A fibrosarcoma of periosteal origin was identified in the oral cavity of a 22-yr-old male captive Siamese crocodile (Crocodylus siamensis). The diagnosis was based upon the gross and light microscopical examination. The mesenchymal histogenesis was derived from the capability of the cells to produce collagen fibers. The invasive growth and the polymorphous cells in combination with the low mitotic index suggest a low-order malignancy. Attempts by immunohistochemical staining techniques to identify the specific lineage of the neoplastic cells and the expressed collagen type were unsuccessful.
在一只22岁的圈养暹罗鳄(暹罗鳄属)雄性口腔中发现了一例骨膜起源的纤维肉瘤。诊断基于大体和光学显微镜检查。间充质组织发生源于细胞产生胶原纤维的能力。侵袭性生长、多形性细胞与低有丝分裂指数相结合提示为低级别恶性肿瘤。通过免疫组织化学染色技术鉴定肿瘤细胞的特定谱系和所表达的胶原类型的尝试未成功。
