A Sertoli cell nodule, also Pick's adenoma, testicular tubular adenoma and tubular adenoma of the testis, is a benign proliferation of Sertoli cells that arises in association with cryptorchidism (undescended testis). They are not composed of a clonal cell population, i.e. neoplastic; thus, technically, they should not be called an ''adenoma''. ==Pathology== Sertoli cell nodules are unencapsulated nodules that consist of:〔 #cells arranged in well-formed tubules (that vaguely resemble immature Sertoli cells), with #bland hyperchromatic oval/round nuclei that are stratified, and #may contain eosinophilic (hyaline) blob in lumen (centre). 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Sertoli cell nodule」の詳細全文を読む スポンサード リンク
