Management of a large lesion of monostotic fibrous dysplasia with possible malignant transformation

Abstract

A 50-year-old male presented with a large mass involving the left third rib following more than 30 years of a slow growing asymptomatic swelling in the chest wall. Computerised tomography (CT) scan showed a mass 7 × 10 cm expanding the left third rib and having a sclerotic outer margin which showed discontinuity and raising the possibility of malignancy arising in longstanding fibrous dysplasia (FD). Needle biopsy is confirmed fibrous dysplasia. Histological examination of the completely resected lesion confirmed the absence of malignancy. The patient made an uneventiful recovery. © 2008 Springer-Verlag.
