Diagnostic and Treatment Algorithm for Morbihan Disease (MD) This flow chart illustrates the comprehensive approach to diagnosing, managing, and evaluating MD in our study. The process begins with the initial patient presentation and progresses through diagnostic steps, including clinical evaluation, laboratory tests, and histopathological analysis. Once MD is confirmed, the treatment modalities, including oral medications (tetracycline, corticosteroid, isotretinoin), topical treatments (ivermectin, tacrolimus), and intralesional steroid injections were applied in a single or combination manner. The treatment evaluation phase involves an initial response assessment at 1 month, followed by regular follow-ups every 6 months. Treatment outcomes are categorized as either complete response with no recurrence or poor response, which includes partial response, recurrence, or no response
