Adenosquamous carcinoma is a type of cancer made up of abnormal glands and squamous cells. It shares features with two other types of cancers – adenocarcinoma and squamous cell carcinoma. Adenosquamous carcinoma can start anywhere in the body where glands and squamous cells are normally found. However, it is more commonly seen in the pancreas, lung, skin, cervix, and bladder. Adenosquamous carcinoma is a rare and aggressive type of cancer that can spread to lymph nodes or other parts of the body. This diagnosis can only be made after a sample of the tumour is examined under the microscope by a pathologist.
