The treatment of GM is controversial, and currently, there is no consensus about the most appropriate therapy. Case Presentation: We presented a unique, atypical GM case with a prolonged disease course that ultimately led to a bilateral mastectomy. A conservative therapeutic approach and limited or wide surgical excisions have failed to prevent unfavorable outcomes in both the initial presentation and recurrent disease. Conclusions: There’re no clear data in the literature delineating persistent recurrences of GM after conservative treatment and multiple surgeries. Obtaining a disease-free surgical margin might be an important prognostic factor for a lasting relapse-free clinical resolution.展开更多
