Sandbank M, Weltfriend S, Wolf R.
A case of dermal vasculitis with arthralgia after intestinal bypass surgery is reported. A 36-year-old woman developed arthralgia and skin rash, 1 year after an ileo-jejunal bypass operation was performed for overweight (130 kg). Skin biopsy showed leucocytoclastic vasculitis in the dermis. E.M. study showed clumps of platelets around small dermis blood vessels, and polymorphous perivascular infiltration. The symptoms subsided after tetracycline treatment.
