Esophageal tumors: what are two most common types? What is most common in USA and which is most common in the world? What do most look like on gross exam (regardless of histology)

*Squamous Cell Carcinoma (SCC)* – malignant proliferation of squamous cells; *most common worldwide* – way to remember is that the rest of the world smokes more than USA *Adenocarcinoma* – malignant proliferation of glands; *most common in USA* *Regardless of histology, 60% of tumors are polypoid or exophytic on gross examination*.

What is Histology?

Histology is the study of the microscopic structure of tissues and organs. It focuses on their form and function, as well as their cellular components. Histology is vital for understanding how biological systems work, as well as in diagnosing diseases.The field of histology dates back to the 1800s, when two German scientistsJohannes MÃ¼ller and Georg Meissnerbegan studying the microscopic anatomy of animals. They looked at tissue samples under microscopes and described their cellular structure in detail. This led to a greater understanding of physiology and pathology, which laid the foundation for modern medicine. Today, histologists use advanced technologies such as computer-aided imaging (CAI) and electron microscopy to look at tissue samples in even greater detail than before. In CAI, digital images are created using specialized software that can magnify tissue samples up to 1000 times their original size. Electron microscopy also uses powerful lenses to magnify tissue samplesin this case up to one million times. These tools allow researchers to identify different structures within cells that were previously impossible or difficult to observe without special equipment (such as organelles). Histologists use these tools in medical laboratories around the world for diagnosis and research purposes. For instance, they may take biopsies from patients with suspected diseases or examine human tissues after death for forensic studies. Histological tests can also be used in research studies involving cell biology, genetics, immunology, endocrinology, neurology, pharmacology and more. Overall, histology is an essential field of study that has greatly contributed to our understanding of human biology over time. It has enabled us to better diagnose diseases and understand how various body systems work together on a microscopic level providing invaluable insights into health science today.
