title: T-cell-rich B-cell lymphoma presenting as liver disease.
abstract: We describe a series of eight cases of T-cell-rich B-cell lymphoma diagnosed on liver biopsy and collected over a period of 15 years. Of seven cases that were referred from elsewhere, in only one was the correct diagnosis of B-cell lymphoma suggested. Common errors included misdiagnosis as inflammatory disease on histology, and misinterpretation as T-cell lymphoma on immunohistochemistry. However, the cases had a distinct morphological appearance and immunohistochemical profile. They showed a lymphohistiocytic or granulomatous infiltrate, usually centred on portal tracts and containing abundant small T-cells and scanty B-cell blasts. All patients had an atypical clinical presentation which favoured non-neoplastic liver disease. In seven cases liver involvement represented Stage IV disease and in one case disease was confined to the liver consistent with a primary hepatic lymphoma. Despite combination chemotherapy, the prognosis was poor with no patients surviving beyond 15 months from diagnosis. We believe T-cell-rich B-cell lymphoma to be an under-recognized subset of non-Hodgkin's lymphoma that may mimic primary liver disease.
