Xanthogranulomatous inflammation is a rare clinico-pathological condition involving many organ systems. Breast involvement with this rare condition reported from a few cases of mastitis has been limited to only microscopic involvement on histology. We would like to report an unusual presentation of this inflammatory process presenting as a solid lump mimicking malignancy in latissimus dorsi donor site scar and implant-based breast reconstruction as a result of a ruptured silicone gel implant. To our knowledge there have been no previous reports on similar presentation published in the literature. This case highlights a rare complication of a leaked silicone gel implant triggering a xanthomatous response in the absence of the usual infective or obstructing etiologies. This condition is of benign nature with complete clearance on surgical excision and excellent clinical prognosis reported from other organ involvement.
