“…Teratomas ("monstrous tumors") are uncommon neoplasms of unknown etiology composed of heterotopic tissues not akin to the site in which they arise [1][2][3]. It has been hypothesized that they represent remnants of normal embryologic tissue which break off or fail to migrate to their original destination.…”

“…6,17 Others classify them as a type of teratoma in which a single somatic cell layer predominates, and therefore consider them true tumors. 9,18 This report de-scribes concurrent intracranial teratoma and dermoid cyst in a kitten.…”

“…5,7 Teratomas and germcell tumors in general are mostly found in the gonads but sometimes occur in the neck or along the midline of the brain, generally involving the suprasellar, thalamic, or pineal regions. 3,5,9 In veterinary medicine, intracranial germ-cell tumors have been reported mostly in dogs 3,12,13,19 but also in the duck, 4 rat, 16 chicken, 8 horse, 10 and rabbit. 2 The affected animals were generally juveniles or young adults.…”

“…The particular location of some of these cysts at the base of the cerebrum could indicate that they arise from remnants of Rathke's pouch, in a similar mechanism to the theory explaining the formation of teratomas. 9 A failure of surface ectoderm to separate from the neural tube may also be a factor, as a problem in closure of the anterior neuropore could allow ectodermal remnants to be trapped in the frontal lobes. 20 A study on the location and pathogenesis of intracranial dermoid and epidermoid cysts has shown that cysts located close to the hypophysis and possibly associated with Rathke's pouch formation are more likely epidermoid, whereas cysts found in the frontal lobe are mostly dermoid.…”

“…5 Dermoid cysts are considered congenital defects and sometimes as a type of teratoma. 6,9,17,18 Because of their congenital nature, intracranial teratomas and dermoid cysts affect mostly young humans and animals. 2,5,8,16 In dogs, teratomas are mostly diagnosed in young adult to middle-aged animals (3-5 years old).…”

Cervical teratomas are rare tumours which are the result of abnormal prenatal development. They are usually detected at birth, but can occasionally remain silent until adulthood. Obstruction of the airway is the major challenge in the neonatal period. Prenatal diagnosis allows for early consultation with paediatric surgical specialists, so that the time and place of delivery can be addressed, and planning for resuscitative efforts can be organized in advance. If the airway is quickly stabilized and resection of the tumour is not delayed, the prognosis is good. Cervical teratomas in neonates are usually benign; however, malignant transformation and metastasis can occur as a rare event, influencing long‐term survival and prognosis. We present two cases of neonatal cervical teratoma detected prenatally by ultrasound. In one case, termination of the pregnancy was elected. In the other case, the child was delivered at 36 weeks' gestation, an airway was secured, and subtotal resection of the tumour was performed. No developmental or neurological deficit has been detected on long‐term follow‐up at 5 years of age. We present a review of the literature, with attention to outcome and potential for malignancy in neonatal cervical teratomas, in order to provide help in decision‐making, once prenatal diagnosis is made. © 1998 John Wiley & Sons, Ltd.
