Treatment of subungual myxoma preserving the nail matrix: a case report.

Subungual myxomas are uncommon, benign, expansile lesions that club the fingertip. Traditionally the nail matrix is incised, which results in permanent nail deformity. This report describes a midlateral approach that not only spares the nail apparatus but demonstrates that the nail can remodel even if a void is left under the nail matrix after excision of the tumor. The histologic examination of the tumor is described.
