Unilateral progressive proptosis in neonate.
ABSTRACT Orbital teratomas are congenital germ cell tumors that present at birth or within the first few months of life with unilateral proptosis. Primary orbital teratomas produce diffuse enlargement of the orbit. Orbital teratoma contains a wide diversity of tissues ranging from undifferentiated mass of tissue to a fully differentiated fetus in fetus. The tumor components are derived from two or more germinal layers. Most teratomas are cytnlogically benign, having both cystic and solid areas and on occasions may undergo a malignant change. Most patients in the past have been treated by orbital exenteration. We report a case of orbital teratoma that rapidly progressed over a course of days.

ABSTRACT: An unusual case of an orbital teratoma presenting as recurrent orbital cellulitis in a 2-year-old child. Imaging studies demonstrated an extraconal mass with a bony defect and a malformation of the sphenoid. An ectopic tooth was also present. Malformation and defects in the sphenoid have not been previously reported in association with intraorbital teratoma. Attention is drawn to the need for imaging in children presenting with orbital infections in order to exclude an intraorbital mass.Orbit (Amsterdam, Netherlands) 02/2008; 27(4):309-12.

ABSTRACT: Malignant extraconal orbital tumors are very rare during childhood and must be referred as soon as possible to a highly specialized center to be managed by a multidisciplinary team. They are often referred on an emergency basis. Both diagnosis and treatment must be undertaken as soon as possible. The course of these malignant tumors can be acute and can jeopardize the function of the eye or be life-threatening, especially in the event of metastatic locations. Extra-axial proptosis is by far the most frequent revealing symptom. Local and general examinations are of utmost importance. Sometimes diagnosis should be clear with the association of an orbital tumor and deterioration of the general health status favoring metastatic disease. Most metastatic neuroblastomas present such clinical symptoms in young children. Today both CT and MRI are highly valuable in assessing the diagnosis and starting the management of these tumors. Biopsy is mandatory to confirm the diagnosis. It can be reinforced by molecular biology. Among the primitive tumors, soft tissue sarcomas, especially rhabdomyosarcomas, are the most frequent. The diagnosis is suggested when the onset of the disease is acute and the course is rapid. Most respond to neoadjuvant chemotherapy. In the event of a residual tumor, local treatment is indicated so that surgery and/or radiotherapy are used as second-line treatment. Prognosis is closely related to histology. It can be satisfactory (Langerhans’ cell histiocytosis, lymphoma, meningioma, infantile fibrosarcoma) or poor (metastatic tumor, rhabdoid tumor).Neurochirurgie. 01/2010; 56(2):281-286.
UNILATERAL PROGRESSIVE PROPTOSIS IN NEONATE

Key Words :Teratoma, proptosis, exenteration, orbit.
The word "teratoma" means "monstrous growth" in
Greek. Teratomas are rare congenital tumors. They
originate in totipotential cells and are now considered to
be choristomas rather than true neoplasms.
An one month old male child had presented to Nehru
Hospital, Postgraduate Institute for Medial Education and
Research, Chandigarh India, with rapidly progressive
proptosis of right eye since birth. The prenatal period was
uneventful and the baby weighed 3.2 Kg at birth.
Physical examination revealed marked proptosis in the right
eye. The eyeball was embedded within the mass that could
be seen all around the globe. The cornea showed exposure
keratitic changes and was opacified (Fig.I).
The mass had a cystic consistency. Transillumination
was present in the swelling. Ocular mobility was markedly
restricted in all direction, without any vision. The bony
orbit was enlarged. Left eye was normal. Laboratory
studies showed an elevated Serum Alpha Fetoprotein
Radiology showed a large rounded mass occupying the
right orbit with heterogenous attenuation and stippled
calcification. Expansion of the bony orbital wall was seen
without obvious intracranial extension. Various
components of tumor like fat, fluid, and calcifications could
be confirmed. The extraocular muscles and optic nerve
could not be identified (Fig.II).
Presence of frozen globe without any vision prompted us
to do a complete orbital exenteration. The mass was well

encapsulated. The bony orbital wall was expanded. The
Optic foramen and superior orbital fissures were normal.
Gross examination showed a globular, 6 x 5 x 4 cms mass
attached to the posterior surface of the globe. Eyeball was
small and shrunken (Fig. III). Cut section revealed pale
yellow thinly encapsulated tumor that was greasy and soft
in consistency. It had few gray white areas, resembling
tooth with hair shafts, gelatinous, cartilaginous and bony
Microscopy revealed tumor components to be consistent
with a mature teratoma, with derivatives from all three
germinal layers. The tumor was largely lipomatous but
had cystic spaces containing keratin flakes lined by
stratified squamous epithelium and dermal appendages.
Areas with glandular, cartilaginous, bony and neuroglial
differentiation were seen. All components were mature
and there were no dedifferentiated areas. The eyeball was
distorted and free of tumor (Fig. IV).
The first case of orbital teratoma was reported by Holmes1
in 1863. Hoyt and Joe2 had reviewed 30 cases from the
literature. Barber et al3 in 1974 reviewed the literature and
compiled a total of 54 cases.
Congenital orbital teratoma is an extremely rare tumor of
the orbit that may be considered in the diagnosis when a
newborn presents with unilateral proptosis. The other
differential diagnoses must include micro opthalmos with
cyst, congenital cystic eyeball, unilateral congenital
glaucoma, dermoid cyst of the orbit, neuroblastoma,
neurofibroma, nasofrontal or sphenoidal meningocele,
orbital haematoma, hemangioma and lymphangioma. A
diagonosis of primary orbital teratoma was considered
due to the presence of unilateral proptosis, expansion of
the orbit, fluctuation and trans-illumination in the mass.
Rapid growth potential and risk for malignant
transformation4 was the reason for a radical approach in
treatment in the past. Instances of preservation of
proptotic eye, either for possible vision or to act as a
'growing orbital implant' to achieve facial and orbital
symmetry has been seen in the literature.5 Our case had
pronounced proptosis with a frozen globe and absent
vision. Hence, we opted to treat the patient by orbital
exenteration. Prognosis of such tumors is extremely good
at present if preoperative diagnosis is correct.
