Xanthelasma in the form of XP can be diagnosed from clinical impression, although in some cases it may need to be distinguished (differential diagnosis) from other conditions, especially necrobiotic xanthogranuloma, syringoma, palpebral sarcoidosis, sebaceous hyperplasia, Erdheim–Chester disease, lipoid proteinosis (Urbach–Wiethe disease), and the syndrome of adult-onset asthma and ...
Ocular ischemic syndrome is the constellation of ocular signs and symptoms secondary to severe, chronic arterial hypoperfusion to the eye. [1] Amaurosis fugax is a form of acute vision loss caused by reduced blood flow to the eye; it may be a warning sign of an impending stroke, as both stroke and retinal artery occlusion can be caused by thromboembolism due to atherosclerosis elsewhere in the ...
Specifically, Touton giant cells are found in lipid-rich lesions such as those of fat necrosis, xanthoma, xanthelasma and xanthogranulomas. Touton giant cells are also referred to as xanthelasmatic cells due to the fact they are found in lesions associated with xanthomas which are skin growths with yellow, lipid filled deposits.
A xanthelasma is a sharply demarcated yellowish collection of cholesterol underneath the skin, usually on or around the eyelids. Strictly, a xanthelasma is a distinct condition, being called a xanthoma only when becoming larger and nodular, assuming tumorous proportions. [3] Still, it is often classified simply as a subtype of xanthoma. [4]
High cholesterol levels normally do not cause any symptoms. Yellow deposits of cholesterol-rich fat may be seen in various places on the body such as around the eyelids (known as xanthelasma palpebrarum), the outer margin of the iris (known as arcus senilis corneae), and in the tendons of the hands, elbows, knees, and feet, particularly the Achilles tendon (known as a tendon xanthoma).
The eruptive form typically presents on the anterior chest, abdomen, neck, and arms. It presents in successive crops with periods of relief in between times of active rash . The milia -like type of syringoma is typically smaller lesions that have a milky white center that can look like milia.
The two forms of vitelliform macular dystrophy each have characteristic changes in the macula that can be detected during an eye examination. In the Best disease , the paraclinic evaluations such as fundus fluorescein angiography or indocyanine green angiography , along with baseline and final electrooculography (EOG) results, may shed the ...
