Although its morphology has been described in detail, the nature of the tumor and the occurrence of tissue is still controversial. In order to further study the source of SHL tissue, we select 39 cases of SHL specimens resected surgically, using immunohistochemical methods to study its clinicopathological features and histology, are as follows. 1 information and
