title: Focal subungual warty dyskeratoma.
abstract: Warty dyskeratoma is described in an unusual location. Clinically it appeared as a longitudinal reddish ridge bordered on each side by brown splinter haemorrhages forming a nearly continuous line. The free margin of the nail plate was slightly fissured distal to the red band. In the distal groove, histology showed deep epithelial digitations which lined a crater-like area. Numerous multinucleate giant cells, marked dyskeratosis and acantholytic suprabasal clefts were visible inside this tumour resembling Darier's nail disease.
