Abstract
|
|
|
Trichorrhexis nodosa (TN) is the most common hair shaft anomaly and is caused by physical or chemical trauma.
It is characterized by nodular swellings of the hair shaft accompanied by frayed fibers and loss of cuticle. The fibers
then fracture and the shaft breaks with the resultant appearance of a splayed paintbrush or fan-like array. Trichorrhexis nodosa is classified into congenital TN and acquired TN. Acquired TN is further classified into three groups, acquired localized TN, acquired proximal TN, and acquired distal TN. To date, no case of distal trichorrhexis nodosa has been reported in Korean dermatologic literature. We herein report a case of acquired distal trichorrhexis nodosa in a 12-year-old boy.
