Choroid Metastasis from Testicular Carcinoma: A Rare Entity.

The aim of this report is to contribute to the clinical understanding of choroid metastasis from testicular carcinoma. A young male patient presented with loss of vision in his left eye with ptosis and proptosis. Fundoscopy revealed bullous retinal detachment with dark hazy vitreous. The preliminary diagnosis of choroid carcinoma with vitreous involvement was made by an ophthalmologist. Later in the physical examination, there was a firm painless left testicular swelling. Testicular tumor markers were raised. Based on ultrasonography, MRI and PET-CT, a clinical diagnosis of left testicular carcinoma metastasizing to the left choroid and vitreous was made. A mixed germ cell tumor was reported on histopathological examination. After cisplatin-based chemotherapy, serum tumor markers normalized and vision improved. Exceptional choroidal and vitreous metastases with absence of other visceral and bony involvement constituted the presenting sign. Although rare, testicular carcinoma must be considered to metastasize to the eye, especially if loss of vision is the chief complaint.
