Hypereosinophilic vasculitis: a case report
A 39-year-old patient presented with left hand digital ischemia, preceded by Raynaud phenomenon, and vasculitic rash. For 3 months, he was having digital ischemia affecting the left 2nd and 3rd digits in the form of pallor and gangrenous discoloration with a preceding history of a pinpoint pruritic rash affecting his lower limbs that extended to involve the trunk and upper limbs over a short period of time and responded to only a tapering dose of oral steroids. Examination revealed a delayed capillary refill in all left-hand digits and a weak left radial pulse but no bruit. The rest of his peripheral vascular examination was unremarkable.

Investigations revealed an absolute eosinophilic count of 4.34 K/μL and erythrocyte sedimentation rate of 44 mm/h. A magnetic resonance angiogram showed a beaded appearance of the left ulnar artery distally and the radial artery branches in the left hand and subsequently was diagnosed with hypereosinophilic vasculitis. He was started on oral prednisone of 1 mg/kg daily orally tapering done as well as azathioprine for maintenance.

Two weeks postdischarge, the patient was seen in the outpatient department where his ischemic symptoms improved, and his skin rash healed. Noticed improvement in his splinter hemorrhages was also detected. He continued to do well on 2 years follow-up
