A choristoma is a tumorous or cystic proliferation of tissue elements at a site where they normally do not occur. A good number of cases of episcleral osseous choristoma have been described.,,,,Although choristoma in ectopic lacrimal gland tissue has also been described1by Duke Elder, yet we could not find any report describing such a tissue in normal lacrimal gland. In this case report the presence of choristomatous tissue in palpebral part of the lacrimal gland has been described.
| Case Report|| |
A five years old female was reported in the out patient department of M.U. Institute of Ophthalmology with the complaints of swelling in upper outer part of the left eye for the last three years. The swelling was painless, there was sense of heaviness in that area and was increasing very gradually. There was no other complaint. There was no history of trauma.
On examination there was fullness in the upper outer quadrant of the orbit. On everting the lid, a growth projecting down from outer part of upper fornix could be seen [Figure - 1]. It was reddish white in colour, non- friable and measured 11.Ox 10.0mm in size. It was neither fixed to the' lid nor to the eyeball and was covered by conjunctiva. It was slightly tender on deep pressure. The swelling was not continuous into the orbit. On the basis of these findings a clinical diagnosis of inflammatory 'granuloma of palpebral part of the lacrimal gland was made.
The growth was easily removed into by opening the covering conjunctiva. The growth measured 11.0 x 10.0x5mm. The cut surface was grayish white with small areas of light bluish discolouration.
On microscopic examination there were alveoli of lacrimal gland separated by fibroconnective tissue. In between, the presence of cartilage tissue could be seen [Figure - 2],[Figure - 3]. There was no evidence of malignant cyyor any benign neoplasm. Therefore a diagnosis of choristoma of lacrimal gland was made.
| Comments|| |
In a choristoma histologically the new tissue shows normal structure but the site at which they are located is not normal for this. Further, these lesions do not fit into teratoma, which should be composed of multiple tissues.
There may be a cartilage or even a bone in the normal structure of sclera in many fishes, amphibia, reptiles, and birds. However, we could not find any report on the presence of cartilage in the lacrimal gland.
Duke-Elder described that in sturgeons, a type of marine fish, there may be a plaque of bone external to the scleral cartilage. May be in the present case the presence of cartilage in )palpebral part of the lacrimal gland represents an atavistic phenomenon.
| Summary|| |
A case of cartilagenous choristoma of palpebral part of lacrimal gland has been reported.
