Pseudocyst of the auricle: diagnosis and management with a punch biopsy.

A case of pseudocyst of the ear diagnosed and treated with a punch biopsy is reported. Pseudocyst of the ear is considered to be a benign, asymptomatic condition seen infrequently in clinical practice. Our patient is a 45-year-old white man who presented with a 5-month history of a painless nodule on his left auricle without any preceding history of trauma. Although many treatments have been reported, none appear satisfactory, and many surgical treatment modalities are cumbersome. This is the first report, to our knowledge, of a case of a pseudocyst of the ear confirmed and treated with a 3-mm punch biopsy of the inferior border of the pseudocyst, followed by a pressure bolster.
