Giant conjunctival melanoma with rich vascularization causing persistent bleeding.

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
The present study reported a rare case of persistent bleeding caused by conjunctival melanoma containing abundant vascular channels. A 44-year-old Japanese woman presented with a left upper eyelid nodule in February 2023. A pigmented conjunctival mass was present in the upper palpebral conjunctiva. Enhanced computed tomography demonstrated marked enhancement in the left eyelid in the artery phase, indicating hemangioma. The patient suffered blunt trauma to the face in May 2023 and continuous bleeding occurred. Doctors in the emergency room attempted hemostasis by diathermy and suture, but the bleeding could not be stopped. The patient eventually underwent emergent orbital exenteration of the left eye. At high magnification of the histology sample of the bleeding site, small-to-large vascular channels with various vascular lumens made up of endothelial cells within the conjunctival melanoma tissue could be observed. The tumor cells were positive for SOX10, Melan A, S100 and HMB45. We herein propose a novel variant of conjunctival melanoma with rich vascularization, clinically causing persistent bleeding.
