How to diagnose Merkel Cell Carcinoma ?
Tests and procedures that examine the skin are used to detect (find) and diagnose Merkel cell carcinoma. The following tests and procedures may be used:         -   Physical exam and history : An exam of the body to check general signs of health, including checking for signs of disease, such as lumps or anything else that seems unusual. A history of the patients health habits and past illnesses and treatments will also be taken.    -  Full-body skin exam: A doctor or nurse checks the skin for bumps or spots that look abnormal in color, size, shape, or texture. The size, shape, and texture of the lymph nodes will also be checked.    -  Skin biopsy : The removal of skin cells or tissues so they can be viewed under a microscope by a pathologist to check for signs of cancer.
