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.
Kaposiform hemangioendothelioma. Kaposiform hemangioendotheliomas (KHEs) are borderline, locally destructive vascular tumors. [4] They are named after their resemblance to the lesions of Kaposi's sarcoma. [13] KHEs are described as locally destructive because they can infiltrate underlying muscle and fat. [4]
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 ...
U.S. Surgeon General Dr. Vivek Murthy warned in a recent advisory about alcohol use increasing cancer risk. The advisory notes that alcohol can increase the risk of throat, liver, esophageal ...
Other symptoms to note: Drug rashes can be a side effect of or a reaction to a new medication; almost any medication can cause a drug rash, but antibiotics and NSAIDs are the most common culprits ...
Depending on the grade of the sarcoma, it is treated with surgery, [8] chemotherapy, and/or radiotherapy.Though surgery is the current standard of care for hemangiopericytomas, metastasis and tumor recurrence occur in more than 30% of patients, in particular recurrence in the pelvis and retroperitoneum [3] and metastasis in bone and lungs.
