[Primary malignant schwannoma of the hand. Apropos of a case. Review of the literature].

Primary malignant tumours of nerves stemming from Schwann cells are exceptional. One case of malignant schwannoma of a distal collateral nerve is reported. It would appear to be the first case. The elements of the histological diagnosis are recalled and the rules for treatment are advanced: wide excision involving, in this case, phalangeal amputation with a satisfactory result after one and a half years, with no local or loco-regional recurrence.
