A 68 year old male agriculturist presented with asymptomatic growth over his right ear for the past three years. The growth was insidious in onset and started as a small firm pigmented papule three years back. The lesion was aymptomatic and gradually increased in size. He gives history of occasional bleeding on touch. No history of similar skin lesion in the past or in family members. No history of any type of ear trauma or ear surgery in the past. Examination revealed 3 × 4 cm, mulberry like pigmented growth [Figure 1], soft to firm in consistency, mobile with no tenderness on palpation seen in the groove between helix and anti-helix of right ear. Excission biopsy was done and histopathology of the tumor showed hyperkeratosis, parakeratosis, acanthosis and papillomatosis with sharp horizontal demarcation from the dermis. The epidermal cells are composed of squamous and basaloid cells with abundant melanin pigment and keratohyaline granules. Squamous eddies and several horncysts are seen [Figure 2] and [Figure 3]. Non-specific lymphocyitc inflammatory infiltrate was seen in upper dermis.
