Histologically, SRMS was characterized by the presence of large amounts of heavily hyalinized matrix, mimicking osteoid or chondroid tissue. 镜下以含有大量玻璃样变的基质为特征,类似原始的骨样组织或软骨样基质。
Results The tumor had local area of differentiated chondroid tissue. 结果肿瘤组织出现灶性软骨分化。
Conclusion: The gene expression of BMP-2 might play an important role in the formation of chondroid tissue in PA of human parotid gland. 结论:BMP-2基因的表达可能参与腮腺多形性腺瘤中软骨样组织形成的病理过程。
