Primary Hepatic Histiocytic Sarcoma Mimicking Hepatocellular Carcinoma.
Article in ACG case reports journal, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Primary hepatic histiocytic sarcoma (HS) is an exceptionally rare malignancy with nonspecific clinical and morphological features that often mimic other high-grade liver tumors making their diagnosis challenging. We report a 74-year-old man presenting with abdominal and back pain, fatigue, and a solitary right-lobe hepatic mass. Imaging suggested hepatocellular carcinoma, and the patient underwent right posterior sectionectomy. Histopathology revealed a high-grade neoplasm of discohesive large cells with eosinophilic cytoplasm and extensive necrosis. Immunohistochemistry confirmed HS. Given the extreme rarity of primary hepatic HS, we provide a focused literature review highlighting diagnostic challenges, immunophenotypic features, and current insights into the molecular landscape of this aggressive neoplasm.
