Primary lesion of multiple myeloma presenting as gingival swelling

It is rare that multiple myeloma (MM) occurs as a primary lesion in the jaws; we report such a case in an elderly patient involving the gingiva of the left posterior mandible. Multiple myeloma is a monoclonal malignant neoplasm of plasma cell origin which occurs in the bone marrow and may result in extensive destruction of skeletal structures. If the jaws are involved, it usually indicates an advanced stage of the disease.Thi s makes our case very unique due to the fact no other osteolytic lesions were identified at the time of the diagnosis of multiple myeloma. We report a rare case of multiple myeloma which was diagnosed from an intraoral gingival lesion on the lower left mandible.
