It is very uncommon to find dermoid in the floor of the orbit. The case described below merits its reporting due to rarity, confusing clinical features and its successful management.


A 28 years young male presented with a gradually increasing painless swelling at the lower eye lid. The swelling was associated with mild proptosis. On examination the swelling was firm and located between the globe and lower orbital margin and measur­ing about 1.5 cm diameter. The swelling appeared to be not fixed to the bony orbit and skin over it was freely mobile. The direction of proptosis was slightly laterally upward. The vision and fundus picture were normal. Blood DC, T.L.C., ESR stool and urine reports were normal. Intraocular pressure was within nor­mal limit.

X-ray of orbit showed no bony erosion.

Management:- As the case was thought to be due to extension of growth from maxillary antrum, it was decided to have surgical exploration of the orbit in collaboration with E.N.T. surgeon.

An incision about 2.5 cm long was given along the inferior orbital margin through the skin, subcutaneous tissue and septum orbitale and the swelling was explored. Due to accidental puncture of the cyst milky white granular matter came out. It was thought immediately to be a case of tubercular cold abscess. But curiously a few hairs were seen. On exploration more and more hairs came out. So it was thought to he a case of dermoid, his-to-pathology of which confirmed the diagnosis.


As described by Reese dermoid cyst is usually located superficially at the closure of the foetal cleft in upper temporal or upper-nasal position. But in our case it was situated in the floor of the orbit giving the picture of same growth from maxillary antrum. As des­cribed by Hogan & Zimmerman[2] occasio­nally it extends into the bony orbit as during the development of cranial bone. It was suspected to be tubercular cold abscess on exploration. The diagnosis was confirmed on his-to-pathology.


An uncommon presentation of intra. orbital dermoid cyst present at the floor of the orbit is reported, the clinical picture of which was confusing similar to that of extension from maxillary antrum.[4]
