Recalcitrant course of bullous pemphigoid indicating coexisting hypereosinophilic syndrome: A case report and literature review.

Hypereosinophilic syndrome is a myeloproliferative disorder featuring papules, nodules, urticarial lesions, and blisters. The coexistence of these disorders may highlight the involvement of common molecular and cellular factors. Here, we describe a 16-year-old patient with hypereosinophilic syndrome and bullous pemphigoid.
