Abstract

Accessory tragus (AT) is a congenital pedunculated or sessile, skin-colored papule or nodule, most often unilateral and solitary.e papule size is usually 3-5 mm and might be covered with vellus hair.Diagnosis is based on the age of onset, the clinical appearance of the lesion, and the characteristic anatomical location anterior to the tragus.However, uncommonly, accessory tragi may appear at unusual sites. 1,221-year-old male presented with a solitary, roughly spherical, 6 4 mm, soft, and skin-colored mass with a short pedicle located on the left nasal vestibule since birth [Figure 1a].ere was no history of consanguinity nor family history of similar cases.e patient was otherwise healthy without any system abnormalities.e patient wanted to remove the lesion for cosmetic purposes; however, he refused complete surgical excision, so the lesion was shaved by a scalpel, followed by cauterization of the base [Figure 1b], and then sent for histopathologic examination that revealed undulated epidermis with basket-weave hyperkeratosis, mild papillomatosis, and focal increase in basal melanin.e dermis showed loose collagen bundles and fat lobules occupying the central core [Figure 1c].Based on history and clinicopathological findings, the diagnosis was AT.
