Tumors of peripheral nerves
Neurinoma (neuroma, schwannoma) originating from Schwann cells, are benign tumors of various sizes - thick, fusiform, or rounded knots that are located along the nerve trunk. Neurinoma clinically expressed most painful irritation. Rarely neurinoma tumors (neuroma, schwannoma) are accompanied by clinical signs of loss of sensory and motor nerve function or a combination of these symptoms. Palpation of the tumor (neuroma, schwannoma) irradiation typically causes pain and paresthesias along the branching of the nerve at the periphery.
Nerve tumors surgical removal treatment is reduced to the extirpation of neurinoma (schwannoma) dissected longitudinally fibrous capsule formed by connective tissue layers of nerves, with maximum effort not to damage the passing in the interior of the capsule nerve bundles. Typically, the nerve tumor (neuroma, schwannoma) is distinguished by blunt, without much difficulty, and only rarely have to resort to resection of the nerve with the tumor and subsequent suture of the nerve.
Malignant sarcomatous tumor of the nerve with infiltrative rapid growth to be wide resection, along with the surrounding tissues. It is sometimes necessary to resort to amputation, but in the case of such tactics frequently observed metastasis of sarcomatous tumors of the nerve.
Melanoma (pigmented nevus) refers to a group of tumors of the nerve endings, is derived from Schwann cells, sensory cells in the skin. Melanoma (pigmented nevus) may take the form of birthmark (nevus) or extensive flat or papillary tumor of brown. In malignant melanoma shows a radical resection of the nerve with all the regional lymph nodes in combination with radiation therapy.
In multiple neurofibromatosis, characterized by the development of many tumors of various sizes along nerve trunks, do not usually cause serious functional disorders, indications for surgical intervention occur only in cases where a single node begins to cause pain or a very large site puts pressure on the adjacent formation.
Recklinghausen's disease, or neurofibromatosis, is characterized by multiple intradermal nodules of varying size and tumors that develop in thin nerve stem and their cutaneous branches (neyrofibrom and neurinomas), pigmented spots on the skin of a light coffee-colored, small hemangiomas, and lymphangitis. Occasionally when Reklingauzena disease (neurofibromatosis) are observed neurofibromas and neurinomas of the cranial nerves (auditory, trigeminal, etc.) are also observed neurofibromas of spinal roots, causing compression of the spinal cord and brain, and then there are indications for surgical intervention in Reklingauzena disease (neurofibromatosis).
Among the tumors of the autonomic nervous system distinguish benign (ganglionevromy), relatively benign (ganglionevroblastomy, pheochromocytoma or paragangliomy) and malignant (neuroblastoma). Depending on klinicheksih manifestations of tumors of the autonomic nervous system will be constructed treatment tactics.
