Atypical presentation of glomus tumor in the facial superficial vein on high-frequency ultrasound: a case report.

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 are rare mesenchymal tumors that typically occur in the extremities, particularly the intravascular subtype. We present a case report of a 28-year-old male with a painless firm nodule on the left cheek. High-frequency ultrasound (HFUS) revealed a mass within a superficial vein of the left cheek, characterized by well-defined margins, a regular shape, heterogeneous echogenicity, and relatively rich internal vascularity. These ultrasound features were highly similar to the typical imaging of intravascular papillary endothelial hyperplasia, leading to initial misdiagnosis. Following clinical evaluation and per the patient's request for definitive treatment, surgical resection was performed. Histopathological and immunohistochemical analysis confirmed the diagnosis of a glomus tumor originating from a facial superficial vein. In conclusion, this rare superficial venous glomus tumor presented with atypical clinical and imaging features, notably the absence of typical pain and distinct differences from the imaging characteristics of extremity glomus tumors. This case report aims to improve the recognition of such lesions and prevent misdiagnosis between intravascular papillary endothelial hyperplasia and facial superficial venous glomus tumors.
