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. [9]
One of the most important factors in classifying a tumor as benign or malignant is its invasive potential. If a tumor lacks the ability to invade adjacent tissues or spread to distant sites by metastasizing then it is benign, whereas invasive or metastatic tumors are malignant. [3] For this reason, benign tumors are not classed as cancer. [27]
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 ...
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.

A cavernous liver hemangioma or hepatic hemangioma is a benign tumor of the liver composed of large vascular spaces lined by monolayer hepatic endothelial cells. It is the most common benign liver tumour, and is usually asymptomatic and diagnosed incidentally on radiological imaging or during laparotomy for other intra-abdominal issues.
Multiple cutaneous hemangiomas or large facial hemangiomas are associated with a greater possibility of multiple organ involvement, or internal hemangiomatosis. [9] The liver is the most common organ involvement in diffuse neonatal hemangiomatosis, and its involvement can be determined through imaging and presence of hepatomegaly , or enlarged ...
