Flame figures associated with eosinophilic dermatosis of hematologic malignancy: is it possible to distinguish the condition from eosinophilic cellulitis in patients with hematoproliferative disease?
Eosinophilic dermatosis of hematologic malignancy is a multifaceted dermatosis with a wide morphological spectrum, presenting as pruritic, erythematous, papular and occasionally vesicular, urticarial, nodular eruptions. Histopathologically eosinophil infiltration in the super and deep dermis was found. We reported a case of eosinophilic dermatosis of hematologic malignancy presented as urticarial and vesicular lesions in a patient with chronic lymphocytic leukemia. A skin biopsy revealed a prominent subepidermal blister and a diffuse infiltrate of eosinophils with flame figures in the dermis and subcutaneous tissue. Although flame figures associated with eosinophilic dermatosis of hematologic malignancy is rarely reported, we believe that it would not seem unusual to find them in this skin disease. Eosinophilic cellulitis, which share clinical and histological features with eosinophilic dermatosis of hematologic malignancy, has also been described as showing an association with hematoproliferative diseases. In order to clearly describe eosinophilic dermatosis in patients with hematologic malignancies, the terminology eosinophilic dermatosis of hematologic malignancy, instead of eosinophilic cellulitis, would be a more suitable term in patients with eosinophilic dermatosis.
