Two patients with compression neuropathy of the superficial radial nerve are presented.
Case 1: A 71 year-old female visited our clinic in November, 1995 with a one month history of pain in the dorsum of both hands.
Clinical examination revealed paresthsia on the radial half of the dorsum of her hand and tenderness on dorsal area of the distal forearm, where the superficial radial nerve pierced the deep fascia of the forearm. The patient was operated on after failure of conservative treatment for Cheiralgia Paresthetica.
At exploration a membranous tissue traversing over the nerve was seen and incised, and a shallow indentation was seen on the nerve under the membrane.
After the operation her pain disappeared and has not recurred.
Case 2: A 38 year-old male presented in 1991 with dysesthesia on the dorsum of his right hand and a tumor on the dorsum of his right forearm.
He also reported pain on the dorsal side of his right hand. Three years later he recognized a small tumor on the dorsal side of his right distal forearm and dysesthesia on the dorsum of his right hand. Examination revealed sensory loss limited to the area supplied by the superficial radial radial nerve and a tumor on the dorsal side of his right forearm.
Partial resection of the tumor and neurolysis was carried out, under the diagnosis of a compression neuropathy of the superficial radial nerve due to a forearm tumor.
The pathological diagnosis was a nalignant fibrous histiocytoma.
The patient's pain disappeared after the operation but recurred one month later. The patient died four months later due to lung metastasis.
