Squamous carcinoma or squamous cell carcinoma. Squamous carcinoma or squamous cell carcinoma is a type of non-small cell lung cancer (NSCLC) where the cells look like the flat cells (called squamous cells) that line the airways. It is a common type of lung cancer in the United States.
The first patient had a biopsy diagnosis of triple negative invasive carcinoma of no special type of the breast. Sample mix-up with another biopsy was suspected, because in her post-chemotherapy mastectomy specimen, a hormone receptor-positive lobular carcinoma was diagnosed.

Microscopic (histologic) description. Giant cells are associated with vascular stroma with extravasated red blood cells and hemosiderin, also chronic inflammatory cells and fibroblasts. Giant cells have variable size and variable numbers of nuclei. Similar histologic features in nodal metastases and recurrences ( Arch Pathol Lab Med 1986;110:636 )
Terminology. The 4 th edition (2012) of the WHO classification of tumours of the breast changed the preferred terminology from "invasive ductal carcinoma (IDC), not otherwise specified (NOS)" to "invasive breast carcinoma (IBC) of no special type (NST)" 4. The rationale is that the term "ductal" relies on unproven histogenetic assumptions for
A study of EPCs using invasion-associated markers, including several matrix metalloproteinases, E-cadherin, and TGF-β1 showed that levels of some of these markers were similar to those seen in invasive carcinoma of no special type (NST), whereas others showed levels similar to those seen in DCIS.
Background Triple Negative breast cancer (TNBC) includes a heterogeneous group of tumors with different clinico-pathological features, molecular alterations and treatment responsivity. Our aim was to evaluate the clinico-pathological heterogeneity and prognostic significance of TNBC histologic variants, comparing “special types” to high-grade invasive breast carcinomas of no special type Invasive ductal carcinoma of no special type - medullary pattern With the 5th Edition of the WHO Classification, medullary carcinoma ceased to be considered a distinct subtype of breast cancer Invasive carcinoma of no special type, with central acellular zone/fibrotic focus, is one of the triple negative carcinomas with basal-like features. When a myxoedematous infarcted stroma and/or fibrotic focus with a high-grade cancer cells is seen in the biopsy or excision specimens, this diagnosis should be considered, as this may lead to

The duration of disease-free survival (DFS) was 226.5 months for the No-Special Type BC group, 216.7 months for the No-Lobular Special Type BC group, and 197.2 months for the Invasive Lobular Special Type BC group, whereas the duration of overall survival (OS) was 233.2 months for the No-Special Type BC group, 227.9 for the No-Lobular Special
