Psoriasis vs. its mimickers: when the dermatoscope casts light on challenging cases in everyday clinical practice.

Overall, 1221 patients with clinical differential diagnosis of necessarily psoriasis and >=1 of morphologically similar inflammatory and/or cancerous erythematosquamous conditions lacking a definitive clinical diagnosis were included. On the other hand, dermoscopic findings are only relevant within the overall clinical framework of the patient.4,5 Accordingly, our study stresses the importance of integrating dermoscopy in the clinical examination when rendering a diagnosis, particularly when assessing challenging lesions mimicking diverse skin conditions, either malignant or inflammatory. Accurate dermoscopic criteria of various skin diseases exist, but the extent to which they improve diagnosis over the unaided-eye examination in the real clinical setting remains unclear.
