Cribriform morular thyroid carcinoma (CMTC) is a rare type of thyroid gland cancer. The thyroid is a butterfly-shaped gland in the neck that produces hormones important for metabolism. Cribriform morular thyroid carcinoma is unique due to its specific appearance under the microscope and its association with certain genetic conditions. What are the symptoms of cribriform …

Non-keratinizing squamous cell carcinoma of the lung is a type of non-small cell lung cancer (NSCLC). The term “non-keratinizing” means that this particular type of cancer does not show the typical keratin pearl formation or extensive keratinization that is often observed in the more common keratinizing squamous cell carcinoma. Non-keratinizing squamous cell carcinoma typically arises in …

In pathology, the term nonkeratinizing describes squamous cells that have not undergone keratinization, a process where cells produce and store large amounts of a protein called keratin. Keratin is a structural protein that makes cells tough and resistant to external physical forces. Nonkeratinizing squamous cells are normally found in mucosal tissues throughout the body where …

Basal cells are found in the basal or deepest part of the epithelium, a thin layer of tissue that lines the surface of most organs. These cells have a crucial role in maintaining the integrity and function of the epithelium. Specifically, they serve a pool of less differentiated cells that replace the mature or differentiated …

Dyskeratotic cells are squamous cells that have undergone premature or abnormal keratinization, a process by which cells produce and accumulate a protein called keratin. Under microscopic examination, these cells are smaller and pinker than normal squamous cells. Dyskeratotic cells can be seen in a variety of precancerous, cancerous, infectious, and inflammatory conditions. What conditions are …

Fibroblasts are a type of cell normally found in connective tissue. They play an important role in maintaining the structural framework of tissues and organs in the body. They are one the most common types of cells found in connective tissue and are primarily involved in producing and secreting the extracellular matrix, which provides structural …

Apocrine metaplasia describes a change where the cells normally found in a tissue are replaced by cells that resemble the apocrine cells found in the skin. It constitutes a benign (non-cancerous) change. In pathology, metaplasia is the replacement of one type of differentiated cell with another. Apocrine cells, characterized by their large size, round shape, …

Glandular cells are specialized epithelial cells that form the functional units of most internal organs. They are involved in the production and secretion of substances that aid in the normal activity of the organ. These substances may include enzymes, hormones, mucus, or other products that are released into ducts, surfaces, or the bloodstream for various …

Metastatic adenocarcinoma refers to cancer that has spread from its original (primary) site to other parts of the body. The term adenocarcinoma specifically refers to a type of cancer made up of glandular cells, which are the cells found inside most internal organs. For example, if someone has metastatic adenocarcinoma of the breast, it means …
