Microscopically, most tumors are characterized by a granuloma-like pattern: nodules of spindled and epithelioid cells circumscribe areas of central hyalinization and necrosis.

Non-immune-mediated granuloma cells also express carboxypeptidase-M (CPM). (a and b) Besides epithelioid macrophages, foreign body giant cells (arrows) of lung amyliodoma (a) and surgical suture ...

Bronchial biopsy sections showing a well-formed epithelioid cell granuloma with surrounding lymphocytes. There is no caeseation, and no giant cells are present.

Tumor necrosis factor (TNF) alpha production within the granuloma guides the fusion of epithelioid histiocytes, forming the classic multinucleated giant cells. 5 Of interest, sarcoidal granulomas ...

External to the epithelioid cells is a circumferential layer of fibroblasts and a cuff of lymphocytes and mononuclear and plasma cells.

Histopathologic examination shows numerous granulomas of epithelioid histiocytes surrounded by a dense infiltrate of lymphocytes (hematoxylin and eosin staining, x5 original magnification).
