Benign nerve tumours of the hand (excluding wrist)

Hand tumours of neural origin are rare in clinical practice. The aim of this work is to present our experience in operative treatment of benign nerve tumours located in the hand. Special emphasis has been put on determining the occurrence rates of particular tumour types characterized by their unique histopathological patterns and describing detailed location of the lesions. The obtained results of treatment were assessed.

The study comprised of 26 patients, both female (19) and male (7). The mean age and age range of the female and male patients were 44.8 years (range, 21-73 years) and 39.6 years (range, 21-74 years), respectively. The patients underwent operative treatment for tumours of neurogenic origin located in the hand between the years 1990 and 2013. In total, 31 tumours in 26 patients were removed. The most common site of tumour origin was small cutaneous branches and only exceptionally the tumours arose from common digital nerves (2 patients). No patient was lost to postoperative follow-up. The shortest period of postoperative follow-up covered 1 year.

No tumour recurrence was detected during postoperative follow-up examinations. The patients reported neither pain nor presence of paraesthesias. Neurofibromas (17 tumours) predominated in the gathered clinical material, while the second most common group of tumours were schwannomas (12 tumours).

(1) Benign nerve tumours of the hand are rare. Neurofibromas and schwannomas predominate among them. Tumours having other histopathological patterns are extremely uncommon. (2) The prognosis after resection of benign nerve tumours located in the hand is good and the risk of postoperative complications and recurrence is low.
