Nasolacrimal sac metastasis from colorectal carcinoma: a case report

We report a rare case of metastasis to the nasolacrimal sac from colorectal carcinoma in a 69-year old man. Despite tumor removal and endoscopic dacryocystorhinostomy with stenting, the tumor recurred 3 months later, which was treated with chemotherapy and radiotherapy. Five months later, the patient eventually died from respiratory failure secondary to malignant pleural effusion.
