Epithelioid hemangioendothelioma (EHE) is a rare tumor, first characterized by Sharon Weiss and Franz Enzinger in 1982 [1] that both clinically and histologically is intermediate between angiosarcoma and hemangioma. However, a distinct, disease-defining genetic alteration recently described for EHE indicates that it is an entirely separate ...
Epithelioid hemangioendothelioma is an uncommon vascular tumor of intermediate malignancy that was first described by Steven Billings, Andrew Folpe, and Sharon Weiss in 2003. [1] These tumors are so named because their histologic appearance resembles a proliferation of epithelioid cells, with polygonal shape and eosinophilic cytoplasm.
A hemangioma or haemangioma is a usually benign vascular tumor derived from blood vessel cell types. The most common form, seen in infants, is an infantile hemangioma, known colloquially as a "strawberry mark", most commonly presenting on the skin at birth or in the first weeks of life.
Differential diagnosis includes vascular malformation, angioma, pyogenic granuloma, angiosarcoma, epithelioid hemangioendothelioma, Kaposi’s sarcoma, and other more rare vascular tumors. Three forms of intravascular papillary endothelial hyperplasia exist: the primary or pure form, the secondary or mixed form, and the extravascular form.
Angiolymphoid hyperplasia with eosinophilia (also known as: [1] "Epithelioid hemangioma," "Histiocytoid hemangioma," "Inflammatory angiomatous nodule," "Intravenous atypical vascular proliferation," "Papular angioplasia," "Inflammatory arteriovenous hemangioma," and "Pseudopyogenic granuloma") usually presents with pink to red-brown, dome-shaped, dermal papules or nodules of the head or neck ...
Epithelioid may refer to: Epithelioid cell, a cell that resembles epithelial cells; Epithelioid sarcoma, a soft tissue tumour; Epithelioid hemangioendothelioma, a vascular tumour occurring in the lining of blood vessels; Epithelioid blue nevus, a melanocytic nevus; Epithelioid sarcoma-like hemangioendothelioma, a group of vascular neoplasms
Lashawn Thompson, 35, died on Sept. 13, 2022, at the Fulton County Jail in Atlanta, where he was found in a cell “eaten alive” by bedbugs and other insects, according to his family.
Cancer is a group of diseases that involve abnormal increases in the number of cells, with the potential to invade or spread to other parts of the body. [1] Not all tumors or lumps are cancerous; benign tumors are not classified as being cancer because they do not spread to other parts of the body. [1]
