Simultaneous bilateral conjunctival and orbital lymphoma presenting as a conjunctival lesion

A 44-year-old man with the diagnosis of a conjunctival lymphoma in the left eye was also found on further evaluation to have a lymphoma in the opposite orbit. The patient had no systemic signs of the disease, and was treated with localized radiation therapy. Although simultaneous presentation of lymphoma affecting the conjunctiva in one eye and the orbit on the opposite side is rare, any patient with an isolated conjunctival lymphoma should have a careful evaluation of the opposite eye and orbit, including an orbital computed tomographic scan to rule out simultaneous involvement.
