[A rapidly progressed metastatic choroidal tumor from a hepatocellular carcinoma]

Metastatic choroidal tumor stemming from a hepatocellular carcinoma (HCC) is very rare. We report a case of a metastatic choroidal tumor stemming from a hepatocellular carcinoma.

A 50-year-old man became aware of a visual field defect in his left eye starting 1 month previously. He had undergone surgery for HCC nine years before, and had received radiation therapy for lung and brain metastasis of HCC. Funduscopic examination revealed a red choroidal mass with subretinal bleeding. One month later, light perception of the left eye disappeared with rapid growth of the tumor and high intraocular pressure. Because the ocular pain was uncontrollable, enucleation of the left eyeball was performed. In histopathological examination, the choroidal tumor consisted of tumor cells showing characteristics of HCC such as intracytoplasmic glycogen granules, fatty degeneration, and necrosis of the tumor cells.

The clinical characteristics of metastatic choroidal tumors from an HCC are a red appearance and rapid growth with retinal detachment and subretinal hemorrhage.
