[A case of secretory carcinoma of the breast in an adult].

This report describes a case of secretory carcinoma of the breast in the adult. The patient, a 56-year-old female, had a tumor, 1 cm in size, in the upper outer quadrant of her left breast, and Patey's modified radical mastectomy was performed. No nodal metastases were found. Although secretory carcinoma of the breast has been called "juvenile carcinoma", 27 adult cases have been reported previously in the English and Japanese literature. It is reported to have a good prognosis but surgical therapy with an axillary node dissection is recommended, since axillary metastases have been found in approximately 30% of the recorded cases.
