Abscess mimicking pre-cervical and submandibular cystic hygroma in a newborn.

Pre-cervical inflammation is rarely seen in a newborn. Those swellings that are seen are usually congenital, such as vascular malformations, teratoma, dermoid cyst, thyroglossal cyst, cystic hygroma (abnormal lymphatic tissue), and very rarely, inflammation secondary to infection. Being able to differentiate between each condition is important because the course, treatment and prognosis for each condition are different. This case of a neck abscess in a newborn is reported due to its resemblance to cystic hygroma and highlights the similarities between the two conditions.
