The center of the lesion consists of macrophages and epithelioid cells.

The term epithelioid cell also refers to a specialized cell type of the immune system.

The nodules are composed of epithelioid cells and giant cells surroundeded by lymphocytes.

Epithelioid cell histiocytoma is a rare skin condition that is considered to be a variant of a dermatofibroma.

Clinical features, including prominent tumor vascularity, rapid growth, and heterogeneous pigmentation, are associated with an epithelioid cell component.

"It's got giant cells and epithelioid cells, the sine qua non of a granuloma.

Added Perivascular epithelioid cell neoplasms (PEComas) as a new subsection.

A tumour of this kind is known as a PEComa, from the initials of perivascular epithelioid cell.

Spitz nevus is also known as spindle and epithelioid cell nevus and juvenile melanoma.

The mammalian Leydig cell is a polyhedral epithelioid cell with a single eccentrically located ovoid nucleus.

Epithelioid cells are an essential characteristic of granulomas: that is to say that without them a histological finding is not a granuloma.

Unlike epithelial cells, however, epithelioid cells make contacts over their entire surface, rather than at restricted (e.g., basolateral) portions.

They are formed by the fusion of epithelioid cells (macrophages), and contain nuclei arranged in a horseshoe-shaped pattern in the cell periphery.

While InlB is necessary for Listeria internalisation in several other cell types, including hepatocytes, fibroblasts, and epithelioid cells.

PECs consist of perivascular epithelioid cells with a clear/granular cytoplasm and central round nucleus without prominent nucleoli.

Foreign materials are walled off by macrophages that may metamorphose into epithelioid cells, which are encircled by mononuclear leukocytes, forming granulomas.

These concentric corpuscles are composed of a central mass, consisting of one or more granular cells, and of a capsule formed of epithelioid cells.

This group also showed limited morhogenesis in 10% grafts of an immortalised postnatal epithelioid cell line [IEC-17], when combined with fetal mesenchyme.

Armah HB, Parwani AV: Perivascular epithelioid cell tumor.

Mutton-fat KPs are large in shape and are greasy-white in color and are formed from macrophages and epithelioid cells.

An epithelioid cell is a cell that resembles epithelial cells in that it directly contacts its neighboring cells via cell surface molecules or junctions.

Perivascular epithelioid cell - a cell seen in a various tumours and some non-tumour conditions (e.g. angiomyolipoma, PEComa, lymphangioleiomyomatosis)

Angiomyolipomas are tumours consisting of perivascular epithelioid cells (cells which are found surrounding blood vessels and which resemble epithelial cells).

This consists of giant multinucleated cells and (Langhans cells), surrounded by epithelioid cells aggregates, T cell lymphocytes and fibroblasts.
