Epithelioid histiocytes (Epithelioid cells) are activated macrophages resembling epithelial cells:^[1] elongated, with finely granular, pale eosinophilic (pink) cytoplasm and central, ovoid nucleus (oval or elongate), which is less dense than that of a lymphocyte. 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.

Renal angiomyolipoma: a radiological classification and update on recent developments in diagnosis and management.

Jinzaki M1, Silverman SG, Akita H, Nagashima Y, Mikami S, Oya M.
Abdominal imaging.Abdom Imaging.2014 Jun;39(3):588-604. doi: 10.1007/s00261-014-0083-3.
Angiomyolipoma is the most common benign solid renal neoplasm observed in clinical practice. Once thought to be a hamartoma and almost always diagnosed by the imaged-based detection of fat, angiomyolipomas are now known to consist of a heterogeneous group of neoplasms. Although all are considered pe
