Primary Plasma Cell Leukemia Revealed by a Mandibular Lesion: A Case Report

M, Kumar SP, Krishnan M. A Rare Case of Hormone-Induced Plasma Cell Granuloma of the Gingiva

Plasma cell granuloma (PCG), also known as inflammatory pseudotumor, is of unknown etiopathogenesis. It commonly presents in the lungs and can also occur in the liver, kidney, brain, and heart. PCG is rare in the oral cavity and even rarer in the gingiva. The clinical and radiological presentation of this disease in the oral cavity appears to be aggressive in nature and is often misdiagnosed as a malignant lesion. Histopathology helps in distinguishing PCG of gingiva from other benign and malignant lesions of the gingiva. Amlodipine and cyclosporine-induced PCG of gingiva have been reported in the literature. This report presents a rare case of generalized plasma cell granuloma of the gingiva in an adult female patient who was on hormonal therapy for infertility. Treatment consisted of complete surgical excision of the lesion and extraction of teeth with a poor prognosis. Wound healing was uneventful during the one-year follow-up period with no signs of recurrence.
