Histopathological changes of lymphatic malformation after bleomycin injection

Alterações histopatológicas da malformação linfática após injeção de bleomicina

ABSTRACT

Lymphatic malformation is a rare orbital tumor that used to be treated surgically, with high complication rates, or recently with intralesional bleomycin injection. We report for the first time the histopathological changes of eyelid lymphatic malformation after water-soluble intralesional bleomycin injection in a 20-year-old woman who had unsuccessful orbital surgical debulking during childhood. The changes confirmed the assumption of fibrosis induced by intralesional bleomycin injection. The minimal bleeding during surgical intervention made it much easier than the usual lymphatic malformation bloody procedure, without postoperative recurrences and with favorable aesthetic outcomes.
