Papillary carcinoma of the breast is a rare type of breast malignancy, less than 2% of breast cancers, and only a part of them are encapsulated papillary carcinoma (EPC). Usually, EPC are low-grade luminal like tumours. The authors report a case of a 50-year-old female with the diagnosis of an unusual high-grade triple negative EPC with an area of invasive papillary carcinoma and negative axillary lymph nodes. Considering its rarity, the description of this case and clinical management are important to better understand this entity and choose the best clinical practice.
