Bilateral iris metastases from prostate cancer.

摘要

BACKGROUND: Iris metastases of malignant tumors are not common, and most of the cases are unilateral. To our knowledge, there has been no report of bilateral iris tumors metastasized from prostate cancer.CASE: A 71-year-old man with a history of prostate cancer presented with bilateral iris tumors and secondary glaucoma. He had had multiple bone metastases, and had undergone chemotherapy.OBSERVATIONS: Gray-white fleshy tumors spread in the iris of both eyes. Iridocyclitis and secondary glaucoma were present. After external beam radiotherapy, the iris tumors regressed remarkably in volume.CONCLUSIONS: We observed a rare case of bilateral iris tumors, which had probably metastasized from prostate cancer. The tumors were well controlled with conservative therapies including radiation. We believe this article is the first report of bilateral iris tumors metastasized from prostate cancer.
