We report a case of localized TN in a 37-year-old male. He had an ovoid hair patch with multiple small white-gray dotted and stubby hairs localized to the right occipital scalp.

TN is known to be the commonest of all hair shaft anomalies (Price, 1975). However TN is rarely reported, and there have been only four reports in Korean dermatological literature, to our knowledge, which might be due to underdiagnosis of this disorder. We postulated that diagnostic difficulty lies in the discrepancy between terminology and gross morphological findings.
