title: Peripheral nerve mucoid degeneration of the upper extremity.
abstract: Peripheral nerve mucoid degeneration of the upper extremity is an extremely rare entity. Four new cases encountered in a 14-year period are added to the 10 cases reported in the world literature. Usually affecting males in their forties, it is heralded by an entrapement type syndrome. Pain, paresthesias, paralysis, and possible palpability, succinctly summarizes the order and frequency of the appearance of the differential diagnostic symptoms and signs. Soft part imaging may aid in the preoperative diagnosis. Therapeutically, conservative neurolysis, pertinent arcade sectioning, prudent neural dissection, partial pseudocyst wall excision, and content drainage all under optical enlargement is the treatment of choice. There are no recurrences with this treatment; however, the functional results depend on early diagnosis and surgical intervention before neural fiber destruction is complete.
