Canine cutaneous tumors in Sriracha district, Chonburi province, Thailand

Abstract

A retrospective epidemiological study was conducted to identify a relative frequency of canine cutaneous tumors during January 2018 - December 2019 across Sriracha district, Chonburi province, Thailand and demonstrated the associations between age, sex, neuter status, breed types, anatomical locations, and weight with skin tumors diagnosis. A total of 94 canine biopsy specimens according to 87 dogs were submitted for histopathological classification. The highest relative frequencies in this study were mast cell tumors (19.1%), followed by melanoma (8.5%), lipoma (7.4%), and histiocytoma (6.4%). The most frequent locations of tumor were found on limbs (24.4%), head (23.5%), trunk and flank (18.3%), and perineum (13.9%). A single type of cutaneous tumor was more regularly found on dogs than multiple types of tumor. The risk of developing cutaneous tumors increased significantly in the large-breed dogs (greater than 20 kg in weight) compared to medium- and small-breed dogs. Male dogs had 5.28 times of the odds having tumors compared to female dogs with 0.002 of P-value. Moreover, the occurrence of skin tumors is more common in elderly dogs. Our findings serve as a useful baseline information for regional veterinarians to establish a preliminary diagnosis of canine cutaneous tumors.
