Metachondromatosis: Clinical and radiological diagnosis and differential diagnosis

Abstract

The clinical case of a 9-year-old patient derived from Orthopedics to the Institute of Genetics at Universidad Nacional de Colombia due to a longstanding medical history of multiple bony outgrowths that required surgical management without etiologic diagnosis is presented in this paper. A possible diagnosis of metachondromatosis is suggested based on the clinical course, the family history, and the findings of the biopsy and regular growth parameters. On the other hand, differential diagnoses were compared taking into account the most common enchondromatosis type, based on data obtained during physical examination, radiological signs and other variables. This comparison was grounded on the review of existing literature on this type of entities.
