Is keratosis punctata of the palmar creases rare?
We determined the prevalence of keratosis punctata of the palmar creases (KPPC) in 5000 individuals. The group screened included patients, visitors and children. Fifteen (0.3%) cases were discovered to have characteristic KPPC lesions. The patients were mainly young with a male predominance (14M : 1F). The lesions in almost all cases were asymptomatic. No predisposing factors could be ascertained by history. Histopathologically, the lesions consisted of focal hyperkeratosis, and an epidermal depression corresponding to the pits. Special stains did not reveal any dermal components in the keratin masses. On comparing our findings with those reported earlier it appears that KPPC is not so rare as believed.
