A pure Sertoli cell tumor of the testis in a 26-year-old man is reported, with cytologic, histologic and ultrastructural findings. The preoperative cytological diagnosis allowed a conservative surgical approach.

We report the case of an intrapericardial lesion with the pathological features of a multilocular cyst, found on the adventitia of an aortic aneurysm in a 62-yr-old man. Microscopically, it consisted of numerous cavities lined by flattened or cuboidal cells with the immunocytochemical and electron microscopical features of mesothelium, sometimes forming a hyperplastic pattern. Numerous nerve bundles and collections of inflammatory cells were present in the stroma. These features were consistent with a reactive lesion.

The cytologic, histologic, immunocytochemical and ultrastructural features of 2 cases of hyalinizing trabecular adenoma (HTA) of the thyroid are described. The difficulty of a cytologic diagnosis and the need for an immunohistochemical profile of the lesions for a final histologic diagnosis are emphasized.
