Abstract
Macrodystrophia lipomatosa is a rare cause of congenital macrodactyly, characterized
by progressive proliferation of all mesenchymal elements, with a disproportionate
increase in fibroadipose tissue. This developmental anomaly is reportedly more common
in the foot than in the hand, with a predilection for the plantar and median nerve
distribution. We present two cases of MDL of the hand, one of which had an unusual
nerve territory distribution, making clinical diagnosis difficult. Preoperative diagnosis
was however made on the basis of radiography and MRI and was later confirmed on surgery.
