Optional medical device diagnostics – depending on the results of the history, physical examination, laboratory diagnostics, and obligatory medical device diagnostics – for differential diagnostic clarification.
- Dermatoscopy (reflected light microscopy; increases diagnostic accuracy).
- Sonography (ultrasound examination), depending on the localization to determine the depth/spread.
- Confocal laser scanning microscopy (KLSM; engl. Confocal laser scanning microscopy (CLSM); non-invasive method for high-resolution diagnosis of tissue by means of reflected light technique (= ex vivo); this allows high-resolution imaging of near-surface changes with microscopic resolution of 1-3 µm in horizontal sectioning; thus a possible alternative to conventional histology/fine tissue examination) – for differential diagnosis of melanocytic lesions, ie. i.e. between malignant melanoma, dysplastic nevi and other pigmented lesions.
