Histological diagnostic criteria for accessory tragi.
The histological features of accessory tragi from 13 patients were analyzed. All the lesions showed numerous tiny mature hair follicles in various phases, while the presence of cartilage was not essential. Of importance was the prominent connective tissue framework in the subcutaneous fat that seemed to be one of the diagnostic criteria for accessory tragi.
