Abstract
Papillon–Lefèvre syndrome (PLS) is a rare autosomal recessive disorder characterized
by early loss of teeth with hyperkeratosis of the palms and soles. Congenital insensitivity
to pain with anhidrosis (CIPA) is a disorder of decreased pain sensation, decreased
sweating, recurrent infections, and fever. Here, we report a 5-year-old girl born
to consanguineous parents with a family history of a similarly affected sibling. The
girl presented with early loss of teeth and palmoplantar hyperkeratosis, hence, provisionally
diagnosed as PLS. Further clinical examination and detailed history taking shifted
the diagnosis to CIPA. CIPA could be misdiagnosed as PLS. Congenital insensitivity
to pain with anhidrosis, although rare, should be considered in the differential diagnosis
of PLS.
