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 ...
[7] [8] The lesion usually presents as a slow-growing tumor of the skin and subcutaneous tissues [9] of the head, neck, or extremity, of infants or young children. [ 2 ] : 601 However, EPA has involved the testicle , [ 6 ] [ 9 ] deep muscle tissue as a neoplastic transformation of a larger existing benign cavernous hemangioma , [ 10 ] bone [ 11 ...
In some cases, they may affect an entire extremity such as a hand or foot. Although they are usually painless, the patient may feel mild pain when pressure is exerted on the area. They come in the colors white, pink, red, blue, purple, and black; and the pain lessens the lighter the color of the bump.
Klippel–Trénaunay syndrome, formerly Klippel–Trénaunay–Weber syndrome [1] and sometimes angioosteohypertrophy syndrome and hemangiectatic hypertrophy, [2] is a rare congenital medical condition in which blood vessels and/or lymph vessels fail to form properly.
[10] The most common type of reactive proliferative tumors are pyogenic granulomas also known as lobular capillary hemangiomas, that are more often found in children and young adults. [4] These granulomas are well defined growths of less than a centimetre across. They are bright red due to being highly vascularised, and bleed and ulcerate ...
It may mimic an angiosarcoma, with lesions that are red or purplish 5-mm to 5-cm papules and deep nodules on the head, neck, or upper extremities. [1] [2]: 592 The cause of intravascular papillary endothelial hyperplasia is unknown. Risk factors include a history of local trauma or prior vascular disorders.
A dermatofibroma, or benign fibrous histiocytomas, is a benign nodule in the skin, typically on the legs, elbows or chest of an adult. [3] It is usually painless. [3] It usually ranges from 0.2cm to 2cm in size but larger examples have been reported. [3] It typically results from mild trauma such as an insect bite. [3]
Although the precise etiology of targetoid hemosiderotic hemangioma is uncertain, trauma has been suggested as one of the primary causes of the targetoid look. [ 8 ] [ 9 ] Trauma may result in the production of microshunts, wherein the capillary pressure fills the lesion's lymph spaces with erythrocytes , hence promoting the formation of ...
