Papillary Cystadenocarcinoma of the Lacrimal Gland after Radiation for Bilateral Retinoblastoma.

The authors report a case of papillary cystadenocarcinoma of the lacrimal gland after irradiation for bilateral retinoblastoma. A 32-year-old man with a history of bilateral retinoblastoma, diagnosed shortly after birth, was treated with enucleation of the OS and a single session of radiation to the OD. Over 30 years later, he presented with an orbital mass of the right lacrimal gland that on biopsy demonstrated papillary cystadenocarcinoma.
