plates<\/span> in places exposed to the sun.<\/p>\nIt occurs most often in light-skinned, middle-aged women who live in sunny climates. There is a debate about whether it is a different entity or a variant of granuloma annulare.<\/p>\n
It is also known as O'Brien granuloma after the doctor who first described it.<\/p>\n\n<\/span>Actinic granuloma<\/span><\/h5>\n<\/section>\n\n\n

<\/span>What is the cause of actinic granuloma?<\/span><\/h2>\nActinic granuloma is believed to be inflammatory<\/span> response to sun damage, possibly to injuries elastic fibers<\/span>. White blood cells known as Helper T-lymphocytes<\/span> are predominantly involved.<\/p>\n\n

<\/span>What are the clinical characteristics of actinic granuloma?<\/span><\/h2>\nActinic granuloma begins as flesh-colored or pink papules<\/span> (small bumps) that fusion<\/span> in annular plates (larger thick patches) ranging in size from 1 to 10 cm in diameter. The plaques typically have raised red edges and a slightly thinned pale central area.<\/p>\nThe lesions usually produce no symptoms, but when exposed to the skin they can become red and uncomfortable.<\/p>\n
<\/span>How is actinic granuloma diagnosed?<\/span><\/h2>\nThe clinical diagnosis of actinic granuloma is suspected when there is an annular dermal<\/span> license plate<\/span> on the sun exposed skin<\/span>. The diagnosis is often compatible with the typical histopathological<\/span> features on the skin biopsy<\/span>.<\/p>\n<\/span>\nDifferential diagnosis<\/span> actinic granuloma<\/span><\/h2>\nActinic granuloma is difficult to distinguish from others granulomatous<\/span> disorders, particularly granuloma annulare and necrobiosis<\/span> lipoidica<\/p>\n\n

<\/span>What is the treatment of actinic granuloma?<\/span><\/h2>\nSun protection is important to reduce the chance of further injury.<\/p>\n
Treating actinic granuloma can be difficult. Infiltration<\/span> of corticosteroids in the elevated border, phototherapy and antimalarials are largely ineffective.<\/p>\nIsotretinoin and acitretin have been used with varying success, and there are case reports of success with cyclosporine.<\/p>\n<\/section>","protected":false},"excerpt":{"rendered":"
