmonary plasmacytoma, which showed a prominent endobronchial location with clinical and histopathologic verification.

Extramedullary plasmacytomas are extremely uncommon neoplasms of plasma cell derivation. The vast majority of tumors arise in the head and neck region, especially in the upper respiratory tract [6]. Typically in the lung they present as a solitary nodule or less commonly as lobar consolidation or diffuse pulmonary infiltrates 1, 2, 3, 4, 5. Although plasmacytomas frequently involve lung and the large airways, an exophytic growth into the bronchial lumen is uncommon. Our review of the
