🌥️ Invasive Carcinoma Of No Special Type

Breast tumors with neuroendocrine (NE) differentiation comprise an uncommon and heterogeneous group of tumors, including invasive breast cancer of no special type (IBC-NST) with NE features, neuroendocrine tumors (NETs), and neuroendocrine carcinoma (NEC). The most recent World Health Organization (WHO) classification in 2019 defined neuroendocrine neoplasms (NENs) of the breast (Br-NENs) as

Several patients have a history of contralateral or ipsilateral invasive carcinoma of no special type with a tumor size ranging from 0.6 to 18.0 cm (mean: 2.3–3.7 cm), and approximately 40% of NECB has axillary lymph nodal metastasis at diagnosis (15, 16, 18, 19).

Forward to section 5B on lobular types Back to 4D Men generally present with breast cancer at an older age compared with women. Histologically, MBC is often of grade 2, hormone receptor positive, HER2 negative, and no special type carcinoma although in situ and invasive papillary carcinomas are common. Reporting and staging are similar to female breast cancer. The 2 main types of in-situ carcinoma of the breast are: Ductal carcinoma in situ (DCIS), also known as intraductal carcinoma. Lobular carcinoma in situ (LCIS) Sometimes DCIS and LCIS are both found in the same biopsy. In-situ carcinoma with duct and lobular features means that the in-situ carcinoma looks like DCIS in some ways and LCIS in some ^{Invasive carcinoma of no special type also known as invasive ductal carcinoma or ductal NOS and previously known as invasive ductal carcinoma, not otherwise specified is a group of breast cancers that do not have the “specific differentiating features”. Those that have these features belong to other types.} sn7xwom. 359 216 46 373 300 5 171 87 70
