Ocular metastasis as first presentation of renal cell carcinoma: report of 2 cases

Abstract

Authors report the cases of 2 patients who had an ocular lesion as the first sign leading to diagnosis of renal cell carcinoma, an uncommon presentation of this neoplasm. The first patient was a 59-year-old man presented with a mass in the right eye. The histological and immunohistochemical profile of the biopsy showed a probable renal cell carcinoma. A CT scan showed a solid mass in the left kidney. The patient underwent radical nephrectomy and excision of the ocular lesion and had an uneventful evolution. The second patient was a 72-year-old man presenting with an ulcerated lesion on the right inferior tarsal conjunctiva. An excisional biopsy of the lesion showed histological and immunohistochemical patterns of a clear cell carcinoma. Abdominal tomography disclosed a right peripheral renal tumor. A right radical nephrectomy was performed. Renal cell carcinoma may present atypically with metastases to quite uncommon organs. Nephrectomy may be of value in selected cases; the ocular metastases are usually excised for aesthetic and functional reasons.
