Malignant Neoplasms Of Breast – Definitions & ICD 11 Codes
Definition of Malignant Neoplasms Of Breast: The category refers to primary malignant neoplasms of parenchyma, connective, and soft tissue of the breast, including nipple and areola.

2C61 Invasive carcinoma of breast
2C61.0 Invasive ductal carcinoma of breast
2C61.1 Invasive lobular carcinoma of breast
Definition of Invasive lobular carcinoma of breast: An infiltrating lobular adenocarcinoma. The malignant cells lack cohesion and are arranged individually or in a linear manner (Indian files), or as narrow trabeculae within the stroma. The malignant cells are usually smaller than those of ductal carcinoma, are less pleomorphic, and have fewer mitotic figures.
2C61.2 Invasive pleomorphic lobular carcinoma of breast
Definition of Invasive pleomorphic lobular carcinoma of breast: A grade II invasive lobular carcinoma of the breast, characterised by the presence of neoplastic cells with large and atypical nuclei.
2C61.3 Invasive carcinoma of breast with mixed ductal and lobular features
Definition of Invasive carcinoma of breast with mixed ductal and lobular features: An invasive ductal breast carcinoma associated with a lobular carcinomatous component. The lobular carcinomatous component may be in situ or invasive.
2C61.4 Invasive carcinoma of breast unidentifiable type
Definition of Invasive carcinoma of breast unidentifiable type: A carcinoma that infiltrates the breast parenchyma and where the histopathological type could not be identified.
Inflammatory carcinoma of breast
Definition of Inflammatory carcinoma of breast: An advanced, invasive breast adenocarcinoma characterised by the presence of distinct changes in the overlying skin. These changes include diffuse erythema, edema, peau d’orange (skin of an orange) appearance, tenderness, induration, warmth, enlargement, and in some cases a palpable mass. The skin changes are the consequence of lymphatic obstruction from the underlying invasive breast adenocarcinoma. Microscopically, the dermal lymphatics show prominent infiltration by malignant cells. The invasive breast adenocarcinoma is usually of ductal, NOS type. There is not significant inflammatory cell infiltrate present, despite the name of this carcinoma.

2C62 Inflammatory carcinoma of breast
Malignant phyllodes tumour of breast
Definition of Malignant phyllodes tumour of breast: A phyllodes tumour of the breast characterised by infiltrative margins and a sarcomatous stromal component. The sarcomatous stroma usually displays features of fibrosarcoma. Liposarcomatous, osteosarcomatous, or rhabdomyosarcomatous elements may also be present.
