Canine perineal tumours

One hundred and thirty nine canine perineal tumours were histologically evaluated. The vast majority (134 tumours = 96.4 Yo) appeared to originate from the characteristic glandular structures of this region. They were classified as well differentiated perianal gland tumours (58.3 Yo). as moderat...

PERRO DOG CANCER ONCOLOGÍA ONCOLOGY PATOLOGÍA ANIMAL ANIMAL PATHOLOGY One hundred and thirty nine canine perineal tumours were histologically evaluated. The vast majority (134 tumours = 96.4 Yo) appeared to originate from the characteristic glandular structures of this region. They were classified as well differentiated perianal gland tumours (58.3 Yo). as moderately or poorly differentiated perianal gland tumours (21.6 %) and as carcinomas without perianal gland differentiation (16.5 Yo). Only 5 tumours (3.6 Yo) appeared to originate from non-characteristic perineal structures. A prominent male predominance was found with respect to the perianal gland tumours, whereas the carcinomas showed a distinct female predisposition. Tumours showing perianal gland differentiation almost invariably will have a benign behaviour. The carcinomas lacking any perianal gland differentiation often show a distinct malignant behaviour with metastases to regional lymph nodes and internal organs. These malignant neoplasms showed morphological and clinical features comparable to canine anal sac gland adenocarcinomas and carcinoids in man and animals. Se evaluaron histológicamente ciento treinta y nueve tumores perineales caninos. La gran mayoría (134 tumores = 96,4 Yo) parecían originarse en las estructuras glandulares características de esta región. Se clasificaron como tumores de glándulas perianales bien diferenciados (58,3 Yo). como tumores de glándulas perianales moderadamente o mal diferenciados (21,6%) y como carcinomas sin diferenciación de glándulas perianales (16,5 Yo). Sólo 5 tumores (3,6 Yo) parecían originarse en estructuras perineales no características. Se encontró un predominio masculino prominente con respecto a los tumores de glándulas perianales, mientras que los carcinomas mostraron una clara predisposición femenina. Los tumores que muestran una diferenciación de las glándulas perianales tienen casi siempre un comportamiento benigno. Los carcinomas que carecen de diferenciación de las glándulas perianales suelen mostrar un comportamiento claramente maligno con metástasis a los ganglios linfáticos regionales y a los órganos internos. Estas neoplasias malignas presentan características morfológicas y clínicas comparables a los adenocarcinomas de las glándulas del saco anal canino y a los carcinoides en el hombre y en los animales.
