A Case of Subepidermal Calcified Nodule in Auricle

Subepidermal calcified nodule, also called as cutaneous calculi, is a rare form of calcinosis cutis, which is not associated with biochemical abnormalities, or other dermatologic disorder or systemic illness. It occurs on the face and ear of children, and is asymptomatic. It usually presents as a solitary verrucous nodule and histologically shows as basophilic granules and masses in the dermis. We experienced one case of subepidermal calcified nodule in a 9-year-old boy with auricular mass. He did not have any other dermatologic disorder or systemic illnesses. Physical examination showed a 1.5×3 cm sized, non-tender, hard, fixed mass on left helix. It was surgically excised. It was finally reported as calcinosis cutis. We report it with a review of the current literature. (Korean J Otorhinolaryngol-Head Neck Surg 2007;50:947-9)
