Microbiology
- Trichophyton Rubrum
Interestingly, nevus anemicus has been reported to be resistant to dermatophyte infections such as Trichophyton rubrum, which was postulated to be due to the reduced blood flow and lower temperature of the lesional skin. [ncbi.nlm.nih.gov]
- Malassezia Furfur
If tinea versicolor is suspected, potassium hydroxide (KOH) examination of lesional skin should be performed, which would show the characteristic "spaghetti and meatballs" appearance of Malassezia furfur hyphae and spores respectively. [ncbi.nlm.nih.gov]
Treatment
Treatment Self-care: To make the patches more aesthetically favorable, one can use cosmetics to cover them up. Medication: There are no medications or treatments for this disorder as it is benign, subtle, and asymptomatic. [mfine.co]
Treatment Options There are no recommended treatment options, as nevus anemic is benign, asymptomatic, and subtle. Cosmetic make-up can make the nevus more aesthetically pleasing when needed. [dermatologyadvisor.com]
Since the histopathology of nevus anemicus is normal, nevus anemicus is a pharmacologic nevus and not an anatomic one.[23] No treatment is required. [journals.lww.com]
(July 2018) Treatment[edit] Since the histopathology of nevus anemicus is normal, nevus anemicus is a pharmacologic nevus and not an anatomic one.[8][9] In most people a nevus anemicus is on a covered area and so light in appearance that no treatment [en.wikipedia.org]
Prognosis
Prognosis The prognosis of nevus anemicus is excellent. Lesions of nevus anemicus usually persist unchanged throughout life. They are asymptomatic. [emedicine.medscape.com]
Etiology
No etiological mechanism can be suggested. © 1981 S. [karger.com]
Etiology Nevus anemicus is due to a congenital anomaly of the cutaneous vasculature resulting in hypersensitivity to catecholamines, leading to localized vasoconstriction. [emedicine.medscape.com]
Etiology Pathophysiology NA is a nonmelanotic disorder caused by localized hypersensitive alpha-adrenergic receptor sites of cutaneous arterioles to catecholamines, inducing active vasoconstriction. [dermatologyadvisor.com]
Introduction Nevus anemicus is an uncommon, congenital vascular malformation resulting in hypopigmented cutaneous macules and/or patches that characteristically do not create erythema in response to trauma, heat, or cold.[1][2][3][4] Etiology Nevus anemicus [ncbi.nlm.nih.gov]
Epidemiology
Epidemiology Frequency The prevalence of nevus anemicus in several research control groups was documented at 1-2%. [2] Race No racial predilection has been noted in the literature for nevus anemicus. [emedicine.medscape.com]
Epidemiology The prevalence of nevus anemicus in dermatology research control groups has been estimated to be 1% to 2%. [ncbi.nlm.nih.gov]
Pathophysiology
The probable pathophysiology of the nevus was discussed.) Libow, LF. “Phakomatosis pigmentovascularis type IIIb”. J Am Acad Dermatol. vol. 29. 1993. pp. 305-7. [dermatologyadvisor.com]
Pathophysiology Intralesional injection of bradykinin, acetylcholine, serotonin, nicotine, 5-hydroxytryptamine, and histamine fails to induce the anticipated vasodilatation or erythema in the affected area. [emedicine.medscape.com]
Pathophysiology Nevus anemicus is attributed to the increased sensitivity of cutaneous blood vessels to catecholamines such as epinephrine (adrenaline) and norepinephrine (noradrenaline). [ncbi.nlm.nih.gov]
