Wells Syndrome with Generalized Oedema

Wells syndrome or eosinophilic cellulitis is a rare and relapsing skin disease which lacks systemic involvement. A skin biopsy is needed to establish a diagnosis. Several precipitating factors have been proposed but no proven causative link has been found. On the other hand, Churg-Strauss syndrome, also known as eosinophilic granulomatosis with polyangiitis (EGPA), an auto-immune disease, is associated with multiorgan, including cutaneous manifestations. We report a case with overlapping features of Wells and Churg-Strauss syndrome, suggesting that these syndromes could be part of the same nosological entity. LEARNING POINTS: Biopsies are essential to establish a diagnosis in unusual cases of cellulitis. COVID-19 vaccination is a putative trigger for Wells syndrome. There is significant overlap between Wells and Churg-Strauss syndromes.
