Median canaliform nail dystrophy is a clinically characteristic change in theĀ nail plateĀ presenting as aĀ midlineĀ longitudinal furrow or split āš”ļø and also transverse ridges angled backwards in a fir-tree pattern. ItĀ can affect all age groups, including children. Familial cases have been reported. It affects men and women equally.

Causes of Median Canaliform Nail Dystrophy

It is an acquired nail change believed to be due to microtrauma of the nail matrix, resulting in a temporary defect inĀ keratinocyteĀ adhesion that affects tensile strength of the nail plate.

The majority of cases appear to be sporadic orĀ idiopathic. There have been rare reports withĀ systemicĀ isotretinoin use.

A similar but distinct nail dystrophy can be caused by habitual picking of theĀ nail foldĀ (habit-ticĀ deformity) and there have been very rare reports of the two conditions co-existing. Some have postulated they are variants of the same disorder.

Clinical Features of Median Canaliform Nail Dystrophy

This condition most commonly involves both thumbnails, although it can be unilateral. Other fingernails and toenails also affect. The longitudinal split āš”ļø extends from theĀ proximalĀ nailfold to the free edge of the nail. It is usually in the midline but may be off-centre. MacrolunulaeĀ (larger than normalĀ lunulae) are frequently observed in the affectedĀ nails.
