Abstract

Seborrheic keratosis is common benign cutaneous tumour in the elderly which usually presents as pigmented lesion with stuck on appearance. It is seen on the head and neck region. Ear is an uncommon site for Seborrheic keratosis. Seborrheic keratosis is associated with sun- exposure, HPV and mutations in the FGFR3 and PIK3CA gene, but the pathophysiology is still not very clearly understood. We present a case in 60 years old lady who presented with a dark brown pigmented, cerebriform growth in the concha near the external auditory canal associated with reduced hearing and discharge on and off. Clinical suspicion was keratoacanthoma but the histopathological examination showed irritated and pigmented variant of Seborrheic keratosis. Seborrheic keratosis seldom needs to be treated since most of the patients are asymptomatic and get treated for cosmetic purpose but in this present case the patient was symptomatic, hence the mass was excised.
