Poorly differentiated adenocarcinoma is a type of cancer that begins in glandular cells (cells that produce mucus or other fluids), which are found in many organs, including the stomach, intestines, lungs, and pancreas. In this type of cancer, the cancer cells have lost many of their normal structures, making them look very different from the …

Adenocarcinoma of the Small Intestine: Understanding Your Pathology Report

Adenocarcinoma is the most common type of cancer that starts in the small intestine, the long, narrow part of the digestive system that absorbs nutrients from food. This type of cancer begins in the gland-forming cells that line the inside surface of the intestine. These cells normally help with digestion and nutrient absorption, but in …

PMS2: Definition

PMS2 is a gene that produces a protein involved in repairing mistakes in a cell’s DNA. It is one of four key mismatch repair (MMR) proteins — along with MLH1, MSH2, and MSH6 — that work together to find and fix small errors that occur when DNA is copied during cell division. PMS2 and MLH1 …

What is MITF?

MITF (microphthalmia-associated transcription factor) is a protein that helps regulate the development, function, and survival of certain types of cells, particularly melanocytes. Melanocytes are specialized cells found in the skin and other tissues where they produce a pigment called melanin. This pigment gives color to the skin, hair, and eyes. MITF plays a crucial role …

What is a translocation?

A translocation is a type of genetic change where a piece of one chromosome breaks off and attaches to a different chromosome. Chromosomes are structures inside your cells that carry DNA, the instructions your body uses to grow, repair itself, and function properly. When pieces of chromosomes switch places, they can create new combinations of …
