Recurrent Retinoblastoma With Mandibular Metastasis: A Case Report.

Retinoblastoma (RB) is an aggressive intraocular tumor arising from cells of the retina. Infrequently, distant metastasis occurs in advanced stages of the disease. This case report describes the metastasis of the tumor to the mandible, an extremely rare phenomenon. This condition was observed for a recurrent tumor in a patient who initially underwent chemotherapy, making this case report unique and providing new insights into the behavior of this tumor. An overview of the management of a metastatic RB also is discussed.
