Three-point checklist of dermoscopy: an open internet study.

BACKGROUND: In a pilot study, the three-point checklist of dermoscopy has been shown to represent a valid and reproducible tool with high sensitivity for the diagnosis of skin cancer in the hands of a small group of nonexperts. OBJECTIVES: To re-evaluate these preliminary results in a large number of observers independently from their profession and expertise in dermoscopy. METHODS: The study was conducted via the internet to provide worldwide access for participants. After a short web-based tutorial, the participants evaluated dermoscopic images of 165 (116 benign and 49 malignant) skin lesions (15 training and 150 test lesions). For each lesion participants scored the presence of the three-point checklist criteria (asymmetry, atypical network and blue-white structures). Kappa values, odds ratios, sensitivity, specificity and likelihood ratios were estimated. RESULTS: Overall, 150 participants joined the study. The three-point checklist showed good interobserver reproducibility (kappa value: 0.53). Sensitivity for skin cancer (melanoma and basal cell carcinoma) was 91.0% and this value remained basically uninfluenced by the observers' professional profile. Only 20 participants lacking any experience in dermoscopy performed significantly more poorly, but the sensitivity was still remarkably high (86.7%) when considering that they were untrained novices in dermoscopy. The specificity was 71.9% and was significantly influenced by the profession, with dermatologists performing best. CONCLUSIONS: Our study confirms that the three-point checklist is a feasible, simple, accurate and reproducible skin cancer screening tool.

[Darier-Ferrand progressive recurrent dermatofibroma].

Dermatofibroma progressive and recurrent, described by Darier and Ferrand in 1924 is a tumour that grows slowly, and can invade the whole dermis, sectors of the conjunctival interlobular hypodermic tracts, superficial muscular fascia and invade striated muscular fibers, lymphatic ganglia and bones. The most frequent localization is the back and abdomen although it an be seen in other sits of the skin. Ulceration is not frequent. Usually it is most resistant to therapy and recidives frequently. As it is not radio sensible the treatment of first choice is surgery. The evolution is very slow, from months to twenty or more years. We communicate a case of dermatofibroma recurrent of Darier and Ferrand localized in the left supra spinal region, that ulcerated when patient was irradiated with cobalt because she had a lung adenocarcinoma. Possibility radiotherapy produced an alteration in the immunological state of the patient producing by this mechanism the ulceration of the DF.

[Retarded bullous dermographism].

A case of what we denominate Bullous Delayed Dermographism in a woman who had neither allergic nor urticarial antecedents is registered. We comment the features of the lesions which appeared after a period of 4 to 12 hs. This lesions appeared by friction or percussion. We describe the existence of an endocrine and psychological predisposition mechanism and the non specificity of the histopathological characters. The nonexistence of bibliographical antecedents of the illness is noted. Also its difference with bullous and pressure urticaria. This differentiation is based on clinical features, and the nonexistence of allergic antecedents and urticarial lesions. Also on the existence of friction mechanism different to the simple pressure and the nonexistence of immunoglobulins in the subepidermal blister.
