[Isolated macrodactyly or extremely circumscribed Proteus syndrome?].

We report on two unrelated female patients with unilateral macrodactyly of the 1st and 2nd toes and of the 3rd, 4th, and 5th toes, respectively. In addition, they had a local plantar soft tissue lump and radiographically abnormally broad phalanges of the affected toes. These clinical manifestations may represent either an isolated macrodactyly or an extremely localized form of Proteus syndrome.
