Abstract
Fibromatosis colli is a rare, benign, cervical fibrous tumor observed in neonates and called sternocleidomastoid tumor of infancy. It typically presents as a palpable mass in the anterior part of the sternocleidomastoid muscle that is not present at birth but appears within the first weeks of life. Its etiology remains poorly understood, and most of the patients have a history of abnormal fetal head position and/or birth trauma. In this case study, we report a case of fibromatosis colli, diagnosed using ultrasonography and treated with physiotherapy. We emphasize that we should be aware of this clinical entity in the differential diagnosis of neck mass in neonates to prevent unnecessary investigations and refer them to physiotherapy.
