Lymphoproliferative Disease of the Orbit.

Lymphoproliferative diseases of the orbit account for majority of orbital tumors. The pathologies range from reactive lymphoid hyperplasia to specific IgG4-related inflammation to malignant lymphomas. This review summarizes current concepts regarding pathology, clinical presentation, diagnosis, staging, and treatment strategies of major orbital lymphoproliferative diseases based on updated and relevant bibliography.

Safety and efficacy of adjunctive intranasal mitomycin C and triamcinolone in endonasal endoscopic dacryocystorhinostomy.

One of the common causes of failure in dacryocystorhinostomy for nasolacrimal duct obstruction (NLDO) is mucosal scarring and fibrosis around the ostium. Steroid and mitomycin C (MMC) can potentially reduce scarring by their action on the inflammatory and proliferative phase of wound healing, respectively. The purpose of this study is to evaluate the safety and efficacy of combined usage of adjunctive MMC and intranasal triamcinolone (TA) in endonasal endoscopic dacryocystorhinostomy (EE-DCR).
