Abstract
Peripheral nerve tumours (PNT) are rare lesions that are generally categorised as soft tissue tumours, so they are usually managed by a range of surgical disciplines such as plastic, orthopaedic and trauma surgery, dermatology, general surgery and neurosurgery. Appropriate knowledge of the therapeutic indication and surgical management are essential in order to avoid neurological deficit. This is a retrospective study of 66 tumour lesions in 64 patients, acquired from the joint experience of 2surgical teams specialised in peripheral nerve surgery. The most common location was the lower limb and upper limb with 48 tumour lesions. The most common pathological diagnosis was Schwannoma, accounting for 51.5%. Complete tumour resection was achieved in 81.8% of the lesions and always with neurophysiological stimulation and/or monitoring. The most common postsurgical complication was neuropathic pain and/or a transient sensory disorder in 15% of surgeries, with only one persistent motor deficit appearing in 2cases that required nerve graft reconstruction. Although the therapeutic management of benign tumours such as Schwannomas can be considered to be relatively simple thanks to the application of the basic concepts of peripheral nerve microsurgery, malignant tumors, despite being very rare, require multidisciplinary management. The option of pre-surgical biopsy remains a controversial issue and no consensus has been reached among the different authors. In our opinion, percutaneous biopsy is not necessary in most cases.
