Intraocular metastasis from an anal squamous cell carcinoma: a case report

This case presents the exceptionally rare phenomenon of intraocular metastasis from a primary anal squamous cell carcinoma. Per our literature review, this is the first reported case of such an occurrence, which adds to the clinical complexity of this case in terms of timely diagnosis, effective treatment modalities and prognosis. In these cases, early recognition and diagnosis is critical, as intraocular metastasis significantly affects quality of life as well as overall prognosis. Therefore, through this case report, we aim to highlight the rare intraocular presentation of metastatic anal cell carcinoma, so that clinicians maintain a broad differential diagnosis when evaluating new ophthalmic symptoms in patients with anal cancer.
