Langhans giant cells (LGC) are giant cells found in granulomatous conditions. They are formed by the fusion of epithelioid cells ( macrophages ), and contain nuclei arranged in a horseshoe-shaped pattern in the cell periphery.
A giant cell (also known as a multinucleated giant cell, or multinucleate giant cell) is a mass formed by the union of several distinct cells (usually histiocytes), often forming a granuloma. [ 1 ] Although there is typically a focus on the pathological aspects of multinucleate giant cells (MGCs), they also play many important physiological roles.
Langerhans cell is represented by a yellow oval; blue arrows correspond to is_a relations, and orange arrows correspond to develops_from relations. Only a subset of Langerhans cell parent types are included in the figure. [1] A Langerhans cell (LC) is a tissue-resident macrophage of the skin [2] once thought to be a resident dendritic cell. [3]
A foreign-body giant cell is a collection of fused macrophages which are generated in response to the presence of a large foreign body. This is particularly evident with catheters , parasites , or biomaterials that are inserted into the body for replacement or regeneration of diseased or damaged tissues.
According to Kukushkin, the memories stored in non-brain cells in other parts of the body are memories strictly related to the roles that those specific cells play in human health. Thus, he detailed:
Giant cells, specifically Langhans giant cells, are often seen in sarcoidosis. [96] Schaumann bodies seen in sarcoidosis are calcium and protein inclusions inside of giant cells as part of a granuloma. [97] Asteroid bodies can be seen in sarcoidosis. [97]
Epithelioid cell granuloma can be defined as specifically and structurally organized collection of epithelioid cells, macrophages, lymphocytes and dendritic cells. Foreign-body granulomas may be considered an organized collection of macrophages, including mere collections of giant cells surrounding inert substances like suture material – the ...
Crystalline inclusion with developing Schaumann body, polarized, in sarcoidosis. In pathology, Schaumann bodies are calcium and protein inclusions inside of Langhans giant cells as part of a granuloma. Many conditions can cause Schaumann bodies, including: Sarcoidosis, Hypersensitivity pneumonitis, and; Berylliosis.
