Abstract
KEY CLINICAL MESSAGE: There is a lack of consensus and evidence on treatment strategies for lacrimal sac carcinomas. Wide en bloc surgical resection with farther prosthetic rehabilitation could be the treatment option in certain cases. ABSTRACT: Malignant epithelial lacrimal sac tumors are rare cancers with high recurrence rates. Diagnosis of these tumors is often delayed as they are confused with chronic dacryocystitis. There is a lack of consensus and evidence on standard treatment strategies for advanced lacrimal sac carcinomas. A case of advanced lacrimal sac squamous cell carcinoma treated with wide en bloc margin-negative surgical resection with further prosthetic rehabilitation without adjuvant therapy and 38 months of recurrence-free postoperative follow-up is presented.
