Successful treatment of tongue aspergillosis caused by Aspergillus flavus with liposomal amphotericin B in a child with acute lymphoblastic leukemia

Abstract

A 5-year-old boy with acute lymphoblastic leukemia and probable pulmonary aspergillosis developed a hard, protuberant, white-yellow and aggressive elongated lesion on the left side of his tongue during a febrile agranulocytopenic episode. Despite the use of broad-spectrum antibiotics and other supportive therapies, the lesion increased to about 2 x 4 cm in size within two days and became grey-black with an erythemateous, irregular line. Partial excision of the tongue was performed and isolates recovered from the tongue biopsy specimen were identified as Aspergillus flavus. An increase in the systemic dose (7 mg/kg/day) and local intraoral delivery of liposomal amphotericin B was successful in treating the patient and resulted in improved clinical and laboratory findings. Herein, we document the observation of tongue aspergillosis in a leukemic child with probable pulmonary aspergillosis receiving liposomal amphotericin B therapy and the successful treatment of tongue aspergillosis with an increased dose (7mg/kg) of liposomal amphotericin B. To the best of our knowledge, this is the youngest patient with documented intraoral aspergillosis and only the second case of tongue aspergillosis caused by Aspergillusflavus.
