Mohiyuddin SMA, Raju K, Sumanth KR, Karunasagar A, Maruvala S, Chaudhary S and Thomas L

Kimura’s disease (KD) is a rare immune mediated chronic inflammatory disorder of unknown etiology which involves subcutaneous plane and is usually seen in parotid region. It is also known to affect cervical lymph nodes and pharynx. There has been no report of this disease isolated to post cricoid region. We report a case of hoarseness of voice in an elderly lady who was found to have a smooth mass in post cricoid region with forward displacement and fixity of right arytenoid. She had eosinophilia and biopsy revealed lymphoid hyperplasia with infiltration of eosinophils and vascular proliferation, suggestive of Kimura’s disease. Diagnosis was confirmed by immunohistochemistry. She was treated with prednisolone at a dose of 1 mg per kg body weight per day for 3 weeks. Patient is symptomatically better and mass has not recurred after a period of 3 months.
