Lower lip teratoma with ventral capillary malformation in an infant: case report and literature review.
Teratomas are tumors that are derived from two or three of the primordial germ layers: ectoderm, mesoderm and endoderm. They arise most commonly in a midline or paraxial location from the brain to the sacral area and are most often located in the sacrococcygeal region. Head and neck teratomas are rare neoplasms and their incidence is 1 in 20,000-40,000 live births. 90% of head and neck teratomas present during the neonatal and infantile period, predominantly involve the neck and nasopharynx. Teratomas rarely originate from other superficial structures of the head. This paper describes an exceptionally unusual teratoma of the lip concomitant with a ventral capillary malformation.
