Encapsulated papillary carcinoma or intracystic papillary carcinoma of the breast is a rare tumour and is a special subtype of carcinoma.

The most relevant histological characteristic is the absence of a myoepithelial cell layer. The lack of such a layer leads to uncertainty in diagnosis and consequent management, depending on whether the tumour is considered an invasive neoplasm or an in-situ neoplasm. This article illustrates the histological characteristics of this subtype of breast cancer, its most common imaging presentation, clinical findings, diagnosis, and treatment.
