All these lesions represent erythematous scaly plaques and macules that are difficult to diagnose with the naked eye and could be Porokeratosis, actinic keratosis, Bowen’s disease or contact dermatitis, among others. A. Porokeratosis. Clinically we see a non-diagnostic plaque on the forearm and the differential diagnosis in this lesion includes squamous cell carcinoma. B. Porokeratosis. Dermoscopic image of the previous case (A). The ink-test enhances the double keratotic rim. (Non-polarized dermoscopy, original magnification 10X). C. Porokeratosis. Clinically scaly plaque on the lower limb. The differential diagnosis includes Bowen’s disease. D. Porokeratosis. Dermoscopic image of the previous case (C) showing a positive ink-test. (Non-polarized dermoscopy, original magnification 10X). E. Bowen’s disease. Erythematous scaly plaque on a hand. The biopsy confirmed squamous cell carcinoma in situ. F. Bowen’s disease. Dermoscopic images of the previous case (E) showing a negative ink-test (Non-polarized dermoscopy, original magnification 10X).
