Is there a difference between habit tic and median canaliform nail dystrophy of Heller?

Type: article
Abstract: Heller’s Median canaliform nail dystrophy (MCD) and habit tic deformity (HTD) are often confused with each other, although there are distinct differences between the two conditions. MCD is characterised by a median break in the nail and obliquely-proximally running furrows without a longitudinal depression. Signs of skin picking are lacking. HTD shows longitudinal shallow and wide depression with innumerable short transverse lines, due to repeated pressure on the nail matrix as a result of repeated pushing of the proximal nail fold’s free margin back.
