Loosely cohesive epithelioid cells
separated by extracellular myxoid matrix are present in this myxoinflammatory fibroblastic sarcoma (hematoxylin-eosin, original magnification X200).
A novel member of the family of lesions characterized by the presence of perivascular epithelioid cells
The granulomas in all cases seen so far in camels are of the lepromatous type and characterized by the presence of foamy poorly basophilic macrophages and epithelioid cells
that contain large numbers of acid fast bacilli in liver surrounded by a fibrous capsule.
Old scar tissues are infiltrated with noncaseating epithelioid cell
granulomas in scar sarcoidosis (4).
On lymph node biopsy sections caseating granulomas were seen in 91% cases, non-caseating granulomas in 5%, a collection of epithelioid cells
with rest of the lymph node showing reactive changes in 2% and caseation necrosis only in 2%.
Forty (76%) of the tumours consisted of spindle-shaped cells, and 5 (9%) of epithelioid cells
Presence of macrophages, epithelioid cells
and langhans type of giant cells were predominantly found.
Histologic examination of lung, lymph nodes, spleen, liver, and brain showed granulomatous inflammation with predominantly macrophages, epithelioid cells
(in the lung, including bronchioles), and some multinucleated giant cells.
Histologic examination demonstrated epithelioid cells
arranged in papillae, cords and solid nests.
Tissue sections demonstrate a relatively heterogeneous mass composed of trabecular bone, osteoid matrix, cartilage, and spindle cells admixed with epithelioid cells
As they described, GP is a rare neuroendocrine tumor comprising epithelioid cells
, spindle-shaped cells, and ganglionlike cells and this neuroendocrine tumor commonly arises from the duodenum.
This observation clearly suggests that when necrosis is seen with or without neutrophils, tuberculosis should be considered and epithelioid cells
