The name comes from finger-like projections, or papuleswhich are seen when the cells are looked at under the microscope. Many papillary tumors are benign. These are called papillomas.
Papillary carcinoma of the breast, also known as intraductal papillary carcinoma, is a rare type of breast cancer accounting for only 0. Invasive cancers begin growing into the milk ducts of the breast and move to invade fibrous or fatty issue outside the duct. Papillary carcinomas are most often diagnosed in women who have already gone thorough menopause.
Papillary breast cancer is a very uncommon from of infiltrating ductal breast cancer. So, the characteristics of this cancer are a well-defined margin with many small projections. We have a newer page, with up-to-date references on types of breast cancer, including papillary breast cancer, Here.
Papillary carcinoma of the breast is a rare ductal breast malignancy. Papillary carcinomas may be solitary or multiple. When the epithelium of a papillary carcinoma has features diagnostic of intraductal carcinoma, the lesion is classified as papillary ductal carcinoma in situ. If a cystic component is present, the tumor is described as an intracystic papillary carcinoma ICPC.

We report an unusual case in a year-old perimenopausal female who came with a complaint of lump in right breast for duration of 1 year. A simple mastectomy was undertaken for histopathological study and immunohistochemistry IHC which showed characteristic features of an invasive papillary breast carcinoma. We present this case in view of its rarity and to highlight this clinicopathological subtype for its good prognosis and to avoid overtreatment.
Forward to 5D on rare types. Back to 5B on lobular types. This is because an adequate histological assessment requires adequate sampling of the entire lesion for microscopic review. In the The World Health Organization WHO guidelines, invasive papillary carcinoma is now regarded as an adenocarcinoma of the breast with a micro-papillary morphology, and there is no prognostic meaning.
