Exophytic Nodule on the Helix

A 13-year-old boy presented for surgical removal of a “cyst” on his left ear, which had been present since birth. He reported that it had initially resembled a small red bump but had grown over the last 10 years and occasionally discharged a thick, white material. The patient carried a diagnosis of attention-deficit hyperactivity disorder and depression, but had no history of developmental or growth delay and had normal renal function. Physical examination revealed a 1-cm nontender, exophytic, firm nodule on the left helix (Fig. 1). An excision was performed. Histologic sections were stained with hematoxylin and eosin and are shown in Figs. 2 and 3.
