Bilateral accessory tragi on the suprasternal region


Bilateral accessory tragi on the suprasternal region. J Dermatol. 1997 Aug;24(8):543-5.

We report a 25-year-old man who had two protruding firm masses on his suprasternal region. These lesions were present at birth without any family history. He had no other subjective symptoms. In a histological specimen, there were numerous unevenly distributed telogen follicles that contained vellus hairs. Beneath a relatively narrow zone of fibrovascular tissue, lobules of fat with a central core of cartilage were seen. The mass was totally excised; during the follow-up period, there was no evidence of recurrence. The tragus derives from the first branchial arch. The accessory tragus can be found along the entire course of embryonic migration. It is usually located unilaterally in the preauricular region. To our knowledge, bilateral development on the suprasternal region has not been previously reported.
