Incidental Diagnosis of Four Lid Orbital Lymphoma during a Blepharoplasty.

ABSTRACT

Chronic lymphocytic leukemia is characterized by the accumulation of mature CD5-positive B-cells in the lymphoid organs.1 Extranodal involvement occurs in up to 10% of cases and can arise in various tissues, including the orbit. Less than 400 cases of orbital lymphoma are diagnosed per year in the United States, typically manifesting as a form of B-cell non-Hodgkin lymphoma, with extranodal marginal zone B-cell lymphoma being the most common subtype. Orbital lymphoma typically presents with proptosis and a palpable mass; however, patients may also have a relatively benign examination. Here, we present a 76-year-old man with symmetric dermatochalasis and marked fat prolapse of all four lids, who was incidentally diagnosed with secondary orbital lymphoma in all four eyelids during a cosmetic four lid blepharoplasty. His history was significant for RAI Stage 0 chronic lymphocytic leukemia diagnosed 15 years before consultation. Orbital lymphoma presenting as orbital fat prolapse has only been reported a few times in the literature. To our knowledge, this is the first case of secondary orbital lymphoma in all four eyelids found incidentally during an aesthetic four lid blepharoplasty.
