Examination of tumor and tumor-like conditions of bone

Surgical pathology specimens composed of bone, ranging from core biopsy to limb amputation specimens, require special attention, processing, and often unique equipment. This readily translates into additional handling steps and time, especially when one factors in clinical correlation with the surgeon and radiologic review of all images with a knowledgeable musculoskeletal radiologist. When these factors are superimposed on the rarity of these lesions in routine practice, it is not surprising that most trainees, as well as seasoned pathologists, are wary of these lesions. In this report, we use a case of osteofibrous dysplasia (Campanacci's disease) to demonstrate the dissection of such a surgical specimen and complete the report with a brief discussion of the entity.
