Background. Extramedullary plasmacytoma is a tumoral lesion not associated with osseous lesions of plasma cells in the final stage of B-lymphocyte differentiation. Extramedullary plasmacytoma generally occurs in the region of the upper aerodigestive tract; but rarely occurs in hilar lymph nodes. Case. A 52-year-old man presented with a productive cough. Chest CT scan revealed a 40×30 mm tumor in the left pulmonary hilum. Tumor markers were within normal ranges, and there were no abnormal findings on bronchoscopy. The tuberculin skin test was positive. Because a malignant tumor could not be ruled out by preoperative examinations, the patient underwent thoracoscopic examination and biopsy. The biopsy specimen revealed extramedullary plasmacytoma with IgG and κ-chain monoclonality on immunohistochemical staining. Conclusion. We report a very rare case of extramedullary plasmacytoma.
