Eosinophilic cellulitis is a rare skin disorder may be idiopathic or be associated with other conditions. We present a 42- year- old female patient with bilateral atypical cellulitis – like lesions on her arms. The patient had a documented infection with Leptospira recently, and had a positive history for fascioliasis two years before.
Histopathology examination of the lesion was compatible with the acute phase of the Wells' syndrome. We review the related diseases of this syndrome and discuss the possible associations in this patient.
