Abstract

2,425 neoplasms from dogs in Bangkok were submitted to the Department of Pathology, Chulalongkorn University, from January 1982 to December 2000 (a 19-year period) and were retrospectively studied to survey the prevalence of the different types of tumours. Histopathological diagnosis was based on the World Health Organization (WHO, 1974) classification of tumours in domestic animals. The prevalence of canine tumours was categorized into skin and soft tissue tumours, 55.05% (1,335 cases); mammary tumours, 28.29% (686 cases); reproductive tumours, 9.69% (235 cases); musculoskeletal tumours, 1.86% (45 cases); digestive tumours, 2.68% (65 cases); hematopoietic and lymphatic tumours, 1.94% (47 cases) and urinary tumours, 0.50% (12 cases). The most common skin and soft tissue tumours were mast cell tumours (22.13%, mean dog age 7.96 yrs), whereas the others were basal cell tumours (9.44%, mean age 7.66 yrs), perianal gland adenomas (8.76%, mean age 11.31 yrs), melanomas (7.10%, mean age 8.96 yrs), squamous cell carcinomas (6.19%, mean age 8.79 yrs), sebaceous gland adenomas (5.27%, mean age 8.59 yrs), canine cutaneous histiocytomas (3.47%, mean age 5.13 yrs), dermatofibromas (3.32%, mean age 7.54 yrs), lipomas (3.17%, mean age 8.60 yrs) and fibrosarcomas (2.79%, mean age 8.35 yrs). The types of 686 mammary tumours were adenocarcinomas (59.91%, mean age 9.14 yrs), benign mixed mammary tumours (23.18%, mean age 9.05 yrs) and adenomas (14.58%, mean age 8.95 yrs). There was no marked differences between sex, breed and the predilection sites of the tumours. The study indicated that canine tumours, especially tumours of skin, soft tissue and mammary gland, are common problems in dogs in Bangkok.
