title: Case report: coincident granular cell tumour of the breast with invasive ductal carcinoma.
abstract: Granular cell tumours of the breast are rare lesions which are almost always benign. They are of interest because their clinical, radiological and pathological appearances often closely resemble those of malignancy. A case is described in which screening mammography in an asymptomatic woman led to the diagnosis of simultaneous invasive intraductal carcinoma in one breast and benign granular cell tumour in the other. Granular cell tumour of the breast coincident with other breast tumours is very rarely described and an association with breast carcinoma is unknown.
