Massive congenital cervicofacial desmoid-type fibromatosis in a 5-month-old infant.

Desmoid-type fibromatosis (DF) is a borderline tumor of soft tissues that has low malignant potential but described as infiltrative, locally aggressive and rapidly growing. In the pediatric population, it occurs in the head and neck. Presentation varies based on tumor size and location. Despite the high recurrence rate, surgical excision remains the modality of choice with. Here, we report a case of a 5-month-old boy, with extensive head and neck DF that was managed twice with conservative debulking surgery through a combined transoral-transcervical approach. On 2-year follow-up, he was gaining weight with no developmental delay and had no clinical evidence tumor regrowth.
