La dermatoscopia es una herramienta diagnóstica no invasiva, que en manos de médicos bien capacitados en esta técnica aumenta la certeza diagnóstica en 5 a 30%. Actualmente existen criterios bien establecidos para diagnosticar las queratosis seborreicas por dermatoscopia, como los quistes de milium, los tapones folicu-lares, las fisuras, las crestas y estructuras en huella digital, así como criterios adicionales (vasos en horquilla, borde apolillado, estructuras tipo red pigmentaria, etc.). Es importante conocer estos criterios, ya que por el polimorfismo de las lesiones (a pesar de ser consideradas lesiones "banales") éstas pueden confundirse clínicamente o coexistir con tumores malignos, como el carcinoma basocelular y el melanoma.

We present three cases of epidermal tumors different from clear cell acanthoma that have the same "string of pearls" vascular pattern. Even though most authors keep considering the "string of pearls" vascular pattern an almost pathognomonic sign of clear-cell acanthoma, the cases presented here suggest that some other epidermal tumors can also show this pattern.

EP commonly occurs on the soles and lateral aspects of the feet, but it can also be found on other anatomic sites. It appears more frequently in adults. The most common clinical presentation is a firm nodule, from pink to red in color, sometimes slightly pedunculated, measuring up to 2 cm in diameter. Sometimes EP presents as a small papule or as a verrucous plaque. Occa
