Primary anorectal melanoma mimicking polyp in a scleroderma patient: a case report.
Article in Annals of medicine and surgery (2012), 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Primary anorectal melanoma is an extremely rare malignancy of the gastrointestinal tract with a very poor prognosis. Due to the late presentation, most patients with primary anorectal melanoma are diagnosed at advanced stages. Scleroderma is an autoimmune disease characterized by fibrosis of the skin and visceral organs. There is an increased risk of developing cancer in scleroderma patients. Case Presentation: A 57-year-old Syrian female diagnosed with localized scleroderma complained of a sensation of a mass in her anal area. She was diagnosed with primary rectal melanoma and was put on neoadjuvant radiotherapy. Following the radiotherapy, the endoscopy revealed several black lesions in her anal canal, and thus abdominoperineal resection was conducted. Discussion and Conclusion: Malignant melanoma can occur in unsuspected locations such as the anal canal. Novel therapies like anti-CTLA4 drugs have proven efficient in controlling the disease. The lack of data in the literature on this malignancy and the absence of guidelines make it challenging for an optimal approach.
