title: Antenatal hemorrhage of a cervical lymphatic malformation presenting as a draining neck mass: An unusual presentation.
abstract: Lymphatic malformations in the neck can present as large fetal neck masses causing airway obstructions with potential perinatal demise and can pose a therapeutic challenge. We present a rare case of prenatally diagnosed large fetal neck mass with features of lymphatic malformation with intralesional hemorrhage of uncertain origin. Postnatal evaluation showed a complex cystic-solid lesion eroding through the skin with an open wound that made it clinically hard to differentiate from a teratoma. Given that malignancy could not be completely ruled out, surgery was favored. Final pathology showed a complex lymphatic malformation with intralesional hemorrhage, despite having no associated capillary, venous or arterial malformations.
