title: Hypophosphatemic rickets associated with giant hairy nevus.
abstract: The association of multisystem pathologic conditions and epidermal nevi, known as the epidermal nevus syndrome, includes disorders of bone, central nervous system, eye, kidney, vasculature and skin. Rarely, congenital nevomelanocytic nevus also known as hairy nevus has also been reported in association with hypophosphatemic rickets. Studies suggest that phosphaturia, caused by circulating factors, called "phosphatonins" may be secreted by an epidermal or hairy nevus. We report here, a rare case of hypophosphatemic rickets associated with a giant hairy nevus in a 10-year-old boy.
