Introduction And Importance:
Idiopathic granulomatous mastitis (IGM) is an uncommon, benign, chronic inflammatory breast disease of unknown etiology, unpredictable duration, and unclear therapy.
Presentation Of Case:
A 41-year-old woman presented with pathological nipple discharge for which ductoscopy was performed. Post-ductoscopy, the patient developed abscesses in her breast with histopathological confirmation of granulomatous mastitis (GM).
Clinical Discussion And Conclusion:
IGM has an unknown etiology and atypical presentation. This is the only case described in which IGM occurred after ductoscopy. This can be related to trauma-induced GM or underlying IGM aggravated by ductoscopy.
