HERENIO, Alzinira Sousa et al. Porokeratosis simulating Bowen’s disease on dermoscopy. An. Bras. Dermatol. [online]. 2016, vol.91, n.5, suppl.1, pp.119-121. ISSN 0365-0596.

Porokeratosis is a disorder of epidermal keratinization characterized by the presence of annular hyperkeratotic plaques. Its etiopathogenesis is not yet fully understood, but a relationship with immunosuppression has been reported. Dermoscopic examination revealed a classic yellowish-white ring-like structure that resembled “volcanic crater contour” – the so-called cornoid lamella. We describe a case of porokeratosis in a female patient with chronic lymphedema, which was similar to Bowen’s disease due to the many glomerular vessels seen on clinical examination and dermoscopy.

Keywords : Dermoscopy; Bowen’s disease; Lymphedema; Porokeratosis.
