Granulomatous mastitis (GM) in accessory breast tissue is rare. The present study aimed to report a rare case of GM in accessory breast tissue. A 39-year-old female patient presented with right axillary discomfort and swelling for ~5 days. On clinical examination, a tender, firm lump was detected in the right axillary region. The ultrasound showed diffuse parenchymal heterogeneity and surrounding edema in the right accessory breast associated with reactive axillary lymph nodes. Following unresponsiveness to conservative treatment, a surgical procedure was performed in the form of an excisional biopsy and the lesion was diagnosed as GM. During the six-month follow-up, there were no recurrences. The exact cause of GM remains uncertain and the etiology within accessory breast tissue is even less understood. Proposed mechanisms suggest that it may result from an exaggerated immune response triggered by various factors, such as infection, autoimmunity or hormonal fluctuations. GM in accessory breast tissue is a rare and challenging clinical condition to be diagnosed. Due to the rarity of this condition, it highlights the importance of including GM in the differential diagnosis of axillary masses.
副乳腺组织中的肉芽肿性乳腺炎（GM）较为罕见。本研究旨在报告一例副乳腺组织中GM的罕见病例。一名39岁女性患者出现右侧腋窝不适及肿胀约5天。临床检查时，在右侧腋窝区域发现一个压痛、质地坚硬的肿块。超声显示右侧副乳腺实质弥漫性不均匀，伴有周围水肿及反应性腋窝淋巴结。保守治疗无效后，进行了切除活检手术，病变被诊断为GM。在六个月的随访期间，无复发情况。GM的确切病因仍不确定，副乳腺组织内的病因更是知之甚少。提出的机制表明，它可能是由各种因素引发的过度免疫反应导致的，如感染、自身免疫或激素波动。副乳腺组织中的GM是一种罕见且具有挑战性的临床病症，难以诊断。由于这种病症罕见，凸显了在腋窝肿块鉴别诊断中纳入GM的重要性。
