Introduction:
Recently the application of Kampo, or Japanese traditional medicine, to lymphatic malformation (LM) has been reported, but there are no reports of its effects against neonatal LM. We herein report a case of a neonatal huge cervical LM successfully treated with eppikajutsuto and ogikenchuto without tracheostomy or sclerotherapy.
Patient concerns:
A baby boy with a huge cyst in his right neck was delivered by Caesarean section without a prenatal diagnosis. The cyst extended and slightly compressed the trachea on the 7th day after birth.
Diagnosis:
The patient was diagnosed with LM by ultrasonography.
Interventions:
Although we planned sclerotherapy with OK-432 followed by tracheostomy, his parents refused tracheostomy. Therefore, we started the administration of eppikajutsuto (0.5 g/kg/d) on the 26th day of life instead of sclerotherapy. As the cyst was slightly enlarged at the beginning of eppikajutsuto administration, we increased the dose of eppikajutsuto to 0.75 g/kg/d and added ogikenchuto (0.4 g/kg/d), expecting greater regression of the lesion than with the initial regimen.
Outcomes:
After a few days, the cyst started to diminish in size. Six months later, magnetic resonance imaging showed remarkable regression of the LM without tracheal compression.
Lessons:
The combination of eppikajutsuto and ogikenchuto was thus found to be effective in the treatment of a neonatal LM. This is the first report to demonstrate that the dose-escalation of eppikajutsuto may therefore be effective without any severe adverse effects, even in neonates.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
