A 14-year-old female with Down syndrome visited our hospital with a fever. During hospitalization, fever persisted, and pancytopenia was observed, so evaluation was performed, hemophagocytic lymphohistiocytosis (HLH) was diagnosed, and chemotherapy began. Three weeks after chemotherapy, ulcerative lesions with white patches on the oral mucosa, gingiva, and lips were observed (Fig. 1). Polymerase-chain-reaction (PCR) test for herpes simplex virus type 1 (HSV-1) on specimens taken from the patient’s oral mucosa and blood have tested positive. In addition, Candida glabrata was identified in the fungal culture of the oral lesion. The chest radiography, lumbar puncture test, and liver biochemical tests were normal. HSV-1 gingivostomatitis with oral candidiasis was diagnosed. The patient was given intravenous, topical acyclovir and oral fluconazole syrup. Two weeks later, oral and lip lesions improved.
