Pacinian neuromas and neurofibromas of the hands and fingers: a systematic review

Abstract

Tumours involving Pacinian corpuscles are rare. The literature identifies two main pathological disorders: the Pacinian corpuscle neuroma or hyperplasia and the Pacinian corpuscle neurofibroma. Published data are confusing and at times conflicting. This systematic review summarizes the available data in order to support clinicians in the differential diagnosis with other tumours responsible for unclear symptoms in the hands and fingers. We identified 67 pertinent articles. Although some similarities have been described, the two tumours have relevant differences, specifically when comparing age of the patient, location, symptoms, characteristic of a mass, and aetiology. All these factors should be taken into account in order to improve diagnostic accuracy. Despite the low incidence of unsuccessful surgeries, extraordinary measures are occasionally necessary to achieve complete resolution of symptoms.
