A nipple-like lesion: A case report of leiomyosarcoma on the back.
Article in SAGE open medical case reports, 2026. 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
Leiomyosarcoma (LMS) of the skin is a rare malignant neoplasm that can have varied clinical presentations, even mimicking benign lesions, making diagnosis challenging. We describe a 74-year-old male with a history of subcutaneous LMS of the left leg treated successfully with surgery, chemotherapy, and radiation over 10 years prior, who presented with an incidental papule on the lower back resembling an accessory nipple. Biopsy revealed a spindle cell tumour with diffuse smooth muscle actin and desmin positivity and a high Ki-67 index, consistent with a non-metastatic subcutaneous LMS. Wide local excision confirmed dermal and subcutaneous involvement with negative margins. This case is notable for the occurrence of two distinct primary LMS lesions more than a decade apart, underscoring the importance of long-term surveillance in high-risk patients. Given the potential for recurrence or metastasis, careful histopathologic evaluation and ongoing monitoring remain critical in the management of LMS.
