What are telangiectatic nevi? Small areas of discoloration may appear on a newborn, caused by the way certain blood vessels form. The formal name for these marks is telangiectatic nevi. Common names for these birthmarks include angel kisses and stork bites. Although parents often worry that these will last a lifetime or grow darker, these marks often grow lighter and disappear as children age.

- Non-arteritic anterior ischemic optic neuropathy (NAION) is due to impaired circulation of blood to the front of the optic nerve. It is called “non-arteritic” because there is reduced blood flow without true inflammation of the blood vessels (as there is in arteritis).t is called “ischemic” because that is the word that describes injury due to reduced blood flow. Finally, it is called an “optic neuropathy” because it is an injury to the optic nerve, which disrupts the ability of eye to send information to the brain.

Hereditary hemorrhagic telangiectasia Hereditary hemorrhagic telangiectasia is a disorder that results in the development of multiple abnormalities in the blood vessels. In the circulatory system, blood carrying oxygen from the lungs is normally pumped by the heart into the arteries at high pressure.

Pathology of Dysplastic (Atypical) Melanocytic Nevi The clinical and histologic differential diagnosis of dysplastic (atypical, Clark) melanocytic nevi include common nevi, melanoma, Spitz nevi, nevi of special sites, and melanoma in association with a dysplastic nevus. Partial biopsies of large, pigmented lesions may show dysplastic nevuslike features.

Telangiectasia Telangiectasias, also known as spider veins, are small dilated blood vessels[1] near the surface of the skin or mucous membranes, measuring between 0.5 and 1 millimeter in diameter.[2]

- It is composed of over 1 million neurons. Damage to the optic nerve is called optic neuropathy. Ischemic optic neuropathy (ION) is a sudden loss of central vision and/or side vision because of poor blood flow to the optic nerve (figure 1).There are two main forms of ION, arteritic (aka Temporal arteritis) and nonarteritic (aka NAION).schemic optic neuropathy (ION) is a sudden loss of central vision and/or side vision because of poor blood flow to the optic nerve (figure 1). There are two main forms of ION, arteritic (aka Temporal arteritis) and nonarteritic (aka NAION).

Birthmark Colloquially called a stork bite, angel's kiss or salmon patch, telangiectatic nevus appears as a pink or tanned, flat, irregularly shaped mark on the knee, back of the neck, and/or the forehead, eyelids and, sometimes, the top lip. little over 1 in 10 babies have a vascular birthmark present by age 1. Several birthmark types are part of the group of skin lesions known as nevi or naevi, which means birthmarks in Latin. The exact cause of most birthmarks is unknown, but vascular birthmarks are not hereditary.

- Telangiectasia is a benign skin condition that can occur in otherwise healthy people. In some cases, it may be a symptom of serious illness. The causes of telangiectasia are unknown, but researchers think they may be genetic, environmental, or a combination of both. It’s believed the most common causes of telangiectasia are chronic exposure to the sun and extreme heat or cold.

Gastric Antral Vascular Ectasia (Watermelon Stomach) Watermelon Stomach may occur in systemic scleroderma but not in localized scleroderma, such as Linear and Morphea. Watermelon Stomach is the popular name for Gastric Antral Vascular Ectasia (GAVE) — a condition in which the lining of the stomach bleeds, causing it to look like the characteristic stripes of a watermelon when viewed by Endoscopy. (It is not a large, bloated or fat stomach as some people think it is.)

Hereditary Hemorrhagic Telangiectasia (HHT) Hereditary Hemorrhagic Telangiectasia is an inherited condition that can result in patients having arteriovenous malformations (artery to vein direct connection with no capillaries in between). These malformations can be very small and called “telangiectasias” or they can be large and called “AVMs” (arteriovenous malformations).

Hereditary hemorrhagic telangiectasia Juvenile polyposis/hereditary hemorrhagic telangiectasia syndrome is a condition that involves both arteriovenous malformations and a tendency to develop growths (polyps) in the gastrointestinal tract. Hereditary hemorrhagic telangiectasia types 1, 2 and 3 do not appear to increase the likelihood of such polyps.

- Background. Nevus araneus, also known as spider angioma or spider nevus, is a common benign vascular lesion present in 10-15% of healthy adults and young children. They may appear as a solitary or multiple lesions.pider angiomas (nevus araneus) also may produce significant cosmetic concerns in some patients. Although a finding of 5 or more spider nevi is common in children with liver disease, this quantity can also be present in many healthy children.

Pathology of Dysplastic (Atypical) Melanocytic Nevi Dysplastic (atypical, Clark) melanocytic nevi occur in the setting of sporadic and familial melanomas and are an important risk factor in development of cutaneous melanoma. Increased numbers of clinically dysplastic (atypical, Clark) melanocytic nevi are associated with a greater risk for melanoma. A single, clinically dysplastic (atypical, Clark) melanocytic nevi has a 2-fold increased risk, whereas greater than 10 clinically dysplastic (atypical, Clark) melanocytic nevi are associated with a 12-fold risk for melanoma.

ataxia-telangiectasia The disorder first appeared in the medical literature in the mid-1920s, but was not named specifically until 1957. The name is a combination of two recognized abnormalities: ataxia (lack of muscle control) and telangiectasia (abnormal dilatation of capillary vessels that often result in tumors and red skin lesions).

"Posttraumatic Sympathicotonia and Raynaud's of the Hands Secondary to Thoracic Outlet Syndrome: The ""Blue Hands"" Syndrome" Infrared thermography is a most useful clinical diagnostic tool for sustained sympathicotonia of the hands due to costoclavicular thoracic outlet syndrome. When the patient presents with blue, cyanotic hands with vasomotor and sudomotor disturbance, thermography will provide the clinician with invaluable information.

- Ataxia-telangiectasia is a rare inherited disorder that affects the nervous system, immune system, and other body systems.taxia-telangiectasia is inherited in an autosomal recessive pattern, which means both copies of the ATM gene in each cell have mutations. Most often, the parents of an individual with an autosomal recessive condition each carry one copy of the mutated gene, but do not show signs and symptoms of the condition.

nevus nevocytic nevus (nevus cell nevus) the most common type of nevus, usually more or less hyperpigmented, initially flat but soon becoming elevated, composed of nests of nevus cells. These nevi are classified as compound, intradermal, or junction according to the histologic pattern and location of nevus cells.

- Recording this finding may be useful for epidemiologic studies or when a reexcision is performed and it is difficult to decide if the residual lesion is an associated benign melanocytic nevus or melanoma (especially in cases of melanomas arising in cellular blue nevi or deep-penetrating nevi).

Telangiectasia macularis eruptiva perstans Telangiectasia macularis eruptiva perstans (TMEP), which was described by Parkes Weber in the 1930s, represents a rare form of mastocytosis [1]. The lesions typically consist of telangiectatic macules and have a background color ranging from tan to brown.
