A Case of Primary Urethral Malignant Melanoma With Persistent Bleeding and Severe Anemia.

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: Primary malignant melanomas of the urethra are extremely rare. The initial symptoms typically include hematuria or genital bleeding. This report describes a case of a massive primary urethral malignant melanoma with persistent bleeding. Case Presentation: An 84-year-old woman presented with bleeding and pain from a vulvar mass and severe anemia. She presented with a fist-sized dark-brown multifocal mass extending from the urethra, with persistent bleeding and anemia in the same area. After blood transfusion, tumor resection was performed. Histopathological analysis confirmed the presence of primary malignant urethral melanoma. Conclusion: Urethral malignant melanoma is a rare and aggressive disease that often presents with symptoms that mimic benign conditions. Despite poor prognosis, early surgical resection with adequate margins is crucial. This case highlights the importance of considering malignant melanomas in the differential diagnosis of atypical urethral masses, particularly in patients with persistent bleeding.
