Pachyonychia congenita tarda: A rare case report

Abstract

Pachyonychia congenita is a rare, but well-characterized autosomal dominant disorder of keratinization. It usually begins within the first few months of life. Here, we are presenting a rare case, which started at the age of 10 years of life and is known as pachyonychia congenita tarda. The case is being reported for its rarer occurrence as the patient had oral leukokeratosis and angular cheilosis present in the same type of the syndrome (Jadassohn-Lewandowsky syndrome), which is still uncommon.
