This retrospective survey was undertaken between 2002 and 2007 on samples from dogs residing in Grenada. The objectives of the study were to identify the most common histologic types of canine cutaneous tumors, determine the relative frequency of each tumor type, and compare results to reports from other regions. In a series of 225 skin masses examined, the proportion of neoplasms was 72% whereas nonneoplastic tumors accounted for 15.6%, and inflammatory conditions constituted 12.4%. There were 10 types of nonneoplastic tumors with hamartomas being the most common (28.5%), followed by sebaceous hyperplasia (25.7%) and fibroepithelial polyps (22.8%). The 10 most common cutaneous neoplasms were hemangiosarcomas (19.1%), histiocytomas (8.6%), melanocytomas (8%), mast cell tumors (6.8%), lipomas (6.8%), hemangiopericytomas (6.2%), papillomas (5.6%), fibrosarcomas (5.6%), hemangiomas (4.9%), and squamous cell carcinomas (4.3%). Tumors of vascular origin and transmissible venereal tumors were more common in dogs in our study than reported from other regions.
这项回顾性调查于2002年至2007年间对格林纳达犬的样本进行。该研究的目的是确定犬皮肤肿瘤最常见的组织学类型，确定每种肿瘤类型的相对频率，并将结果与其他地区的报告进行比较。在一系列225个检查的皮肤肿物中，肿瘤的比例为72%，而非肿瘤性肿瘤占15.6%，炎症性病变占12.4%。有10种非肿瘤性肿瘤，其中错构瘤最常见（28.5%），其次是皮脂腺增生（25.7%）和纤维上皮息肉（22.8%）。10种最常见的皮肤肿瘤为血管肉瘤（19.1%）、组织细胞瘤（8.6%）、黑素细胞瘤（8%）、肥大细胞瘤（6.8%）、脂肪瘤（6.8%）、血管外皮细胞瘤（6.2%）、乳头状瘤（5.6%）、纤维肉瘤（5.6%）、血管瘤（4.9%）和鳞状细胞癌（4.3%）。在我们的研究中，血管源性肿瘤和传染性性病肿瘤在犬中比其他地区报告的更为常见。
