Central Trichoptilosis Associated with Trichorrhexis Nodosa and Pili Torti

A 12-year-old girl presented with a 1-week duration of hair loss associated with splitting of the hair ends and whitish dots on the occipital hairs. On microscopic examination, a longitudinal splitting of the hair shaft with reconstitution of the normal hair distal to the fracture, nodular swellings, with the appearance of broomsticks pushed into one another, at the site of whitish swellings, and the flattening and twisting of the hair shaft around the long axis were demonstrated.

Minor trauma to injury-prone hair is a common cause of hair shaft defects, however the reports with the combined conditions are insufficient in the literature. We describe a patient with central trichoptilosis associated with localized trichorrhexis nodosa and pili torti.
