El melanoma constituye la forma más común de cáncer mortal de piel y su incidencia está aumentando más rápido que cualquier otro tipo de cáncer prevenible. Las tasas de supervivencia a cinco años dependen de la etapa de la enfermedad en el momento del diagnóstico. La sobrevida disminuye a medida...
Pigmented Bowen's disease is rare, though more prevalent in men. It presents as a well-delineated plaque in areas unexposed to sun. There are reports of association with seborrheic keratosis, solar lentigo or exuberant pigmentation of genital and intertriginous regions. A specific dermoscopy finding is t...
