Granulomatous mastitis is a rare breast disease that is categorized as a benign tumor with chronic inflammation. Since the cause of the chronic inflammation is usually unknown, it is sometimes called idiopathic granulomatous mastitis (IGM). Although imaging modalities, such as ultrasound, magnetic resonance imaging and mammography can detect tumors, they are sometimes unable to differentiate between benign and malignant tumors. In such cases, biopsy is needed to make a correct diagnosis. We experienced three cases of IGM after breast conserving surgery in breast cancer patients in whom we needed to rule out recurrence of breast cancer. In our cases, tumorectomy was performed in two cases for pathological diagnosis, since neither biopsy nor cytology was able to reveal a conclusive pathological diagnosis. Our management of these three cases might suggest the appropriate management of granulomatous tumors after breast conserving surgery in breast cancer survivors.
肉芽肿性乳腺炎是一种罕见的乳腺疾病，被归类为伴有慢性炎症的良性肿瘤。由于慢性炎症的病因通常不明，它有时被称为特发性肉芽肿性乳腺炎（IGM）。尽管超声、磁共振成像和乳腺X线摄影等影像学检查手段能够检测出肿瘤，但有时无法区分良性和恶性肿瘤。在这种情况下，需要进行活检以做出正确诊断。我们遇到了3例乳腺癌患者保乳手术后发生IGM的病例，在这些病例中我们需要排除乳腺癌复发。在我们的病例中，有2例进行了肿瘤切除术以进行病理诊断，因为活检和细胞学检查均未能得出确切的病理诊断。我们对这3例病例的处理可能为乳腺癌幸存者保乳手术后肉芽肿性肿瘤的适当处理提供了参考。
