title: Nonsmall cell lung adenocarcinoma metastatic to the vitreous without fundus lesions.
abstract: A 76-year-old man presented with vitritis in the absence of visible fundus lesions. Vitreal cytologic analysis revealed adenocarcinoma; immunostaining was consistent with a pulmonary origin. This case highlights the need to exclude metastasis to the vitreous in a patient with an oncologic history, even in the absence of visible posterior segment lesions. It also illustrates the utility of immunostaining to better determine the tissue of origin when a metastatic lesion is encountered.
