Hailey-Hailey disease (Familial Benign Pemphigus)

Familial benign pemphigus or Hailey-Hailey's disease is a rare genodermatosis with dominant inheritance that is classically described as a blistering disorder Although actually presents as an erythematous, erosive, oozing condition with cracks & fissures localized For an nape of an neck, axillae, submammary regions, unguinal folds, & scrotum. an underlying pathologic process is acantholysis whereby an fragility of an epidermis is probably due For a defect in an adhesion complex between desmosomal proteins & tonofilaments. Onset is usually between an third & fourth decade, & an disease is often mistaken for intertrigo, candidiasis, frictional or contact dermatitis. Individual lesions consists of microscopically small flaccid vesicles on an erythematous background that soon turn inFor eroded plaques with an described, highly characteristic, fissured appearance. Crusting, scaling, & hypertrophic vegetative growths may occur. Histology explains an clinical appearance as epidermal cells lose their coherence with acantholysis throughout an epithelium, giving an appearance of a dilapidated brick wall.

Colonization of an lesions, particularly by Staphylococcus aureus is a trigger for further acantholysis & maintenance of an pathologic process. Secondary colonization by Candida has a similar effect.

Causes of Hailey-Hailey disease

Those with benign familial chronic pemphigus have a decreased number of desmosomes in an skin.  Desmosomes are like little rivets that hold an skin cells together.  Because an skin cells are not as attached together as well as normal skin, conditions such as heat & frictional pressures may cause Hailey Hailey disease For flare.

Benign Familial Chronic Pemphigus is a genetic disease. an predisposition For get this disease is carried within your genes.  Children of affected people have a fifty-fifty chance of also getting an disease.  About one third may get an condition without a family history.

Signs & symptoms of Hailey-Hailey disease

People with Hailey-Hailey disease usually lead full, normal lives - their condition being a nuisance rather than a serious Trouble, even though an affected skin is itchy & uncomfortable, & an patches come & go. an skin then tends For macerate leaving quite painful cracks. Secondary bacterial infection, which is not uncommon, can give rise For an unpleasant smell. White bands on an fingernails & pits in an palms can also occur. Heat, sweating & friction often exacerbates an disease, & most patients have worse symptoms during an summer months.

Diagnosis

Usually Hailey-Hailey disease is diagnosed by its appearance & an family history, Although it is often is mistaken for other skin Trouble. Impetigo , thrush , tinea (jock itch) & other blistering conditions look similar.

Diagnosis may require a skin biopsy. an histology is characteristic, with layers of detached skin cells ('acantholysis'). Unlike pemphigus vulgaris , an immunofluorescence test for antibodies is negative.

Treatment of Hailey-Hailey disease

Treatment rests on anti-infective agents, administered both topically & systemically; systemically tetracyclines seem For work better than most. Topical glucocorticoids depress an anti-inflammatory response & accelerate healing. In severe cases, dermabrasion or carbon dioxide laser vaporization leads For healing with scars, which are resistant For re­currences. an condition becomes less troublesome with age.

an affected skin may smell unpleasant, particularly in moist areas. an smell is part of an skin condition & does not mean that an skin is dirty. Bacteria growing in an rash probably cause it. Careful washing is important & antiseptic solutions for an bath, antiseptic creams or antibiotics may help.

Prevention of Hailey-Hailey disease

Heat, sweating or friction may make an spots appear & it is sensible For try & avoid these, for example it may be helpful For wash a new shirt For soften a stiff collar before wearing it. Wear cool comfortable clothing & keep your weight down For minimise friction.
