Localized multiple neurilemmomas of the lower extremity.

A neurilemmoma usually presents as a solitary subcutaneous tumor adherent to a peripheral nerve. Multiple localized neurilemmomas may occur as an isolated cutaneous finding or as part of the syndrome of neurilemmomatosis. We report a case of multiple neurilemmomas appearing on an extremity after trauma. The multiplicity and localization of the tumors are rare and illustrate that neurilemmomas are not invariably solitary tumors and that their distribution can be regional. We review the previously reported cases of multiple neurilemmomas and review the characteristics that help the clinician to differentiate between multiple localized neurilemmomas and neurilemmomatosis.
