Granular parakeratosis

This is a report of a 60 year-old black female patient presenting with pruritic brownish crusted plaques on both axillae of one month evolution. Histopathology revealed findings characteristic of axillary granular parakeratosis. This entity was first described by Northcutt et al in 1991. Since then, involvement of other intertriginous areas have also been reported. A review of the literature was performed and the term granular parakeratosis is suggested to emphasize its pathognomonic histopathologic features
