%X This study describes a rare case of male granulomatous lobular mastitis (GLM) with recurrence in different sites on the ipsilateral side. A 48-year-old male patient presented with no previous history of breast-related disease, and physical examination suggested a mass in the right breast. Ultrasonography revealed a cyst and infection in the right breast. No obvious abnormality was found in laboratory analysis, and a core needle biopsy revealed GLM. Incision and drainage were applied to the right lesion, and symptoms resolved within a few weeks. At 2 years following this initial presentation, the patient reported that the right breast mass reappeared in different locations after the consumption of alcohol. Relevant examination and a core needle biopsy again suggested GLM of the right breast. The patient declined hormone therapy and was subsequently lost to follow-up. After reviewing this case, the course of the disease in this patient, and the connection between gynecomastia and GLM, along with ipsilateral recurrence, are under investigation.
