title: [A twelve-year-old teenager with bone pain and white papules].
abstract: Here we present a case report in which a teenager, with papules on the arm and back since the infancy, complained of back and right knee pain at the age of 12 years. The radiological examination led to the diagnosis of osteopoikilosis and melorheostosis. The Buschke-Ollendorff syndrome (BOS) associates osteopoikilosis (asymptomatic bone dysplasia) and disseminated dermatofibrosis. The BOS is rare, and its association with melorheostosis (another bone dysplasia in which pain and deformity may occur) makes the prognosis uncertain. This case report highlights the diagnosis problems related with bone pain in paediatrics. The purpose of this manuscript is to present the characteristics of two bone dysplasias: osteopoikilosis and melorheostosis, and to discuss the involvement of each one in the clinical picture of our patient.
