The goal of this observational study is to investigate the disease progression rate and timing in patients with mild Non-Lactational Granulomatous Lobular / Periductal Mastitis (NL-GLM/PDM) during follow-up with observation alone strategy. The main questions it aims to answer are: What is the rate of disease progression in mild NL-GLM/PDM patients under observation, and what clinical and pathological factors are associated with this progression? Participants with diagnosis of mild NL-GLM/PDM will be monitored over a specified period, with data collected on their clinical outcomes and relevant factors influencing disease progression.

Non-Lactational Granulomatous Lobular Mastitis (NL-GLM) is an inflammatory disease of unknown etiology, characterized clinically by local breast masses, accompanied by redness and swelling of the overlying skin, sinus tract formation, and other symptoms. Currently, there is no universally accepted standard treatment for this condition; previous expert consensus or practice guidelines have mostly recommended systemic glucocorticoid therapy as the primary treatment approach. Our team's preliminary research has confirmed that local glucocorticoid injection achieves efficacy equivalent to systemic administration but with better safety, making it a first-line treatment option for NL-GLM. However, in our preliminary studies and literature reports, we found that some patients still exhibit glucocorticoid dependence or resistance (i.e., refractory NL-GLM) after receiving either local or systemic glucocorticoid therapy. The lack of high-quality evidence to support subsequent-line treatments has become a major bottleneck in clinical management. Additionally, some patients cannot tolerate glucocorticoid therapy due to its adverse effects. Research has shown that the IL-6 inflammatory pathway is significantly activated in the lesion tissues and peripheral blood of NL-GLM patients, and the IL-6 inhibitor tocilizumab has demonstrated efficacy in various autoimmune diseases. Based on this, this study intends to conduct a dual-center, single-arm clinical trial to systematically evaluate the efficacy and safety of tocilizumab in the treatment of refractory NL-GLM. The aim is to fill the treatment gap, provide high-level evidence for clinical practice, and ultimately improve patient outcomes.

The purpose of this study is to evaluate the validity and reliability of the Mastitis-score (M-score) and the Breast Inflammatory Symptom Severity Index (BISSI) as measures for assessing symptom severity in non-lactational granulomatous lobular/periductal mastitis (NL-GLM/PDM). This research aims to provide a valid and reliable tool for evaluating both symptom severity and treatment efficacy in NL-GLM/PDM.

Idiopathic granulomatous mastitis (IGM) is a rare, benign inflammatory breast disease that mimics malignancy owing to its features of appearance.In our research, we intended to compare the efficiency of local (intralesional) steroid administration with systemic (peroral) steroid. A total of 36 patients who had been histopathologically diagnosed with IGM and whose other factors had been microbiologically excluded were included in the study. The patients were randomized into two sub-groups that would be treated with systemic and local steroids. Of the patients, 19 were administered with 0.5-1 mg/kg/day peroral systemic steroid, and 17 were administered with 40-200 mg/ml intralesional local steroid regarding the severity of the lesion. All patients were evaluated through physical examination one week after the completion of the treatment. Subsequently, the follow-up of the patients was performed thorough physical examination and ultrasonography and/or magnetic resonance imaging at the 1st, 3rd, and 6th months.

Granulomatous mastitis is a rare, chronic, benign inflammatory disease of the breast that plays a role in many varying etiologies, including infectious and non-infectious causes. Etiological reasons were examined in various studies, but neither etiology nor definite criteria for diagnosis were found. Our aim in this study is to examine the role of cytokines in differentiating the etiology of granulomatous mastitis and using it as a prognostic marker.
