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.

乳腺包裹性乳頭狀癌或導管內乳頭狀癌為一種罕見的乳腺腫瘤亞型。其最主要的組織學特徵是沒有 肌上皮細胞層,以致令其診斷和及後的治療有不確定性,包括其是否可以認為是侵入性腫瘤或者原 位腫瘤。本文闡述乳腺包裹性乳頭狀癌的組織學特徵、其最常見的影像學表現、臨床表現、診斷以 及治療原則。
