Peripheral nerve tumours: 30-year experience in the surgical treatment.
Peripheral nerve tumours are relatively rare type of soft tissue tumours. The aim of this work is to present our experience with surgical treatment of this type of lesions. Clinical material consists of 94 patients (56 females, 38 males), in whom 101 tumours deriving from peripheral nervous system were removed. The patients underwent surgical treatment between 1983 and 2012. Tumours occurred mainly in the upper extremity (72 tumours), less often in the lower extremity (25 tumours). Lesions developed in major peripheral nerves (51 tumours) and small nerve branches (50 tumours). The most common symptoms reported before surgery included presence of tumour mass (100 %), positive Hoffmann-Tinel sign (95.6 %) and paraesthesia (93.4 %). Less often sensory deficit (89.1 %) and pain (71.7 %) were observed. Motor deficit was the least common manifestation (41.3 %). Benign tumours prevailed in presented material (94 tumours). In 7 cases, malignant peripheral nerve sheath tumour (MPNST) was identified. As a result of surgical treatment in the group of tumours deriving from major peripheral nerves, in 87.8 % of the patients, pain relief was achieved; in 84 %, Hoffmann-Tinel sign was negative; and in 79 %, paraesthesia resolved. Sensory function improvement was observed in 51.2 % of the patients while motor function improved in 26.3 % of the patients. None of the patients experienced tumour relapse. In the group of tumours deriving from small nerve branches, 47 patients had no signs of tumour recurrence. One female patient diagnosed with MPNST suffered a relapse. Obtaining satisfactory results of peripheral nerve tumour treatment requires both careful differential diagnosis and well thought-out strategy at every stage of therapeutic management.
