Sternocleidomastoid tumor of infancy: two cases of an interesting entity

Sternocleidomastoid tumor of infancy (SCMTI), also known as fibromatosis co lli or muscular torticollis, is the most common cause of congenital tortico llis. It is present in approximately 0.4% of live births, and usually 90% o f patients will have a good prognosis if therapy is initiated and continued for the appropriate period of time. This paper presents two cases of SCMTI and explains the diagnostic modalities and treatment options for this enti ty. SCMTI should be diagnosed early in the infant's life, since early detec tion and initiation of conservative treatment leads to resolution of the di sease in the majority of patients.
