Papillary lesions in the breasts are uncommon and have a wide range of pathologies. Due to diverse non-specific findings radiologically and histologically, papillary neoplasms are always a challenge to radiologists. Encapsulated papillary carcinomas (EPCs) of the breast, also known as intracystic papillary carcinomas, are a subgroup of intraductal papillary lesions of the breast. We present a case of a painless right breast lump with the aim to describe a rare encapsulated papillary carcinoma and its imaging features.

In recent years, germline mutations in the microRNA (miRNA) processor genes DICER1 and DGCR8 have been coupled to the development of thyroid follicular nodular disease (TFND), thereby casting new light on the etiology of this enigmatic, benign condition in non-iodine-deficient regions. Moreover, DICER1 and DGCR8 mutations have also been reported in rare subsets of follicular cell-derived thyroid carcinomas. Specifically, truncating germline or missense somatic DICER1 mutations have been reported in small subsets of pediatric and adolescent follicular thyroid carcinoma (FTC) and poorly differentiated thyroid carcinoma (PDTC).

We report encapsulated papillary carcinoma and mucinous carcinoma in a case of local advanced bilateral breast cancer. The patient was 78-year-old woman who had bilateral breast tumor. The right palpable tumor was 6 cm in diameter and left tumor was 7 cm in a diameter.

Background: Granulomatous mastitis is a relatively rare benign inflammatory disease of the breast, but it is sometimes difficult to distinguish from breast cancer by imaging. We experienced a case that was definitively diagnosed as granulomatous mastitis from the surgical specimen. The mass appeared as a large cystic lesion on imaging, which is unusual for granulomatous mastitis, and was initially suspected to be an encapsulated papillary carcinoma.

Encapsulated papillary carcinoma (EPC) represents a distinct entity within the spectrum of breast papillary tumors, typically manifesting as a retroareolar mass. This rare subtype can be effectively visualized using ultrasound and magnetic resonance imaging, which reveal characteristic cystic-solid nodules. Histopathologically, EPC is defined by a papillary tumor structure with a well-defined fibrous capsule, devoid of myoepithelial cells both within and around the capsule.
