malignant peripheral nerve sheath tumor
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.
cell tumors are rare mesenchymal tumors composed of histologically and immunohistochemically distinctive perivascular epithelioid
Histological examination revealed a tumor composed predominantly of epithelioid
cells set in a myxohyaline stroma spanning the entire dermis [Figure 1]c.
skin testing with a dilute solution of nerve in saline produced an epithelioid
cell granuloma, in which the cytoplasm contained dilated rough endoplasmic reticulum filled with an electron-dense product.
After surgical resection and histopathologic evaluation, a malignant nodular stage of an epithelioid
cortical-type thymoma was diagnosed.
There are several histologic forms of AE such as epithelioid
AE, Kaposiform AE, and myoid AE.
Activated macrophages transform into epithelioid
In dermis an inflammatory infiltrate composed predominantly by clusters of epithelioid
cells on a background of vacuolated histiocytes.
However, the case referred for consultation at yet another facility, which instead diagnosed the lesion as an epithelioid
malignant neoplasm, favoring carcinoma over epithelioid
sarcoma, according to the study.
Angiomyolipomas (AMLs) are the most common mesenchymal renal neoplasms and are classified as neoplasms of perivascular epithelioid
angiosarcoma is a variant of angiosarcoma composed of large rounded epithelioid
endothelial cells that are positive for cytokeratin on immunostaining.
