Diffuse large B-cell lymphoma involving multiple immunoprivileged sites presenting as painful ophthalmoplegia: A case report

Abstract

Rationale: Primary diffuse large B-cell lymphoma (DLBCL) is the most common type of non-Hodgkin’s lymphoma. It is very rare to find lymphoma in immune -privileged sitesat the same time. We report a case of rapidly progressing DLBCL involving multiple sites in the central nervous system, testis, and orbit. Patient concerns: A 57-years-old man developed diplopia 1 month ago with severe right periorbital pain and right eyelid ptosis. He developed dysphagia 1 week ago and hoarseness 5 days ago. Diagnoses: The pathology of the left testicle confirmed DLBCL. Immunohistochemical analysis showed that CD20, CD79α, multiple myeloma oncogene-1, BCL2, BCL6 atypical lymphocyte aggregation was positive. Positron emission tomography reveals DLBCL involving the central nervous system, testes, eyes, and other parts of the body. Interventions: We administered glucocorticoids for pre-chemotherapy treatment, but the patient’s condition progressed quickly and was generally poor. The patient’s family decided to discharge automatically. Outcomes: Two weeks after he was discharged, we called for a follow-up visit and were told the patient had died. Lessons: Atypical clinical symptoms of the disease often confuse the doctor’s diagnosis. Adequate examination should be performed before glucocorticoid treatment in order to avoid obscuring the true condition. In some rare diseases, early use of PET-CT may lead to early detection.
