Malignant fibrous histiocytoma (MFH) of bones in the hand has rarely been reported. A case of MFH involving a metacarpal bone is reported. This case was a 46-year-old female with a firm lump of her right hand. The tumor originated in the second metacarpal bone widely invaded to the surrounding soft tissue. The extent of the tumor involvement, especially in the soft tissue was clearly defined with magnetic resonance imaging (MRI). Radical resection was performed with a below-elbow amputation according to the Enneking surgical staging system (SSS). One and a half years later she has no evidence of local recurrence or metastasis. Although the SSS is useful in deciding the operative method for malignant bone tumors, further local concept should be added to maintain function of the hand.
