Abstract

A mesenchymal chondrosarcoma found in a 7-year-old Holstein cow was studied by light and electron microscopy. There was a primary site in the subcutaneous tissue at the base of the neck and metastases in the lungs, pleura, broncho-mediastinal lymph nodes, kidneys and heart. The neoplasm was composed of undifferentiated mesenchymal tissue, myxoid tissue and chondroid tissue. The neoplastic cells of the former two tissues were characterized by desmosome-like junctions and moderate to small amounts of rough endoplasmic reticulum (RER).

摘要

对一头7岁荷斯坦奶牛身上发现的间叶性软骨肉瘤进行了光镜和电镜研究。肿瘤原发部位在颈部基部的皮下组织，转移至肺、胸膜、支气管纵隔淋巴结、肾脏和心脏。肿瘤由未分化间叶组织、黏液样组织和软骨样组织组成。前两种组织的肿瘤细胞具有类桥粒连接以及中度至少量的粗面内质网（RER）。
