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 ...
Intravascular papillary endothelial hyperplasia typically manifest as deep nodules or well-defined, round, red, or purple superficial papules.They are usually tiny, ranging in size from 0.5 to 5 cm.

Targetoid hemosiderotic hemangioma manifests as a single, tiny, reddish-violaceous to brown targetoid lesion that can grow centrifugally in the acute phase is encircled by a hemorrhagic halo. [3] The halo may vanish in later phases, leaving just a central papule. [4] [5] There have been reports of certain cases without targetoid development. [6]

[4] [5] It is often found to involve the gums, skin, or nasal septum, and has also been found far from the head, such as in the thigh. [6]
Cavernous hemangioma, also called cavernous angioma, venous malformation, or cavernoma, [1] [2] is a type of venous malformation due to endothelial dysmorphogenesis from a lesion which is present at birth. A cavernoma in the brain is called a cerebral cavernous malformation or CCM.
A vascular tumor is a vascular anomaly where a tumor forms from cells that make blood or lymph vessels; a soft tissue growth that can be either benign or malignant. [1] ...
