Jaundice may be the only clinical manifestation of primary hepatosplenic diffuse large B-cell lymphoma: a case report and literature review

A 64-year old Chinese male patient was admitted to our hospital because of severe jaundice that persisted for 2 months. No swollen lymph nodes or hepatosplenomegaly was detected on physical examination. His laboratory data indicated high levels of direct bilirubin, alkaline phosphatase, aspartate aminotransferase, and alanine aminotransferase. No abnormality was revealed on abdominal computed tomography (CT). However, positron emission tomography (PET)-CT revealed diffuse hypermetabolism in the liver and spleen. Ultimately, liver biopsy guided by PET-CT was performed, revealing that atypical lymphocytes diffusely infiltrated the liver. The immunohistochemical analysis demonstrated that the tumor cells were positive for CD20, Bcl-2, Bcl-6, MUM1, and c-Myc but negative for CD3, CD4, CD8, and CD10. Based on these findings, this patient was diagnosed with primary hepatosplenic diffuse large B-cell lymphoma. After the definite diagnosis, he received chemotherapy and remained in good health as of September 2019.

Assessment of jaundice in the hospitalized patient

Jaundice in the hospitalized patient is not an uncommon consultation for the general gastroenterologist. It is essential to explore the underlying cause of jaundice because management is largely aimed at addressing these causes rather than the jaundice itself. Although the diagnostic evaluation for jaundice can be broad, clinical judgment must be used to prioritize between various laboratory tests and imaging studies. Most importantly, clinicians must understand which conditions are emergent and/or require evaluation for liver transplantation. Further studies need to be performed to better understand the outcomes of hospitalized patients who develop jaundice.
