Nodular fasciitis is a benign, reactive, tumor-like lesion composed of fibroblasts and myofibroblasts. It typically occurs in the extremities and the trunk. Head and neck localization is 13-20%. As it grows rapidly, clinicians frequently misdiagnose it as an aggressive or a malignant lesion. Some lesions show moderate cellularity, mild cellular atypia, and mitosis histologically causing patholo...

Nodular fasciitis (NF), a benign proliferation of fibroblasts, commonly presents as a solitary, well-circumscribed, rapidly growing soft tissue mass. It is most commonly located in the upper extremities, particularly on the volar aspect of the elbow, and on the chest and trunk. In adults, NF is rarely found in the head and neck region. Although benign, it can often be confused with a more malig...
