A case of mucocele like tumor diagnosed by mammotome

Abstract

A 48-year-old woman was pointed out to have calcifications of the right breast on a screening mammography and had a check up in our Hospital. We observed that the small round calcifications were clustered and classified Category 3. Vacuum-assisted biopsy (Mammotome) specimen of approximately 3 mm in diameter demonstrated dilatation of the mammary ducts and pool of mucin, including small gritty calcifications and was diagnosed that she had a mucocele like tumor (MLT). So we performed a wide excision including the calcifications. The excised specimen showed no malignancy, and the final diagnosis was benign MLT. We present a case of MLT which was diagnosed by a Mammotome before the operation. This is a rare case and so far there is no domestic report like this.
