A lateral neck cyst is a congenital abnormality most commonly occurs in children
and young adults. The development of this pathology caused by disturbances
during the embryogenesis process, during which there is improper closing of the
branchial apertures and incomplete fusion of the branchial arches. This cyst is
typically benign- however, in cases of frequent and recurrent infections various
complications may arise. A lateral neck cyst can be diagnosed incidentally, for
example: during imaging studies to diagnose infection complications. Treatment
first involves curing the infections and potential complications, followed by
surgical treatment to prevent infection recurrence. Here we describe a case of a
patient who presented to the Maxillofacial Surgery Clinic with a sizeable
unilateral neck mass measuring approximately 10 cm in diameter, which had
been growing asymptomatically for almost four years.
