| Sumario: |
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. |
