They have indistinct shape contour, often appear to merge into one another and can form aggregates known as giant cells. ==Clinical significance== Epithelioid cells are an essential characteristic of granulomas: that is to say that without them a histological finding is not a granuloma. A granuloma can be defined as "an organized collection of epithelioid macrophages." A non-purist would give a broader definition of the granuloma as "an organized collection of macrophages." The latter definition would include mere collections of giant cells surrounding inert substances like suture material – the so-called "non-immune granulomas." Granuloma formation is a strategy that has evolved to deal with those pathogens that have learned to evade the host immune system by various means like resisting phagocytosis and killing within the macrophages. Granulomas try to wall off these organisms and prevent their further growth and spread. Many old scourges of mankind like tuberculosis, leprosy and syphilis fall into this category of diseases. Granuloma formation is also the feature of many of our newer problems like fungal infections, sarcoidosis and Crohn's disease. 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「Epithelioid cell」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
