Schwanommas, or neurilemomas, are known as rare or frequent tumors from Schwann cells (glial cells found in the peripheral nervous system), and in most situations behave benignly. The case we present is illustrative of a rare pathology, a benign tumor that differs along the Schwannian lines, some may have not insignificant mitotic activity but their behavior is benign; however, these types of tumors usually appear in the deep soft tissues and only rarely involve the subcutaneous tissue. During this report we illustrate the case of a female patient of the 3rd decade of life, which presents a cervical tumor with growth for 3 years until the medical-surgical approach, subsequent to the onset of symptomatology, although without data of airway compromise, hemoadynamic state or neurological alterations, but if presenting significant pain and difficulty to cervical mobilization. Complementing with imaging studies who suggest ruling out gill cyst against pleomorphic adenoma. The treatment of choice is excision since usually the schwannoma displaces and compresses the residual nerve in its periphery, being able to be removed without affecting the nerve.in this case specifically speaking of direct affection to the vagus nerve (X pair) left hemilateral, dissecting and enucleate the tumor seeking to preserve the functions of the nerve already mentioned. subsequently patient presents data of Horner syndrome during the immediate postoperative and mediate with ptosis and enophthalmos, lasting with alterations that after two months remit favorably, without data of paralysis, alterations in the swallowing or dysphonia, only continuing with pain in temporary region to chewing.
