Lee GI, et al. - Experts assessed the clinical characteristics and treatment outcomes of natural killer/T-cell lymphoma (NKTL) involving the ocular adnexa. This was the largest cohort study on NKTL reported to date and demonstrated that ocular adnexal NKTL was a rare but seriously fatal disease. Acute inflammatory signs characterise it as present in as many as 2-thirds of the patients in this series. In patients presenting with rapidly progressing proptosis and diagnosed promptly for optimal management, it ought to be considered as a differential diagnosis. In both groups, the periorbital swelling was the most common presenting symptom. In 50.0% and 16.7% of cases, respectively, authors noted symptoms mimicking cellulitis and pseudotumor.
