Pleomorphic adenoma of the lacrimal gland in an 18-year-old girl irradiated for bilateral retinoblastoma.
OBJECTIVE
To report a case of pleomorphic adenoma of the lacrimal gland following irradiation for bilateral retinoblastoma.


METHODS
Case report. A 4-month-old girl, with bilateral retinoblastoma, underwent enucleation of the right eye, systemic chemotherapy and bilateral external beam irradiation with a lateral field. The right anophthalmic socket (because of infiltration of the optic nerve) and the left eye (for relapse) were irradiated;. 17 years later, she developed a mass in the superotemporal quadrant of the left orbit. The mass was completely excised.


RESULTS
Pleomorphic adenoma is rare in children and teenagers; it usually presents as a painless, slow growing mass in healthy adults. In this case, it developed as a second primary tumor after irradiation for retinoblastoma.
