Tumorlike lesions and benign tumors of the hand and wrist.

A broad spectrum of tumorlike lesions and neoplasms can occur in the hand and wrist, although with somewhat less frequency than in other parts of the body. A thorough understanding of the differential diagnosis of these lesions and a comprehensive strategy for evaluation are central for effective care. Plain radiographs are diagnostic for most bony lesions, whereas magnetic resonance imaging may be necessary to help differentiate a benign soft-tissue lesion from the rare malignant neoplasm. In spite of the complex anatomy, adherence to proper oncologic principles most often will lead to a satisfactory outcome.
