Macrodystrophia lipomatosa is a rare nonhereditary form of focal gigantism that is characterized by osseous and fibroadipose tissue overgrowth [1, 2]. This condition affects either the hand or foot, classically occurring in a median or plantar nerve distribution [1, 2]. Distal and volar digital involvement is typical (as in our case), and affected digit growth usually ceases after puberty . Although the radiographic findings of this condition are generally pathognomonic and further evaluation with MRI is usually not necessary, macrodactyly can be due to numerous other causes, including Proteus syndrome, neurofibromatosis, and a variety of vascular lesions [1, 2].
