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 ...

In these dysfunctional cells pVHL cannot degrade HIF-1α, causing it to accumulate. HIF-1α causes the production of vascular endothelial growth factor, platelet derived growth factor B, erythropoietin and transforming growth factor alpha, which act to stimulate growth of cells within the tumor. [4]
Cherry angioma, also called cherry hemangioma [1] or Campbell de Morgan Spot, [2] is a small bright red dome-shaped bump on the skin. [3] It ranges between 0.5 – 6 mm in diameter and usually several are present, typically on the chest and arms, and increasing in number with age. [3] [4] If scratched, they may bleed. [5]

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 ...
