Abstract
We describe a 64-year-old caucasian man with squamous cell carcinoma of the base of the tongue that metastasized to the choroid. The primary tumor was known to be high risk HPV positive and initially diagnosed as T3N3M0 stage IVB two years prior to presentation. Funduscopy revealed an 18 x 17 x 8.9 millimeter mushroom shaped amelanotic tumor with intrinsic vascularity. Ultrasonography revealed medium to high internal reflectivity with echolucent pockets and a positive angle kappa. Marked intrinsic vascularity and associated retinal detachment was also observed. Fine needle aspiration biopsy was performed and 40cGy where delivered via plaque brachytherapy. Histopathologic and cytologic findings of the primary tumor and of the choroidal tumor, respectively are discussed in detail.
