Description
Caram and colleagues reported in 2026 a rare case of solitary bone plasmacytoma, a single tumor of plasma cells, hiding in the upper jaw of a 76-year-old woman. The lesion looked like a routine root infection near two front teeth, with a draining tract. Standard root canal treatment brought no improvement, which prompted referral for a tissue sample.
Caram's biopsy showed sheets of abnormal plasma-like cells with a heavy white cell infiltrate. Marker tests confirmed the cells were all of one clone, matching plasmacytoma. Full body checks ruled out multiple myeloma, the widespread form of this cancer, leaving the solitary diagnosis. The patient received 20 radiation sessions and stays stable under joint follow-up. The authors warn that lasting root-area lesions may not be dental at all, and early spotting matters because a solitary tumor can be a first sign of myeloma.
