Abstract
A case of bilateral testicular simple cysts was seen in a 79-year-old Chinese man. The cysts contained clear fluid and were lined with simple cuboidal epithelia. The histochemical and immunohistochemical findings of this case were presented with an effort to clarify the nature of the cyst. In addition, the clinicopathological features, differential diagnosis and proposed histogenesis of the documented testicular simple cysts in the literature were also reviewed.
