Extensive Perianal Basal Cell Carcinoma Presenting With Severe Anorectal Dysfunction.

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
Perianal basal cell carcinoma is an exceedingly rare malignancy that may mimic benign anorectal conditions or anal squamous cell carcinoma. We report an 84-year-old man with a several-year history of a progressively enlarging circumferential perianal lesion, complicated by constipation, chronic fecal incontinence, bleeding, and significant weight loss. Examination revealed a 15 cm ulcerated tumor involving the entire anal verge, with biopsy confirming basal cell carcinoma and sparing of the anal canal mucosa. Imaging showed fecal impaction and perianal soft tissue thickening without metastasis. Given extensive involvement, vismodegib was initiated. This case highlights the importance of early biopsy of atypical perianal lesions.
