Locally advanced nasopharyngeal follicular dendritic cell sarcoma misdiagnosed as meningioma.

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
Follicular dendritic cell sarcoma (FDCS) is a rare malignancy, often challenging to diagnose due to its nonspecific presentation and resemblance to other neoplasms. This case highlights a locally advanced nasopharyngeal FDCS initially misdiagnosed as a meningioma, underscoring the importance of differential diagnosis in unusual tumor presentations. A 77-year-old patient presented with nasal obstruction for 3 months. Imaging studies revealed a mass in the nasopharynx prolapsing into the oropharynx, leading to an initial diagnosis of meningioma based on its radiologic appearance. Surgical resection was performed, and histopathological examination, supplemented by immunohistochmical staining, revealed features consistent with follicular dendritic cell sarcoma. The tumor was locally advanced, involving surrounding structures, which complicated the initial clinical and radiologic assessment.
