Signet Ring Carcinoma of the Breast : An Uncommon Type of Breast Carcinoma

Signet ring cell carcinoma (SRCC) is a unique subtype of adenocarcinoma characterized by abundant intracellular mucin accumulation. SRCC of the breast, originally grouped as a variant of mucinous carcinoma, was later realized to be a pathologically distinct group [1]. We report a case of SRCC of the breast that is ductal in origin.
