Cytodiagnosis of secretory carcinoma of the breast

Secretory carcinoma is a rare form of breast carcinoma which has a predilection for juveniles and young adults (usually less than 30 years of age), becoming progressively less common with advancing age. It is a low grade breast carcinoma which shows distinct features at histology. Diagnosis of this carcinoma on fine needle aspiration cytology (FNAC) is difficult. We report a case of a 62-year-old woman diagnosed to have secretory carcinoma of breast on FNAC. Histopathological examination confirmed the diagnosis. The recognition of secretory carcinoma is important because the cytological findings can be confused with those of lactating breast. Preoperative diagnosis is essential for appropriate surgical therapy. Secretory carcinoma is reported to have 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.
