Abstract

Introduction: Primary immunodeficiency diseases (PIDs), a rare group of gene defects with different manifestations, are at great risk of malignancy. The incidence of diffuse large B-cell lymphoma in the sinusoidal tract is quite rare with nasal congestion, stuffiness, and pain in maxillary sinusmanifestation. Human serine-threonine kinase 4 (STK4) deficiency affects the immune systemwith recurrent bacterial and viral infections, mucocutaneous candidiasis, cutaneous warts, skin abscesses, T- and B-cell lymphopenia, and neutropenia. Patient concern: In this study we describe the infrequent incidence and successful treatment of sinusoidal diffuse large B-cell lymphoma in a STK4 deficient patient with clinical manifestation of severe intractable headaches, unilateral swelling of her face, nasal congestion, stuffiness, and pain in maxillary. Diagnosis: Clinical data including headaches, unilateral swelling of face, nasal congestion, stuffiness and pain in maxillary sinus with confirmed histopathology and magnetic resonance imaging finding confirmed sinusoidal diffuse large B cell lymphoma in a STK4 deficient patient. Intervention: Six cycles of R-CHOP (rituximab with cyclophosphamide, doxorubicin, vincristine, and prednisolone) were administered and after each cycle, G-CSF support was used. Chemotherapeutic drugs were administered with standard dose and no dose reduction was done during the treatment. IVIG treatment continued during the courses of chemotherapy. Outcome: The index patient achieved complete response at the end of chemotherapy courses and was in remission for about 8 months afterward, prior to the date of the present report. Conclusion: PID patient are often at increased risk of malignancies. Sinusoidal diffuse large B-cell lymphoma is quite rare and prognosis isvariable. Early attention to patient'smanifestation, suitable treatment, andmonitoring manifestations caused by PID are critical.
