Abstract

Our aim was to describe clinicopathologic features of secretory carcinoma on a cohort of cases. We retrieved reported cases of secretory carcinoma of breast (SCB) in the Section of Histopathology, Department of Pathology & Microbiology, Aga Khan University Hospital Karachi, from May 2004 to December 2011. The slides were reviewed, and clinicopathologic features were noted. A total of 8 cases of SCB were found. The age ranged from 17 to 60 years (median, 41 years) with a female to male ratio of 7:1. Lumpectomy was done in 6 cases, and mastectomy, in 2 cases. The tumor size ranged from 2.5 to 10 cm (mean, 5.5 cm). Histologically, abundant extra- and intracellular secretory material was seen in all cases. Most of the tumors showed mixtures of patterns with dominant microcystic and papillary patterns. In situ component was seen in only 1 case. Lymph node metastases were seen in both cases with lymph node sampling. In conclusion, SCB is a rare type of ductal breast carcinoma. The papillary pattern of SCB is rare according to published data but was seen in most of our cases. In situ secretory carcinoma is even rarer, and to date, we have seen a single case only. Although most occur in women, these can be seen in men as well.
