Impetigo is most common in young children but can occur at any age. It is usually transmitted through direct contact. Risk factors which may predispose an individual to impetigo include: Skin conditions: atopic dermatitis, contact dermatitis, scabies, chickenpox. Skin trauma: lacerations, insect bites, thermal burns, abrasions. Immunosuppression.
Clinical features. Impetigo is due to localised, superficial and non-follicular infection with Staphylococcus aureus &/or Streptococcus pyogenes. Ecthyma is a deeper infection due to the same organisms. Staphylococcal impetigo is characterised by surface honey-yellow crusting or blisters. It tends to be itchy.
Impetigo is a common superficial bacterial infection of the skin. Streptococcus and/or Staphylococcus species are the usual causative organisms. Histology of impetigo. There are two clinical forms: bullous and common. The common type is rarely biopsied. The bullous form of impetigo shows a subcorneal bulla with a dermal inflammatory response
A blistering disease is a condition in which there are fluid-filled skin lesions. Vesicles are small blisters less than 5 mm in diameter. A bulla is a larger blister. Note that the plural of bulla is bullae. Blisters may break or the roof of the blister may become detached forming an erosion. Exudation of serous fluid forms crust.
Impetigo of other sites. View pictures of impetigo (school sores) in the gallery below. Impetigo is a common, superficial, highly contagious bacterial skin infection characterised by honey-coloured crusted erosions and pustules.
Bullous pemphigoid is the most common autoimmune dermatosis presenting with crops of tense pruritic blisters, often in older adults. Mucosal involvement may occur and a number of clinical subtypes exist. Autoantibodies are directed to components of the basement membrane, particularly the BP antigens BP180 and BP230.
Bullous pemphigoid causes severe itch and (usually) large, tense bullae (fluid-filled blisters), which rupture forming crusted erosions. Other variable features include: Bullous pemphigoid typically involves the flexor aspects of the limbs. It may be localised to one area, or widespread on the trunk and proximal limbs.
The unilateral development of superficial, blistering lesions that are rupturing to produce honey-coloured crusted lesions is highly suggestive of bullous impetigo. The condition is infectious and spreads by both fomites and direct skin-to-skin contact.
Bullous impetigo; Drug hypersensitivity reaction; Viral exanthem; Thermal burns. What is the treatment for staphylococcal scalded skin syndrome? SSSS is considered a dermatological emergency which requires hospitalisation and prompt treatment. This usually involves: Intravenous antibiotics
This page describes vesiculobullous and pustular lesions in newborns and their differentiating characteristics. A neonate is a newborn baby under 28 days of age. Vesicles are small blisters containing clear fluid. Bullae are large blisters containing clear fluid. Pustules are circumscribed lesions that contain dense cellular content.
