Which physical examination finding may be noted in a patient with chondromyxoid fibroma?

• A. Heat around the lesion
• B. Palpable crepitus
• C. A palpable mass with a sclerotic appearance
• D. Skin changes overlying the lesion

Answer: (C)

The presence of a palpable mass with a sclerotic appearance is a key physical examination finding associated with chondromyxoid fibroma. This benign bone tumor typically occurs in the metaphysis of long bones and is characterized by its distinct histological features, which include myxoid, cartilaginous, and fibrous components. As the tumor develops, it can lead to the surrounding bone undergoing reactive changes, resulting in sclerosis. This bony reaction often manifests as a palpable mass upon examination. The sclerotic appearance indicates that there is increased bone density around the tumor, which may contribute to the palpable firmness of the lesion when assessed physically. Other findings such as heat around the lesion, palpable crepitus, or skin changes are not typical characteristics of chondromyxoid fibroma. Heat may suggest inflammation, crepitus is associated with joint pathology rather than a bone tumor, and skin changes are more related to soft tissue pathology, making the presence of a palpable mass with a sclerotic appearance the most accurate finding in this scenario.
