 note = {Inflammatory pseudotumor is a benign reactive lesion which forms due to diverse tissue responses of inflammatory cells and mesenchymal cells. It can occur in various organs of the body but rarely in the breast. We report a case of inflammatory pseudotumor of the breast after augmentation mammoplasty. The patient was a 78-year-old woman who noticed a mass in her right breast in July 2012. She had a history of augmentation mammoplasty at age 24 years. She was referred to our hospital for thorough examination. A 3-cm immovable induration was palpated in the upper lesion of the right breast. Ultrasound examination revealed a hypoechoic mass at the same site. The mass was 2.9×1.7 cm with irregular, ill-defined borders. Mammography revealed some areas of elevated density with coarse, lucent-centered calcifications in bilateral breasts but no clear findings of malignancy. Core needle biopsy of this site revealed marked fibrous hyperplasia and proliferation of fibroblast-like spindle cells. Infiltration of neutrophils and plasma cells was observed in the stroma. There were spindle cells with no atypia and scarce mitotic figures. Thus, the patient was diagnosed with inflammatory pseudotumor. The patient received only follow-up observation without surgical resection as per the patient's wishes. There has not been any change as of May 2013., Case Report},
