Localized multinucleate distal subungual keratosis.
Isolated distal subungual keratosis refers to a clinical monomorphic lesion involving one digit, but presenting different histological patterns. Among these, in four similar cases, we have observed the presence of multinucleate cells in localized distal subungual keratosis without an intervening granular layer, and without any clinical evidence of Darier's disease. To our knowledge, this constellation of anatomical and clinical features has not been reported previously.
