Solitary Plasmacytoma of the Mandible: A Rare Presentation.

Solitary plasmacytoma is a rare plasma cell neoplasm, most often arising in vertebrae and long bones; among these, mandibular involvement is exceptional. The following report documents a rare mandibular presentation in a 48‑year‑old female patient who presented with pain and swelling in the right lower jaw. Clinical examination, radiographic findings, and histopathology confirmed the diagnosis. The lesion was managed surgically with hemi‑mandibulectomy and reconstruction, with no recurrence to date. This case highlights the importance of early recognition of maxillofacial plasmacytomas by dental practitioners to enable timely diagnosis and improve treatment outcomes.
