摘要
BackgroundThe typical manifestations of Penicillium marneffei (nowadays Talaromyces marneffei) infection in children without human immunodeficiency virus (HIV) remain unclear. The current work presents the case of a child without an underlying disease who was infected with P. marneffei comorbid with eosinophilia.Case presentationA 2-year-old male was infected with P. marneffei. A physical examination revealed a high-grade fever, ulcerated lesions in the oral mucosa, anemia, pruritic erythematous papules on the sac and thigh and watery diarrhea. A chest enhanced computed tomography scan showed multiple small, nodular, high-density shadows in the lungs, multiple lymphadenectasis in the hilum of the lungs and mediastinum, and liquid in the right pleural cavity. The patient's plasma was negative for HIV. Routine blood tests initially indicated that the patient had leucopenia; however, later tests indicated that he had leukocytosis. This peak was caused by a significant increase in eosinophils. The total IgE and specific allergen levels were normal. The stool was negative for parasite eggs. Aspergillus antigen (galactomannan, GM) levels were significantly increased and were present in the serum for a relatively long period.ConclusionsEosinophilia can occur during P. marneffei infection, and this finding might provide additional information on the activity of this intracellular parasite. In addition, GM detection might be useful for monitoring the effect of antifungal treatments; however, this theory requires more data for verification.
