Fibromatosis colli
Fibromatosis colli
Clinical features Fibromatosis colli is a rare condition seen only in infants and children. Most of the cases present within the first few weeks of life, with no sex predilection.1โ3 Typically, a mass involving the distal sternocleidomastoid muscle and measuring less than 3โฏcm in diameter is seen. The mass results in rotation of the head and torticollis. Lytic clavicular lesions have been reported.4 A rare case associated with overlying hypertrichosis has been described.5 Surgical treatment is required only in a small number of patients. The treatment of choice is physiotherapy. The majority of cases show spontaneous resolution.3,6
Differential diagnosis Distinction from Gardner fibroma may be very difficult. Nuclear accumulation of ฮฒ-catenin is seen in Gardner fibroma but any lesion with morphological features of nuchal-type fibroma should be considered Gardner-associated until clinical work-up proves otherwise. Desmoid fibromatosis may show focal areas resembling a nuchal fibroma but, in most areas, tumors are more cellular and show prominent infiltration of surrounding tissues.15
