A Rare Case of Mucinous Carcinoma Arising in Association with an Intraductal Papilloma.

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
introductionIntraductal papilloma (IDP) is a benign breast lesion that accounts for 3%-6% of core biopsy diagnoses. It is considered a high-risk precursor due to its association with atypia, ductal carcinoma in situ, and invasive carcinoma. Although IDP-NOS (not otherwise specified) rarely progresses to invasive cancer, IDP with atypia carries a higher risk of malignant transformation. CASE PRESENTATION: A 57-year-old woman presented with a mass in the left breast. Mammography revealed a microlobulated mass, and ultrasonography showed a well-defined, coarse isoechoic mass measuring 26 mm with a disrupted anterior border. MRI revealed a high T2 signal outside the center of the tumor, with early enhancement and a plateau phase. Based on these imaging findings, mucinous carcinoma was suspected; a core needle biopsy revealed both mucinous carcinoma and ductal carcinoma with a mucocele-like lesion. The patient subsequently underwent a total mastectomy and sentinel lymph node biopsy for cT2N0 breast cancer. The surgical specimen revealed a mucinous carcinoma spreading around the papilloma, with a distinct transition zone from papilloma to mucinous carcinoma.
conclusionsThis case suggests that mucinous carcinoma may arise from an intraductal papilloma, emphasizing the importance of appropriate clinical follow-up.
