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

ABSTRACT: 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.

Project description:IntroductionPrimary breast lymphoma (PBL) is rare, and most cases occur in female patients, with few reported cases in male patients. The clinical presentation is similar to that of breast cancer, but the condition needs to be well understood, as treatment options and clinical course vary. Hence, we provide a relatively rare case of primary breast diffuse large B cell lymphoma (PB-DLBCL) in a male, including its complete clinicopathological features, radiological findings, genomic mutational profiles, and clinical course.Case presentationA 45-year-old male presented with a lump in his right breast for 1 week and was pathologically diagnosed with breast malignancy after a breast puncture biopsy at the local hospital. He came to our hospital for further treatment and underwent breast ultrasound and systemic positron emission tomography/computed tomography (PET/CT) imaging, followed by right mastectomy and sentinel lymph node biopsy. Histomorphology showed diffuse hyperplasia of tumor cells with clear boundaries and surrounding normal breast ducts. The adhesion of tumor cells was poor with obvious atypia. Immunohistochemical results showed that the tumor cells were positive for CD20, Bcl6, and MUM-1 but negative for CK (AE1/AE3), ER, PR, CD3, and CD10. Forty percent of the tumor cells were positive for c-Myc, and 80% of tumor cells were positive for Bcl2. The Ki-67 proliferation index was up to 80%. The tumor cells were negative for MYC and BCL2 rearrangements but positive for BCL6 rearrangement by fluorescent in situ hybridization. No abnormality was found in the pathological examination of bone marrow aspiration. Therefore, the male was diagnosed with PB-DLBCL, nongerminal center (non-GCB) phenotype, dual-expression type. The sample were sequenced by a target panel of 121 genes related to lymphoma. Next-generation sequencing revealed six tumor-specific mutated genes (IGH/BCL6, TNFAIP3, PRDM1, CREBBP, DTX1, and FOXO1). The patient was given six cycles of orelabrutinib plus R-CHOP chemotherapy and two cycles of intrathecal injection of cytarabine. The last follow-up was on April 13, 2023 (17 months). No recurrence or metastasis was found in laboratory and imaging examinations.ConclusionWe reported a relatively rare PB-DLBCL in a male, non-GBC phenotype, dual-expression type. It is worth mentioning that this case had IgH/BCL6 fusion, nonsense mutations in TNFAIP3, frameshift mutations in PRDM1, and missense mutations in CREBBP, DTX1, and FOXO1. To the best of our knowledge, this case is the first report of genomic mutational profiles of PB-DLBCL in males.
