FIBROUS STERNOMASTOID TUMOR OF INFANCY

[摘要] A case of sternomastoid tumor of infancy is described which presented clinically as a neck mass without torticollis and simulated a neoplasm.Four aspects of the problem are discussed: (1) the relationship of tumor and torticollis; (2) the etiology and pathogenesis; (3) the differential diagnosis from sarcoma; and (4) the treatment.Prophylactic resection of the mass to exclude a possible malignant tumor or to prevent the subsequent development of torticollis, is not justified, since in about 80% of cases spontaneous regression occurs without sequelae.The institution of passive neck exercises over a period of several months during and following degression of the mass may contribute to a decreased incidence of deformities.
