Are You Confident of the Diagnosis? Nerve sheath myxomas (NSMs) are rare tumors of peripheral nerves. NSMs were once considered to be myxoid variants of neurothekeoma (NTKs), but recent data suggest they are distinct entities. Characteristic findings on physical examination NSMs typically present as slow-growing, solitary, superficial, multinodular masses from 0.5 to 2.0 cm with…
