Society Studies

The following studies have been activated. If you like to participate to a specific study please send an email to the coordinator of the study. General criteria for authorship and study proposals are available here.

The rules for publishing data from dermoscopy photographs have changed (as of Feb 2009). To publish retrospective studies using images from patients you need the following requisites:

1. You have obtained verbal or written consent (depending upon the rules of your IRB/Ethics review board) for the use of the images that “were taken during routine patient care”.


1. You have an Institutional Review Board or Ethics Committee that has allowed the use of these images in studies


2. You have an IRB waiver for the use of the images


3. Your country does not require IRB review for such a collection of images.

If you are in the last category we will need to name the countries in the Methods section. All participants are encouraged to contact their IRB to confirm what they should be doing.

Active Studies

  1. Dermoscopy of primary cutaneous lymphomas: To investigate dermoscopic features of PCLs versus those of other skin conditions that commonly enter into the differential diagnosis in order to find possible features which may be of aid in the recognition of PCLs and assess their accuracy (sensitivity and specificity). Coordinators: Enzo Errichetti enzoerri(a),  Zoe Apalla,  Giuseppe Stinco,  Aimilios Lallas.
  2. Human Against Machine (HAM10000):  To compare the accuracy of the diagnosis of dermatoscopic images of pigmented lesions by expert human observers (dermatologists and skin cancer specialists) with the accuracy of a convoluted artificial neural network.  Contact: Harald Kittler, harald.kittler(a)
  3. Dermoscopic Patternd of Cutaneous Metastases. Coordinators: Danica Tiodorovic danica.dr(a) and Harald Kittler  harald.kittler(a)

  5. Clinical and Dermoscopic Features of Thin Nodular Melanoma
    Coordinator: Dr. Alexander J. Stratigos and colleagues. Please refer to alstrat2(a) for further details and forms.
  6. Experience in Dermoscopy/Dermatoscopy (Damiani Giovanni, Ribero Simone, Puig Susana) : This study wants to perform a new algorithm to quantify dermoscopists’/dermatoscopists’ experience in all pigmented and non pigmented lesions, in order to set a measuring tool of experience and feasibility of dermatologists operating in dermatoscopy/dermoscopy.

  12. World Wide Dermoscopy Map, After the first two collections of funny images on dermoscopy – we like to start a new project for the IDS meeting in Buenos Aires (2021) and for the IDS home page. Therefor we ask you for country images on dermoscopy on which you see any country, continent, city, map etc. Contact: Andreas Blum (

  9. IDS collaborative study on BAP1-deficient nevi: clinical and dermoscopic features
    The primary objective of this study is thus to correlate the clinical and dermoscopic morphologies associated with BDN. In doing so, we can improve the diagnosis of these lesions, as well as aid in the identification of individuals at increased risk for the development of systemic and cutaneous malignancies.
