Interventions

Group 1: The specific fluorescence signals of the dermatofluoroscopic measurements of 30 seborrhoic keratosis will be analyzed.

Eligibility

Sex/Gender

All

Age

18 Years to 99 Years

Inclusion criteria

Inclusion criteria: Patients with seborrheic keratoses equal to or greater than 18 years of age who had been examined by means of dermatofluoroscopy (15.11.2017-31.12.2017).

Exclusion criteria

Exclusion criteria: Patients with no available dermatofluoroscopic measurements.

Design outcomes

Primary

Measure	Time frame
The primary objective of this retrospective study is to investigate patterns of the melanin-fluorescence spectra in pigmented seborrheic keratoses which were obtained before by means of dermatofluoroscopy.	—

Secondary

Measure	Time frame
Secondary objectives are the evaluation of the usability of dermatofluoroscopy in distinguishing melanoma from benign pigmented seborrheic keratosis and the differentiation between various types of seborrheic keratoses based on specific fluorescence signals and comparison of these results with clinical diagnosis.	—
