A pyogenic granuloma or lobular capillary hemangioma [3] is a vascular tumor that occurs on both mucosa and skin, and appears as an overgrowth of tissue due to irritation, physical trauma, or hormonal factors. [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]
An infantile hemangioma (IH), sometimes called a strawberry mark due to appearance, is a type of benign vascular tumor or anomaly that affects babies. [1] [2] Other names include capillary hemangioma, [6] "strawberry hemangioma", [7]: 593 strawberry birthmark [8] and strawberry nevus.
A petechia (/ p ɪ ˈ t iː k i ə /; [1] pl.: petechiae) is a small red or purple spot (≤4 mm in diameter) that can appear on the skin, conjunctiva, retina, and mucous membranes which is caused by haemorrhage of capillaries. [2] [3] The word is derived from Italian petecchia ' freckle ', of obscure origin. [1]
The concept that capillary blood, obtained from pricking the heel or finger and blotted onto filter paper, could be used to screen for metabolic diseases in large populations of neonates was introduced in Scotland by Robert Guthrie in 1963. Neonatal screening for phenylketonuria became nationwide in 1969–70.
A capillary is a small blood vessel, from 5 to 10 micrometres in diameter, and is part of the microcirculation system. Capillaries are microvessels and the smallest ...
A port-wine stain is a capillary malformation, seen at birth. [2] Port-wine stains persist throughout life. [3] The area of skin affected grows in proportion to general growth. Port-wine stains occur most often on the face but can appear anywhere on the body, particularly on the neck, upper trunk, arms and legs.
Emissions from the radionuclide indicate amounts of blood flow in the capillaries of the imaged regions. In the same way that a plain X-ray is a 2-dimensional (2-D) view of a 3-dimensional structure, the image obtained by a gamma camera is a 2-D view of 3-D distribution of a radionuclide .
Angiokeratoma of Fordyce (also known as "Angiokeratoma of the scrotum and vulva," though not to be confused with Fordyce's spots) [5] is a skin condition characterized by red to blue papules on the scrotum or vulva. Solitary angiokeratoma is a small, bluish-black, warty papule that occurs predominantly on the lower extremities. [5]: 590
