Plasma Cell Granuloma of Mastoid: A Rare Case Report

Abstract

Plasma cell granuloma is a rare benign lesion which is found most frequently in the lungs, and rarely in the head and neck.[1] In this study, we present 22year old male with right sided otalgia, tinnitus, hearing loss and swelling over right postauricular region. On otoscopy, tympanic membrane was intact and dull and pure tone audiometry showed right mild conductive hearing loss. HRCT mastoid and MRI brain suggested CSOM with cholesteatoma. Intact canal wall mastoidectomy with debulking of tumour was done. HPE reported plasma cell granuloma (inammatory pseudotumour) which was conrmed by Immunohistochemistry. Post operative period was uneventful. This case report is being highlighted for its rarity and unusual presentation.
