Spiny keratoderma: The gritty tale

Abstract

Spiny keratoderma is a rare disease; first described by Brown as “punctuate keratoderma”. It is characterized by asymptomatic keratotic pin point papules over palms and soles, resembling the old fashioned music box spine. The spiny spicules are often misdiagnosed and has a very subtle histopathological difference from punctate porokeratosis. With only less than 40 cases reported worldwide, we report our case as the very few mentioned in Indian literature.
