Squamous cell carcinomas (SCC) are uncommon in reptiles and there have been few reports of neoplasia in Australian crocodiles, despite increased numbers being raised in captivity.
We report a locally invasive SCC in the hindlimb of a wild-caught saltwater crocodile (Crocodylus porosus) with hepatic metastasis. The gross appearance was soft tissue swelling adjacent to the nail bed, progressing to abscessation incorporating multiple toes. Diagnosis was achieved by biopsy during amputation of the affected toes. Hepatic metastasis was identified at necropsy, with a similar gross appearance resembling an abscess.
Neoplasia is an uncommon finding in crocodilians and metastatic neoplasia is rarely documented. This is the first report of SCC in a crocodilian.
鳞状细胞癌（SCC）在爬行动物中并不常见，尽管人工饲养的澳大利亚鳄鱼数量有所增加，但关于其肿瘤形成的报道却很少。
我们报告了一例野生捕获的咸水鳄（湾鳄）后肢发生的局部浸润性鳞状细胞癌，并伴有肝转移。肉眼可见甲床附近软组织肿胀，进而发展为包含多个脚趾的脓肿。通过对受影响脚趾截肢时进行活检得以确诊。尸检时发现肝转移，其肉眼外观类似脓肿。
肿瘤在鳄鱼中并不常见，转移性肿瘤更是鲜有记录。这是关于鳄鱼鳞状细胞癌的首例报告。
