Eccrine spiradenoma: analysis of the clinical and pathological features of 7 patients.

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
The purpose of this study was to explore the clinical, pathological, and immunohistochemical features of spiradenoma. The clinical and pathological data of seven patients were analyzed. The analysis revealed that the median age of onset was 34 years, with three patients presenting lesions on the extremities. Clinically, the lesions were mostly skin-colored or red subcutaneous nodules or masses, some of which were tender. Histopathological features included well-demarcated tumor masses composed of two types of cells: small cells with round, deeply stained nuclei and larger cells with lightly stained nuclei, accompanied by ductal differentiation and focal adenoid cystic structures. Lymphomonocytic infiltration was observed in the stroma. Immunohistochemical staining revealed positive expression of cytokeratin (CK) and cluster of differentiation 117 (CD117) in luminal cells and tumor protein p63 (p63) and smooth muscle actin (SMA) in outer myoepithelial cells. SRY-related HMG-box 10 (Sox10) expression was typically diffuse positive. Spiradenoma is a sweat gland tumor for which clinical specificity is lacking, but these nodules have distinct histopathological features. In most cases, a definitive diagnosis can be made with the aid of immunohistochemistry.
