Résumé
Non-puerperal mastitis(NPM)is a group of chronic inflammatory diseases with breast pain,lumps,abscesses and sinus tracts/fistulas as the main clinical manifestations,which is easily confused with breast cancer or other benign breast diseases.NPM always leads to a long treatment cycle and high recurrence rate,which may cause a large economic and psychological burden to patients.At present,the etiology and pathogenesis of NPM are still unclear,but it has a certain correlation with immune abnormality,bacterial infection,hormone disorder and other factors.Although several diagnostic methods available,the diagnosis of NPM relies on histopathological examination mainly.The treatment methods of the disease include observation and follow-up,pharmacotherapy,surgical treatment,etc.,but there is still no unified standard for specific treatment timing and treatment selection.In view of the controversy over etiology and treatment selection of NPM,this paper comprehensively summarizes the latest research progress in disease characteristics,clinical diagnosis and treatment of NPM based on domestic and foreign literature,aiming to provide reference and inspiration for the selection of reasonable clinical diagnosis and treatment.
