Occurrence of two interdigital neuromas in one foot

In a series of 89 neurectomies, the occurrence of a second primary interdigital neuroma was less than 4%. The clinical presentation and results of surgery were similar to those of a single interdigital neuroma. Two of five patients with a suspected second neuroma in the same foot did not have this entity, but instead had had the incorrect interspace operated on by the previous surgeon. The entity of a second neuroma is truly rare, especially if careful evaluation for correct diagnosis and interspace is done.
