The clinical and histopathologic features of accessory tragi from 55 patients were analyzed. On both clinical and histologic grounds, accessory tragi were often mistaken for skin tags, fibromas, or papillomas. The lesions were present at birth and appeared as solitary or multiple papules located between the pretragal and sternoclavicular regions. Histologically, there were numerous unevenly spaced telogen follicles that contained vellus hairs. Beneath a relatively narrow zone of fibro-vascular tissue there were usually abundant lobules of fat and a central core of cartilage. Even In lesions without cartilage, an objective histologic diagnosis could be suggested and the condition differentiated from cutaneous papillomas, which contain no epidermal adnexa.
