A Rare Case of Intravascular Papillary Endothelial Hyperplasia of the Hypopharynx: A Case Report and Literature Review.
Article in Cureus, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
Intravascular papillary endothelial hyperplasia (IPEH), also known as Masson's hemangioma, is a rare benign vascular lesion characterized by an unusual pattern of endothelial proliferation within a thrombosed vessel. Histologically, IPEH is defined by prominent intraluminal papillary structures composed of a single layer of enlarged endothelial cells, lacking cytologic atypia, mitotic activity, and necrosis. Here, we report a rare case of IPEH identified in the hypopharynx of a 56-year-old male patient, incidentally, on imaging for evaluation of unrelated upper back pain. We describe the clinical presentation, histopathologic findings, differential diagnosis, and review of the current literature to enhance recognition and management of this entity in rare/unusual sites.
