Misdiagnosis of plexiform neurofibroma of the medial plantar nerve: case report

Plexiform neurofibromas are benign tumors of the peripheral nerve. Diagnosis may be challenging, if they present mimicking other peripheral nerve pathologies. We report the case of a patient who had severe foot pain, which progressively hampered her walkingability, erroneously attributed to recurrent Morton’s neuroma. Diagnosis of plexiform neurofibroma ofher right medial plantar nerve was made 15 years after the appearance of symptoms. Pain and function recovered after radical neurotomy of the medial plantar nerve. A correct diagnosis is an essential starting point in the treatment of neurofibromas and a misdiagnosis may lead to an inappropriate treatment
