three synchronous bilateral solid papillary carcinomas of the breast with different radiologic findings: a case report

Papillary carcinoma of the breast is a rare malignant tumor that is known to account for only approximately 1% - 2% of breast carcinomas in women. among papillary carcinomas, solid papillary carcinoma (spc) is a rare breast carcinoma that occurs primarily in elderly women. it is known that approximately 95% of the cases occur in a unilateral breast. the imaging findings for spcs are not well established, and most of the published articles are about pathological findings. moreover, there have been no reports of spcs occurring in both breasts at the same time. we report here a case of three synchronous bilateral breast spcs in patient with palpable mass, each showing different radiologic findings. although imaging findings that distinguish between malignant and benign papillary lesions are unclear, familiarity with the features of spcs may be helpful in establishing imaging findings for these lesions
