Giant elephantiasis neuromatosa in the setting of neurofibromatosis type 1: A case report.

ABSTRACT: Elephantiasis neuromatosa (EN) can arise from a plexiform neurofibroma of the superficial and deep nerves developing from a hyperproliferation of the perineural connective tissue infiltrating adjacent fat and muscles. To date, the clinical association between EN and neurofibromatosis type 1 (NF1) has been poorly defined, particularly with regard to the role of lymphatic alterations and the consequent lymphedema. The present study reports the clinical and biomolecular features of EN in a NF1 patient with the clear clinical diagnostic criteria of multiple cafè-au-lait macules, neurofibromas, EN, a positive family history and a novel NF1 germline c.1541_1542del mutation. Lymphoscintigraphy (LS) highlighted marked dermal backflow in the affected limb, hypertrophy of the ipsilateral inguinal an
