Pyoderma gangrenosum. There are two main types of pyoderma gangrenosum: [1] the 'typical' ulcerative form, which occurs in the legs; an 'atypical' form that is more superficial and occurs in the hands and other parts of the body; Other variations are: [4] Peristomal pyoderma gangrenosum comprises 15% of all cases of pyoderma; Bullous pyoderma ...
Pyoderma gangrenosum is variably expressed, which means that it is not always present in all individuals with the disease. It presents as poorly healing ulcers with undermined edges. Pathergy is an important feature (this term refers to the tendency of ulcers to arise at points of injury).
Pyoderma means any skin disease that is pyogenic (has pus). These include superficial bacterial infections such as impetigo , impetigo contagiosa , ecthyma , folliculitis , Bockhart's impetigo , furuncle , carbuncle , tropical ulcer , etc. [ 1 ] [ 2 ] Autoimmune conditions include pyoderma gangrenosum .
Erythema nodosum-like skin lesions can affect the legs. When a skin biopsy is examined under the microscope, there can be signs of a neutrophilic dermatosis . The joint pains in BADAS are typically episodic, migratory and affecting multiple joints.
Martorell's ulcer, also known as hypertensive leg ulcer or necrotic angiodermatitis, [1] is a painful ulceration of the lower leg associated with diastolic [citation needed] arterial hypertension. It was first identified by the Spanish cardiologist Fernando Martorell in 1945, [ 3 ] [ 4 ] who referred to the ulcers as 'hypertensive ischaemic ...
The inflammation and ulceration that occurs as a result of pathergy in pyoderma gangrenosum often responds to systemic steroid therapy. The pathergy reaction is a unique feature of Behçet's disease and, according to the International Study Group for Behcet's Disease, is among the major criteria required for the diagnosis.
In superficial granulomatous pyoderma, ulcers typically have a clean base and vegetating borders, making them more superficial. Unlike pyoderma gangrenosum, superficial granulomatous pyoderma is more frequently associated with truncal involvement and is not always linked to underlying systemic disease.
Venous leg ulcers due to impaired circulation or a blood flow disorder are more common in the elderly. Rare causes of skin ulcers include pyoderma gangraenosum, lesions caused by Crohn's disease or ulcerative colitis, granulomatosis with polyangiitis, morbus Behçet and infections that are usually seen in those who are immunocompromised, for ...
