Case Report: Glomeruloid hemangioma in external jugular vein.

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
Introduction: Glomerular hemangioma is a rare vascular tumor characterized by capillary loops that resemble glomeruli within dilated vascular spaces. While primarily reported in the skin and soft tissues, its occurrence in the external jugular vein is extremely unusual. We present a case of a 32-year-old male with a glomeruloid hemangioma located in the left external jugular vein. Case presentation: The patient presented with a small, non-tender, non-pulsatile subcutaneous nodule on the left side of the neck. There were no associated symptoms such as skin redness, swelling, or systemic signs like fever. The patient's medical history was unremarkable, with no hypertension, diabetes, or other significant conditions. Routine laboratory tests, including blood counts, electrolytes, coagulation profile, thyroid hormones, and tumor markers, were all within normal ranges. Imaging studies, including neck computed tomography, chest x-ray, and ultrasound, were performed. Ultrasound revealed a well-defined mass within the left external jugular vein with abundant blood flow and a detectable arterial blood flow spectrum. The patient underwent surgical excision of the mass, followed by histopathological examination. Ultrasound imaging showed a mass measuring 8.6 mm × 5.3 mm within the left external jugular vein, slightly hyperechoic to surrounding muscle tissue, with clear borders and regular shape. Color Doppler imaging detected abundant blood flow, indicating a vascular lesion. Histopathological analysis of the excised mass revealed capillary loops within a dilated vascular lumen, resembling glomerular structures. These findings confirmed the diagnosis of glomeruloid hemangioma. Conclusion: This case highlights a rare presentation of glomeruloid hemangioma in the external jugular vein, emphasizing the importance of considering vascular tumors in the differential diagnosis of subcutaneous neck masses. Surgical resection was successful, and histopathology provided a definitive diagnosis. This case adds to the limited reports of glomeruloid hemangiomas, particularly in atypical locations, expanding the understanding of its clinical manifestations and diagnostic approach.
