It presents as a round or oval lesion , 1 cm to 15 cm in diameter, with a halo of erythema . A necrotic center is usually present with a surrounding erythematous edge, representing where the organism invaded blood vessel s and caused infarction s. These ulceritic lesions are single or multiple and heal with scar formation. The mechanism of tissue destruction is Pseudomonas exotoxin A, a toxin similar to Corynebacterium diphtheriae toxin that causes inactivation of elongation factor 2, although sepsis resulting from other gram negative bacteria can also cause this condition.

Pathergy can also lead to ulcerations at the site of surgical incisions. Doctors looking toward a diagnosis of Beh et s disease may attempt to induce a pathergy reaction with a test known as a Skin Prick Test . ref name jimmunol.org http www.jimmunol.org content 177 9 6415.full.pdf ref The inflammation and ulceration that occurs as a result of pathergy in pyodermagangrenosum often responds to systemic steroid therapy. The pathergy reaction is a unique feature of Beh et s disease BD and, according to the International Study Group ISG , is among the major criteria required for the diagnosis. Different positive pathergy reaction rates in BD have been reported worldwide. When BD positive groups are studied for pathergy reaction, the pathergy positive and pathergy negative BD groups showed a similar male female ratio, age at disease onset, and mean disease duration. They also exhibited similar HLA B5 levels and a similar frequency of oral ulcerations in close family members. The mucocutaneous manifestations, systemic disease expression, and severity score were similar in patients with and without the pathergy reaction. The presence of a positive pathergy reaction is not associated with an increased risk for specific mucocutaneous or systemic manifestations of the disease, and probably does not predict a more severe disease course. ref cite journal pmid 10728447 ref It is also important to note that, while a positive pathergy reaction helps to confirm a specific Beh et s disease diagnosis, a negative reaction does not invalidate a BD ... more details
