Application of contrast-enhanced ultrasound for extradigital glomus tumor in the thigh: a case report.
Article in Frontiers in oncology, 2025. 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
Glomus tumors (GTs) are rare neoplasms, classically presenting as subungual lesions with pathognomonic triad of severe paroxysmal pain triggered by cold, pressure, or touch. Extradigital glomus tumors (EGTs) pose significant diagnostic challenges due to their anatomical atypicality and frequently ambiguous clinical manifestations. Ultrasonography remains the primary imaging modality for evaluating soft tissue masses. In the diagnostic assessment of GTs by sonographers, the identification predominantly relies on characteristic clinical presentations combined with the demonstration of intratumoral hypervascularity through color Doppler imaging, as grayscale ultrasound features exhibit nonspecific characteristics. However, conventional ultrasonography encounters significant diagnostic challenges in EGTs with atypical clinical presentations and deep-seated locations, primarily due to the markedly reduced sensitivity of color Doppler in assessing blood flow within deep soft tissue lesions. In contrast, contrast-enhanced ultrasound (CEUS) allows dynamic visualization of microvascular perfusion patterns, enabling precise evaluation of intratumoral hemodynamic characteristics. This technique may assist in enhancing diagnostic accuracy and guiding targeted biopsies. We report a case of a 56-year-old man with a 4-year history of drug-resistant left thigh pain. CEUS revealed a 21-mm intramuscular mass exhibiting rapid heterogeneous enhancement followed by rapid washout, suggesting hypervascularity. Histopathology confirmed a glomus tumor of uncertain malignant potential. This case highlights the clinical and imaging characteristics of EGTs, providing clinicians with a comprehensive understanding of this rare entity.
