Mature teratoma presenting as orbital cellulitis in a 5-month-old baby

Orbital teratoma in the foetus: a rare case without proptosis

Background

Congenital orbital teratoma is relatively rare, and few reports of prenatal ultrasound findings in such cases have been published.

Case presentation

A rare case of congenital orbital teratoma at 24 + 2 weeks of gestation was previously diagnosed as microphthalmia, noting how orbital teratoma without proptosis is different from microphthalmia, retinoblastoma and intracranial teratoma. Ultrasound examination, analysis of gross specimens, and histopathological evaluation confirmed the diagnosis of orbital teratoma.

Conclusion

Prenatal ultrasound examination is useful for diagnosis and differential diagnosis of congenital orbital teratoma.

Prenatal Exophthalmia Revealing a Postnatal Orbital Teratoma

Purpose

Teratomas are congenital tumors of stem cells derived from the three germ layers. They are frequently located in the sacrococcygeal region. Orbital teratoma is rare with less than 70 cases reported until 2016. We report the case of prenatal exophthalmia discovered by ultrasound exam which turned out to be a teratoma postnatally. The newborn in our case was female, just as described in the literature. Treatment consisted of total removal of the teratoma and the eyeball. Reconstructive surgery remains a big challenge since our medical technology is limited.

Conclusion

A prenatal exophthalmia on fetal ultrasound should make us think of a teratoma, even if it is very rare. Fetal orbital teratoma may be associated with fetal survival. The infant will benefit from a reconstructive surgery of the orbit.

Orbital immature teratoma: A rare entity with diagnostic challenges

Childhood orbital teratomas are congenital lesions that presents most often at birth with progressive, severe unilateral proptosis. Due to the rarity of such tumors, the diagnosis is often missed with delay in the patient's management. We are presenting a unique case of an immature right orbital teratoma with extensive growth in a full-term newly born baby boy. In this case report, we provide description of the clinical findings, initial misdiagnosis and the eventual management with review of similar reported cases.
