Introduction:
Splenic marginal zone lymphoma (SMZL) is rare subtype of malignant lymphoma that is classified as a low-grade B cell lymphoma. Splenectomy is usually chosen for both diagnosis and treatment, which often leads to the resolution of abdominal symptoms and cytopenia.
Case presentation:
We presented the case of a 73-year-old woman who complained of spontaneous perspiration and fatigue. She was referred to our hospital for further treatment of enlarged intraabdominal lymph nodes and splenomegaly. The level of soluble Interleukin-2 receptor was elevated, and malignant lymphoma was suspected. Endoscopic ultrasound fine-needle biopsy of intraabdominal lymph node revealed B cell lymphoma. For a definitive diagnosis, as well as treatment, laparoscopic splenectomy was successfully performed. The histopathological finding was compatible with SMZL. The patient was discharged without any complications and observed to have no recurrence at eight months postoperatively.
Conclusion:
Patients with SMZL is usually expected to have good prognosis with splenectomy. However, careful follow-up is required for aggressive transformation can occur and result in worse prognosis.
