Febrile eosinophilic cellulitis with toxocariasis [20] and infectious cellulitis [41] need to be considered in the differential diagnosis of Wells syndrome (eosinophilic cellulitis), as does bacterial facial cellulitis [42] and arachnid (tick) bites. [43] Distinction from Churg-Strauss syndrome is also required. [30] Wells syndrome may need to be distinguished from bullous cellulitis and should be considered if a patient does not to respond to antibiotics. [34] Cutaneous dirofilariasis may also clinically resemble Wells syndrome. [44]
