Postoperative pathergic pyoderma gangrenosum after aortic aneurysm repair

Necrotic ulcerations after splenectomy

“…In summary, PG is a neutrophilic dermatosis often associated with systemic diseases. Pathergy is an important phenomenon demonstrated by trauma‐induced cutaneous lesions of PG and can occur at incisional sites in the postoperative setting . The present report describes a patient with myelofibrosis, a condition infrequently associated with PG, with pathergy at the site of splenectomy, and an excellent response to systemic immunomodulatory and anti‐inflammatory therapy.…”

Pyoderma gangrenosum after aortic aneurysm repair: an umpteenth example of immunocompromised district

“…From a dermatologic point of view, a pathergic response may be likened to the Koebner phenomenon, which refers to the appearance of a new lesion of a pre‐existing skin disorder at the site of an injury of any kind . In conclusion, in the case reported by Leventhal et al ., the new occurrence of PG at a traumatized site cannot be considered a pathergic phenomenon but instead represents a typical umpteenth example of an ICD because the patient was not affected by PG before surgery.…”

“…We read with great interest a recent paper by Leventhal et al ., published in the November issue of the International Journal of Dermatology . In their work, the authors reported a 72‐year‐old man who developed pyoderma gangrenosum (PG) at the site of surgical incision soon after an aortic aneurysm repair.…”

“…We read with great interest a recent paper by Leventhal et al ., published in the November issue of the International Journal of Dermatology . In their work, the authors reported a 72‐year‐old man who developed pyoderma gangrenosum (PG) at the site of surgical incision soon after an aortic aneurysm repair. In describing a possible pathogenic explanation of this rare event, the authors referred to pathergic PG, an uncommon variant of PG that develops in traumatized areas.…”

“…Moreover, we think the adjective “pathergic” is unsuitable for a newly occurring PG that appears on a surgical scar, such as in the case described by Leventhal et al . In fact, the term “pathergy” is used to describe hyper‐reactivity of the skin that occurs as a consequence of minimal trauma and is also used to indicate a particular reaction to needle insertion in Behçet's disease and in PG .…”
