We examined clinicopathologic findings in 17 cases of peripheral T-cell lymphoma, follicular variant (f-PTCL), and compared these findings with angioimmunoblastic T-cell lymphoma (AITL) to determine whether they were identical to the spectrum of changes seen in AITL and how each of the findings in f-PTCL were related to the characteristics of AITL. Almost all f-PTCL cases showed pathologic characteristics of AITL and immunohistochemical positivities in lymphoma cells for CD4, CD10, Bcl-6, PD-1, and CXCL13. Except for pathologic characteristics, clinicopathologic findings in f-PTCL had few significant differences from AITL. The positive rate for Bcl-6 expression in neoplastic cells was significantly associated with the frequency of polymorphic infiltrates, vascular proliferation, B-immunoblasts, clear cells, Epstein-Barr virus-positive lymphocytes, hepatosplenomegaly, and skin rash. Our study confirmed the continuity between f-PTCL and AITL. Moreover, Bcl-6 expression in f-PTCL was statistically associated with the characteristics of AITL.

A 91 year old patient presented with constipation, abdominal distension, weakness and anorexia lasting for two days. Computed tomography revealed multiple peritoneal masses with significant growth within days and local invasiveness without regard to anatomical boundaries. No lymphadenopathy or hepatosplenomegaly were found. Abdominal paracentesis showed 60,000 cells/mm3 presumed to be neutrophils. During follow-up, there were no clinical or radiographic signs of peritonitis. Trans-abdominal true-cut biopsy from the peritoneal masses was consistent with diffuse large B cell lymphoma germinal center B cell type, clinically presenting as peritoneal lymphomatosis. FISH cytogenetic study identified single BLC-6 gene in the tumor infiltrating lymphocytes. We speculated that this aberration in the patient's immune system cells contributed to this rare, unusual and aggressive lymphoma presentation in an otherwise non-immune compromised patient.
