About half of those affected by pyoderma gangrenosum have none of the associated risk factors. It is more commonly a complication of ulcerative colitis compared to Crohn disease. IBD-associated pyoderma gangrenosum is associated with clinically mild IBD, erythema nodosum, and female sex. Underlying bowel disease is active in over half of the patients at the time of an episode of pyoderma gangrenosum Pyoderma gangrenosum is most often located on the lower extremity and can be periostomal.

Ulcerative and pustular types of pyoderma gangrenosum may arise. What causes pyoderma gangrenosum? Pyoderma gangrenosum is an autoinflammatory disease excessive response to an internal antigen due to some form of neutrophil dysfunction [1]. T lymphocytes and cytokines are involved. There may be a genetic predisposition. What are the clinical features of pyoderma gangrenosum? Pyoderma gangrenosum usually starts quite suddenly, often at the site of a minor injury. It may start as a small pustule, red bump or blood-blister.

The skin then breaks down resulting in an ulcer. The ulcer can deepen and widen rapidly. Characteristically, the edge of the ulcer is purple and undermined. Pyoderma gangrenosum is usually very painful. Several ulcers may develop at the same time or over months to years.

Untreated, the ulcers may continue to enlarge, persist unchanged or may slowly heal. Treatment is usually successful in arresting the process, but complete healing may take months.

This is particularly true if there is an underlying venous disease, another reason for leg ulcers. Deep ulcers heal with scarring, and this is sometimes with a characteristic cribriform or criss-cross pattern. A rare superficial bullous variant of pyoderma gangrenosum may heal without leaving a scar. Pyoderma gangrenosum.


Ecthyma gangrenosum

Muneeb Shah1; Jonathan S. Introduction Ecthyma gangrenosum EG is a cutaneous infection that most commonly occurs in immunocompromised individuals with fulminant bacteremia. EG was first described in by Canadian pathologist Dr. Lesions appear as gangrenous ulcers with erythematous borders. Perivascular invasion and resultant ischemic necrosis of the associated skin result in the classic macroscopic appearance. Prompt recognition and empiric therapy with broad spectrum antipseudomonal agents are of critical importance.


Ecthyma gangraenosum

Ecthyma Wat is ecthyma? Er bestaat ook een variant van ecthyma die veroorzaakt wordt door de pseudomonas bacterie Pseudomonas aeruginosa. Deze vorm wordt ook wel pseudomonas gangrenosum genoemd en komt vrijwel alleen voor bij mensen met een sterk verlaagde immuniteit. Hoe ziet het eruit? Ecthyma begint als een rode, nattende plek waarin een blaarachtige afwijking in kan ontstaan. De kleur kan diep paars worden.

Then, it develops into a pustule, and then a bulla with central hemorrhagic focus. The bulla progresses into an ulcer which extends laterally. Finally it becomes a gangrenous ulcer with a central black eschar surrounded by an erythematous halo. They are most commonly seen in perineum and under arm pit.
