Abstract

Nodular fasciitis is a benign fibroblastic proliferation rarely reported in the breast. We report the case of a 55-year-old woman who presented with imaging findings that resembled a malignancy. Mammography revealed an isodense nodule with partially indistinct margin in the right breast, showing the abnormality score 75% on artificial intelligence. Ultrasonography revealed an oval hypoechoic nodule with microlobulated margin, echogenic halo, increased blood flow, and soft elasticity. After core needle biopsy and excision, nodular fasciitis was diagnosed. Although nodular fasciitis of the breast is rare, it may mimic malignancy; therefore, it should be considered as a differential diagnosis to prevent unnecessary intervention.
