Primary Colonic Leiomyosarcoma Initially Diagnosed as Kaposi Sarcoma: A Case Report.
Article in Cureus, 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 colonic leiomyosarcomas are relatively uncommon mesenchymal tumors, often posing diagnostic challenges due to their overlapping features with other gastrointestinal tumors. In this article, we report the case of a 61-year-old male who presented with abdominal pain and weight loss, whose initial endoscopic biopsy was interpreted as colonic Kaposi sarcoma, with tumor-cell positivity for cluster of differentiation 34 and human herpesvirus 8. Further surgical intervention, characterized by a right radical hemicolectomy and histopathological analysis, revealed a primary colonic leiomyosarcoma. This case highlights the diagnostic complexity associated with colonic leiomyosarcomas, the importance of comprehensive histopathological assessment, and the need for timely surgical management. The clinical course of the patient analyzed illustrates how misclassification can alter therapeutic strategies, underscoring the value of a timely and accurate diagnosis in guiding appropriate oncological management.
