Benign tumors of the hand may be categorized using the different anatomic subunits of the hand. Each subunit has potential for disease processes and abnormal growth. Notably, the musculoskeletal, vascular, osseous, perionychial, cutaneous, and soft tissue elements can develop benign lesions that may manifest as localized masses of the hand. Excluding cutaneous malignancy, 95% of tumors of the hand are benign. The nonneoplastic ganglion is probably the most common mass found on the hand and wrist. Some benign growths may not need excision (Athanasian, 1993). Following ganglions, inclusion cysts, warts, giant cell tumors, granulomas, and hemangiomas follow in frequency. This article outlines each of the subunits and discusses benign growths that may exist in each anatomic structure.
