Cornu cutaneum is a relatively uncommon projectile, irregular, hyperkeratotic nodule that can be seen in places such as scalp, forehead, eyelids, ear, nose, lips, and upper extremities which are subjectable to sunlight. Treatment is surgery with radical margins. Excisional biopsy is enough for treatment of the lesion on head and face. However, there is only little literature about cornu cutaneum on the nasal vestibule. We present an 82-year-old male patient with a necrotic, irregular shaped lesion with pedicle on the left nasal vestibule excised and diagnosed as cornu cutaneum.
