Perform thorough physical examination, with careful attention to the cheeks, nose, mouth, and eyelids because these are the most common sites of MCC involvement.

Evaluate for a red or violet nodule with telangiectasias and intact skin. In some cases, ulceration may be present.

It is also important to evaluate the mucous membranes of the oral cavity, though these are not common sites for MCCs.
