Superficial burn; Partial thickness burn; Full thickness burn; Depending on the type of burn that has occurred, there will be different signs and symptoms. A superficial burn has damaged the epidermis, and this appears as redness. A partial thickness burn has damaged the epidermis and underlying dermis, and is red, painful and often blisters
Burns that affect only the superficial skin layers are known as superficial or first-degree burns. [ 2 ] [ 11 ] They appear red without blisters, and pain typically lasts around three days. [ 2 ] [ 11 ] When the injury extends into some of the underlying skin layer, it is a partial-thickness or second-degree burn . [ 2 ]
Some examples of common fungal skin infections include: Dermatophytosis, also known as ringworm, is a superficial fungal infection of the skin caused by several different species of fungi. The fungal genera which cause skin infections in humans include Trichophyton, Epidermophyton, and Microsporum. [21]
Bacterium-related cutaneous conditions often have distinct morphologic characteristics that may be an indication of a generalized systemic process or simply an isolated superficial infection. [69] [70] Aeromonas infection; African tick bite fever; American tick bite fever (Rickettsia parkeri infection) Arcanobacterium haemolyticum infection

Venous skin ulcers that may appear on the lower leg, above the calf or on the lower ankle usually cause achy and swollen legs.
SSSS is a clinical diagnosis. This is sometimes confirmed by isolation of S. aureus from blood, mucous membranes, or skin biopsy; however, these are often negative. Skin biopsy may show separation of the superficial layer of the epidermis (intraepidermal separation), differentiating SSSS from TEN, wherein the separation occurs at the dermo-epidermal junction (subepidermal separation).
Malassezia furfur is a fungus that lives on the superficial layers of the dermis.It generally exists as a commensal organism forming a natural part of the human skin microbiota, but it can gain pathogenic capabilities when morphing from a yeast to a hyphal form during its life cycle, through unknown molecular changes.

Erythrasma is a superficial skin infection that causes brown, scaly skin patches. It is caused by Corynebacterium minutissimum bacteria, a normal part of skin flora (the microorganisms that are normally present on the skin). There are two types of erythrasma: generalized and interdigital. Interdigital is the most common bacterial infection of ...
