Macrodactyly: report of eight cases and review of the literature.
Congenital enlargement of one or several digits of the hands or feet (macrodactyly) is a rare disorder. A considerable proportion of the patients with this condition are referred to dermatology departments. The majority of the cases reported in the literature represent hamartomas with combined hypertrophy of several, predominantly lipomatous, soft tissue components and overgrowth of bone. The differential diagnosis includes Klippel-Trenaunay-Weber syndrome, neurofibromatosis, Milroy disease, and Proteus syndrome. We describe eight cases of congenital macrodactyly, discuss the findings, and propose a simple clinicopathologic terminology.
