Accuracy of dermoscopic criteria for discriminating superficial from other subtypes of basal cell carcinoma.

Background: The management of basal cell carcinoma (BCC) depends, among other factors, on its histopathologic subtype. Although dermoscopic criteria of BCC have been investigated, the possible role of dermoscopy in predicting the tumor subtype remains unclear.

Objectives: We sought to assess the diagnostic accuracy of dermoscopic criteria for differentiating superficial BCC (sBCC) from other BCC subtypes.

Photoletter to the editor: Dermoscopy in clinically atypical psoriasis.

Diagnosis of psoriasis is usually established clinically, based on the characteristic morphology and distribution of lesions. However, cases of psoriasis with atypical presentation do exist. In this manuscript we report and highlight the significant role of dermoscopy in the diagnosis of three clinically atypical and heterogeneous cases of psoriasis.
