Idiopathic granulomatous mastitis: surgery, treatment, and reconstruction.

Idiopathic granulomatous mastitis is a rare inflammatory breast disease that mimics breast diseases such as inflammatory breast carcinoma, infective mastitis, and inflammatory breast disease of known cause. It is a diagnosis made only after excluding other causes, and although the disease is nonmalignant it may be both locally aggressive and recurrent. Definitive treatment may require radical excision and adjunctive treatment with immunosuppressants. Reconstruction following excision of disease has not been previously described. In those patients who undergo reconstruction, both the surgeon and the patient must be aware of complications associated with residual disease, and the potential involvement of donor sites. Treatment should be undertaken as part of a multidisciplinary team including surgeons and physicians with an interest in inflammatory breast disease. We present two patients diagnosed with idiopathic granulomatous mastitis who were referred to our unit for consideration of reconstruction. One patient underwent autologous breast reconstruction and the other contra lateral surgery to achieve symmetry.
