Dermoid and epidermoid cysts masses in the head and neck region of chi
ldren. Although the most common location of inclusion cysts in the hea
d and neck is the bregma, masses in this region must be differentiated
from midline hemangiomas, lipomas, hematomas, or encephaloceles. Incl
usion cysts should be considered in the differential diagnosis of all
midline cystic lesions in infants, because, if left untreated, it may
lead to devastating complications. We present the case of a slowly enl
arging midline mass in a female infant to illustrate the potential for
serious sequelae from inclusion cysts.
