FOCAL SUBUNGUAL WARTY DYSKERATOMA

Warty dyskeratoma is described in an unusual location. Clinically it a ppeared as a longitudinal reddish ridge bordered on each side by brown splinter haemorrhages forming a nearly continuous line. The free marg in 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 d yskeratosis and acantholytic suprabasal clefts were visible inside thi s tumour resembling Darier's nail disease.
