Plasmablastic lymphoma of the retroperitoneum in an HIV- and HCV-positive patient: hard to diagnose and harder to treat.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Plasmablastic lymphoma (PBL) is an aggressive diffuse large B-cell lymphoma (DLBCL) with plasmablastic features that was initially described in the oral cavity of HIV-infected individuals. PBL remains a diagnostic challenge given its close morphologic resemblance and overlapping immunophenotypic patterns to other B-cell lymphoid malignancies and plasmablastic plasma cell myeloma (PCM) with extramedullary involvement. The presence of serum monoclonal protein and radiographic evidence of lytic bone lesions favors the diagnosis of plasma cell myeloma over PBL. Distinguishing PBL from PCM is important as PBL is treated with a completely different chemotherapy regimen compared to PCM. PBL carries a guarded prognostic profile among DLBCLs with high relapse rate and poor median survival. We present a case of a 44-year-old HIV-positive man who presented with a large retroperitoneal mass associated with obstructive uropathy, sacral radiculopathy, and inferior vena caval compression. The mass was initially mistaken to be a PCM on histopathology; however, subsequent investigations revealed an extra-oral PBL with plasmacytic differentiation. To our knowledge, this will be the first case of PBL of the retroperitoneum in an HIV- and HCV-positive patient and the second one at this location in the English-language literature. In this report, key differentiating points between PBL versus PCM and newer therapeutic agents such as proteasome inhibitors have been discussed along with related review of literature.
