[Who examines the oral mucosa during the total body skin examination?].

Using the example of a 72-year-old male patient, the following questions are posed to the reader: Who asks his patients: "Open your mouth please", "Please elevate your tongue", or who uses, if possible, his dermatoscope to examine a suspicious and reachable lesion of the mucosa? In this patient a bruise-like red tumor was found in the sublingual area but had completely disappeared by the follow-up after 6 weeks. To protect the dermatoscope when it is used on the mucosa, it can be covered with plastic food wrap.
