Pyoderma gangrenosum, Sweet's syndrome, and rheumatoid neutrophilic dermatitis


What's the eponymous name for the uncommon but severe subset of seropositive rheumatoid arthritis patients that develop granulocytopenia, splenomegaly, and therapy resistant leg ulcers?

Felty's syndrome
*The leg ulcers may be secondary to pyoderma gangrenosum or a medium-sized vessel vasculitis
