Breast malignancies diagnosed from screening mammography most commonly present as a new or enlarging lesion at the time of diagnosis. We present the unusual case of an encapsulated papillary carcinoma that demonstrated decreasing size on mammogram over several subsequent years. We review the unique imaging and histologic findings of papillary carcinoma that make this imaging conundrum possible.
