Nodular fasciitis of the chest: case report of a rare presentation.

Nodular fasciitis is a benign reactive proliferation that usually involves the deep fascia. The rapidly growing, the abundant cellularity, and the mitotic activity noted on histology can simulate an aggressive entity, such as sarcoma. We report an uncommon case of nodular fasciitis involved the chest wall of a thirteen boy and its management, emphasizing the need to consider this lesion in the differential diagnosis of pediatric soft tissue masses.
