A hybrid case of eosinophilic folliculitis and eosinophilic cellulitis associated with hypereosinophilic syndrome.

Eosinophilic cellulitis or Wells syndrome encompasses distinct histopathological features but can also be associated with eosinophilic related conditions like hyper eosinophilic syndrome (HES) or eosinophilic granulomatosis with polyangiitis (EGPA) (Churg-Strauss syndrome). We report a case of a Turkish 41-year-old female who presented in clinic with pruritus and tenderness on her chest and breasts, having received several courses of antibiotics for recurrent abscess formation. A year before she had been diagnosed with HES with multiorgan involvement that included biopsy proven eosinophilic folliculitis, and prompted further investigation including bone marrow aspiration that revealed T cell clonality. Biopsy of her rash revealed eosinophilic infiltration of the dermis with flame figures. Ongoing respiratory symptoms and a history of childhood asthma were suggestive of EGPA. This case highlights important associations that should be considered in the investigation of Wells syndrome.
