Marginal excision of squamous cell carcinomas of the hand.

Squamous cell carcinoma is the most common malignant tumor of the hand. Most hand surgery texts recommend wide excision with 1- to 2-cm margins. During a 10-year period, 32 patients with 35 lesions were treated with marginal surgical excision for squamous cell carcinoma of the hand. Greater potential morbidity and functional loss associated with wide excision was avoided in these patients. No recurrences were found at a mean follow-up of 31 months. One case of possible metastasis was identified. Three (8%) tumors required further treatment due to positive surgical margins. Marginal excision of squamous cell carcinoma of the hand is associated with a low rate of recurrence and metastasis. In addition, the potential for improved cosmesis and diminished morbidity when compared to older more radical surgical methods supports marginal excision for squamous cell carcinoma of the hand as a viable treatment technique.
