title: Schimmelpenning-Feuerstein-Mims syndrome with hypophosphatemic rickets.
abstract: The Schimmelpenning-Feuerstein-Mims syndrome (SFM syndrome) is a rare and variable multisystem defect consisting of congenital, extensive linear nevus sebaceus and associated abnormalities in different neuroectodermal organ systems. We present the history of a 52-year-old female patient with disproportionate hyposomia and asymmetric constitution. From birth she suffered from a right-sided, extensive nevus sebaceus following Blaschko's lines extending on the scalp, neck, right arm and trunk. At the age of 5 years, she developed a generalized growth retardation, along with deformations of bones. At the age of 11, hypophosphatemic rickets was diagnosed causing this growth retardation. Moreover, the patient developed a precocious puberty at the age of 9 years. When we saw the patient 40 years after the diagnosis had been made, phosphaturia had returned to normal. Specific therapy of hypophosphatemic rickets is straightforward and efficient in preventing late complications like growth retardation. We suggest to conduct appropriate laboratory tests in early childhood in patients with an extensive systematized sebaceous nevus or with additional signs of growth retardation or skeletal involvement, in order to exclude hypophosphatemic rickets associated with SFM syndrome.
