RESUMEN
Los tumores de colisión consisten en neoplasias compuestas por dos poblaciones celulares distintas que mantienen una clara diferenciación de sus bordes y que se encuentran adyacentes una de otra en la misma muestra histopatológica. Esta asociación puede corresponder a dos tumores malignos, dos benignos o uno maligno y uno benigno. Son infrecuentes y, en ocasiones, representan un desafío clínico para la detección correcta de ambas neoplasias. Se presenan los casos de tres pacientes con tumores cutáneos de colisión, de estirpe melanocítica combinada con queratinocítica; en dos de ellos ambas neoplasias fueron malignas y en uno, se asociaron una lesión maligna y una benigna.
ABSTRACT
Collision tumors consist of neoplasms composed of two different cell populations that maintain a clear differentiation of their borders, and that are adjacent to each other in the same histopathological sample. This association can correspond to two malignant tumors, two benign, or one malignant and one benign. They are infrequent and, at times, represent a clinical challenge for the correct detection of both neoplasms. Three cases of cutaneous collision tumors of a melanocytic line combined with a keratinocytic line are presented, two of them in which both neoplasms were malignant and one that associated a malignant and a benign lesion.
