BACKGROUND: Diagnosis of @entity6794 can be difficult, leading to overdiagnosis or underdiagnosis. OBJECTIVE: To identify clinical features helpful in establishing a diagnosis of @entity6794 and to compare the characteristics of @entity1 with @entity6794 with those of @entity1 with @entity3179 . METHOD: A retrospective chart review was performed in 28 @entity1 with typical @entity6794 and compared with the clinical features in 28 @entity1 with @entity3179 . RESULTS: (1) Even when other body sites are affected, @entity6794 usually affects the upper and lower legs and feet or peristomal sites compared with @entity3179 that are limited to the lower legs and feet. (2) @entity6794 can be associated with @entity262 , especially @entity29 . (3) Pustules and purulent discharge are features of @entity6794 but not of @entity3179 . (4) Crater-like holes or cribriform scarring is commonly seen in @entity6794 but not in @entity3179 . (5) Pathergy is a specific but not sensitive finding of @entity6794 . It does not occur in @entity1 with @entity3179 . CONCLUSIONS: Diagnosis of @entity6794 should be considered in @entity1 with purulent @entity1066 affecting the legs or peristomal sites. To confirm the diagnosis, specific features should be sought, including pathergy, crater-like holes or cribriform scarring, and association with @entity29 . Other causes of @entity1066 should be excluded.
