Fibrous dysplasias are developmental bone disorders in which the medullary cavity is replaced by fibrous tissue. It can be monostotic involving a single bone or polyostotic involving multiple bones. Unlike the monostotic type, the polyostotic type of fibrous dysplasia is associated with non skeletal manifestations like cafĂ© au lait macule and/or endocrine hyperfunction. The presence of endocrine involvement differentiates McCune Albright syndrome from Jaffe Lichtenstein syndrome. We hereby report a case of an 11-yearold male child presenting with polyostotic type of fibrous dysplasia involving bilateral femurs with cafĂ© au lait macule having no endocrine disease consistent with the diagnosis of Jaffe Lichtenstein disease. He also had unilateral absent testis which is rarely reported in this syndrome.
