Neurothekeoma, also known as nerve sheath myxoma, perineural myxoma and plexiform myxoma, is a rare benign neoplasm of presumed nerve sheath origin. This tumour typically presents as a slowly enlarging painless cutaneous swelling most commonly in female adolescents in the head and neck region or upper limb. Nerves in the dermis are more frequently involved than those in the subcutaneous tissue. It rarely affects subfascial peripheral nerves or the central nervous system. Of the 150 cases published since its first description in 1969, three cases involved deep peripheral nerves in the hand. To the best of our knowledge a neurothekeoma affecting a deep peripheral nerve of the lower limb has not been reported. We present such a case involving the sciatic nerve with significantly larger size compared with previously described cases.
