Lacrimal Sac CLL: A Review of Clinical Features, Investigations, and Management.

Abstract

Purpose: This study reviews all reported cases of lacrimal gland chronic lymphocytic leukemia (CLL) to identify patterns in clinical presentation, diagnosis, and management to aid in early recognition and treatment of this uncommon occurrence.

Methods: A comprehensive search of medical literature databases was performed to identify studies reporting lacrimal sac involvement in CLL from 1970 to 2024. Data were extracted regarding demographics, symptoms, diagnostic methods, treatment, and outcomes.

Results: Thirty-three cases of CLL lacrimal sac infiltration were identified. The median age was 71, with a slight female predominance of 54.5%. The most common symptoms were epiphora (63.6%) and pseudo-dacryocystitis or symptoms of dacryocystitis (48.5%). A significant proportion of patients (87.9%) had a known history of CLL at presentation. Chemotherapy combined with surgery was the most frequent treatment, 48.4%, with a positive response in 93.3% of patients. Local recurrence occurred in 10.3% of cases, predominantly in those treated with chemotherapy and surgery, or surgery alone.

Conclusions: Lacrimal sac CLL, though rare, should be considered in patients with nasolacrimal duct obstruction, especially those with a prior CLL diagnosis. Early diagnosis can be aided by imaging and histopathological evaluation, and treatment typically results in favorable outcomes with low recurrence rates. Tailoring treatment based on individual patient factors is essential for optimal management.
