nerve sheath myxoma

(redirected from plexiform myxoma)

nerve sheath myxoma

A benign, slow-growing peripheral nerve tumour averaging 1.5 cm in greatest dimension, which affects young adults (median age 35) and which arises in the dermis and/or subcutis of the extremities, especially of the hands and fingers, soft tissues, and within the spine. Recurrence is common when managed by simple excision. Prudence requires wide margins of grossly uninvolved tissue.
