A Case of Hypereosinophilic Syndrome Presented with Solitary Cutaneous Nodule / 대한피부과학회지

Idiopathic hypereosinophilic syndrome(HES) is a multisystem disease characterized by unexplained prolonged eosinophilia and evidence of specific organ damage, including skin. Cutaneous involvement occurs in more than 50 percent of patients but cutaneous nodule as the only manifestation of HES is rare. We report a case of hypereosinophilic syndrome in a 39-year-old male, who showed a solitary tender coin-sized erythematous nodule on his right lower abdomen for 2.5 months without evidence of systemic involvement.
