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 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 .
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.
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).
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.
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 example ecthyma gangraenosum.
Another skin condition associated with UC is pyoderma gangrenosum, which presents as deep skin ulcerations. Pyoderma gangrenosum is seen in about 1% of patients with UC and its formation is usually independent of bowel inflammation. [13] Pyoderma gangrenosum is characterized by painful lesions or nodules that become ulcers which progressively ...
Angiolymphoid hyperplasia with eosinophilia (also known as: [1] "Epithelioid hemangioma," "Histiocytoid hemangioma," "Inflammatory angiomatous nodule," "Intravenous atypical vascular proliferation," "Papular angioplasia," "Inflammatory arteriovenous hemangioma," and "Pseudopyogenic granuloma") usually presents with pink to red-brown, dome-shaped, dermal papules or nodules of the head or neck ...
