What is the name of the congenital lymphatic malformation that typically occurs in the cervical region?

The name of the congenital lymphatic malformation that typically occurs in the cervical region is cystic hygroma. This condition is characterized by the presence of fluid-filled sacs that arise from abnormal development of the lymphatic system, leading to a collection of lymph fluid. Cystic hygromas are most often located in the neck area but can occur in other regions as well.

They are predominantly seen in infants and can range in size from small to very large masses. While they may be present at birth, they can also become more prominent during the growth periods of infancy and early childhood.

In contrast, other options like hemangiomas are vascular lesions rather than lymphatic malformations, neurofibromas are nerve tissue tumors often associated with neurofibromatosis, and teratomas are germ cell tumors that usually contain various types of tissues. These distinctions clarify why cystic hygroma is specifically identified as the appropriate answer for this condition associated with congenital lymphatic malformations in the cervical region.
