Trevor's disease is a rare abnormality characterized by aberrant osteocartilaginous growth from an epiphysis. We describe six new cases from our institution. A patient with isolated tibial tuberosity involvement is described for the first time. Each patient was classified according to Azouz into localized (three), classical (two) and generalized (one) form. We recommend that parents be counseled regarding the progressive nature of this disorder owing to the chance of worsening deformity with surgical excision alone, and the need to be followed until skeletal maturity.
