COINCIDENT GRANULAR-CELL TUMOR OF THE BREAST WITH INVASIVE DUCTAL CARCINOMA

Granular cell tumours of the breast are rare lesions which are almost always benign. They are of interest because their clinical, radiologic al and pathological appearances often closely resemble those of malign ancy. A case is described in which screening mammography in an asympto matic 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 tumour s is very rarely described and an association with breast carcinoma is unknown.
