Sarcomatoid Mesothelioma Revealed After Treatment for Tuberculous Pleurisy: A Case Report.
Article in Respirology case reports, 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
Differentiating tuberculous (TB) pleurisy from malignant pleural mesothelioma is challenging due to similar clinical presentations. We report an 83-year-old man with sarcomatoid mesothelioma initially treated for TB pleurisy. He presented with lymphocyte-predominant exudative pleural effusion and a positive Interferon-Gamma Release Assay. Thoracoscopy revealed purulent effusion, but biopsies were non-diagnostic. Despite empiric anti-tuberculosis therapy, the effusion persisted. A subsequent surgical biopsy showed fibrosis and scattered spindle cells. However, 2 months later, a rapidly growing chest wall mass with bone invasion appeared. A CT-guided percutaneous biopsy showed proliferation of atypical spindle cells and fluorescence in situ hybridization (FISH) analysis allowed for the diagnosis of sarcomatoid mesothelioma. This case highlights the aggressive nature of sarcomatoid mesothelioma and its diagnostic difficulty. For treatment-refractory pleurisy, clinicians must maintain high suspicion, ensuring vigilant follow-up and prompt repeat biopsies despite negative initial results, while consulting pathologists to consider additional FISH testing.
