Plasmocitoma extramedular de nódulos linfáticos en un perro

RESUMEN

El plasmocitoma extramedular es una masa tumoral constituida por células plasmáticas distantes de la médula ósea, clasificándose como tumor cutáneo y no es de presentación frecuente en perros. Se atendió en la en el centro veterinario ZOOGAR un paciente canino macho, mestizo, de ocho años de edad con evidente linfadenopatía generalizada al examen clínico. Al examen histológico post mortem, reveló células plasmáticas en nódulos linfáticos, encontrándose focos de necrosis, coagulación y hemorragia tanto en la parte cortical como la medular; con remodelación tisular por tejido conectivo. El hígado y bazo presentaron evidencia de metástasis, específicamente el hígado, a nivel de las triadas portales y áreas centrolobulillares. Los plasmocitomas extramedulares de nódulos linfáticos son raros en perros y no ha sido reportado en estos órganos
