A teratoma is a congenital neoplasm containing structures originating from more than one germinal layer and exhibits a pattern of growth foreign to its anatomic site. The tumour has varied appearances ranging from tissues derived from only two germinal layers to a partially formed foetus. Such teratoid tumours of the orbit are rare and only about 30 cases have been reported in the world literature. The subject of teratoma of the orbit as reported by Hyot & Joe includes a discussion of theories of the genesis and a review of literature. The present case is of interest because of the clarity of its constituent structures specially multiple limbs.

Smt. T.D., 38 years old, para 6+0, gravida 7th was admitted. She expelled a 24 weeks sized foetus within J hour of admission and the placenta was retained. The placenta has to be removed immediately under anaesthesia. Much of the placenta was adherent to the fundus of the uterus and only piecemeal removal was possible. Post-operatively she was given antibiotics, blood transfusion and vitamins. Immunisation against tetanus was done. The foetus was found to have a huge growth from the head, therefore the specimen was taken for study.
(A) C.R. - 25 cm.
Each upper limb - 7.5 cm.
Each lower limb - 7.5 cm.
(B) On section - ovaries and uterus were present (female foetus)
Spleen } normally
Thoracic cage I developed.
All the bones of skull were developed except the two frontal bones which were completely absent. Right Eve - Eye ball was normal. Left Eye - Eye ball was absent. The tumour was found to be arising from the left orbit and there was absence of a demonstrable direct communication between the tumour and the intracranial cavity. It was an irregular mass of variegated consistency having soft gelatious structures, cartilaginous tissues and multiple bony hard projections. The following structures were noted.
(1) (Lt) Accessory foot - 6 cm.
(2) (Rt) Accessory limb bud - 2.5 cm.
(3) (Lt) Accessory hand (ventral)
(4) (Rt) Accessory limb bud
(5) (Lt) Accessory limb (ventral) with well developed bones of lower extremity.
(6) Four vertebral processes scattered in the tumour mass.
(7) (Rt) Accessory hand.
| Discussion|| |
Holmes first described a case of congenital orbital teratoma in 1803. Subsequently about 30 case reports have appeared in the world literature. Almost all the cases presented had a spectacular orbit mass, mostly cystic or polycystic and a few were solid Ahlfeld described a teratoid foetus within a huge orbital cyst. The structures show a benign, but varied histology and ranges from a tumour containing tissues derived only from two germinal layers to a partially formed foetus. In most of the cases the ectodermal and the mesodermal components predominate. The histo-pathologic findings in these orbital tumours are available in 23 cases. Only one case (Holmes, 1863) contained I germinal layer. Three cases, exhibited 2 germinal layers. The remaining cases were found to contain derivatives of all three germinal layers. It is of interest to note that no author has had personal experience with more than a single case. The rarity of occurrence of such a tumour has prompted us to report this case.
