A Solitary Soft Tissue Mass in the Thigh as the First Manifestation of Occult Lung Squamous Cell Carcinoma: A Case Report.

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
A 69-year-old male patient developed a painless, gradually increasing mass in the upper part of his right thigh, with no pulmonary symptoms. Magnetic resonance imaging revealed a nodular lesion in the lateral femoral muscle, which was initially suspected to be a primary soft tissue tumour. After the mass was surgically removed, the histopathological examination confirmed squamous cell carcinoma (SCC), and the immunohistochemical staining of P63 and CK5/6 was positive. Subsequent FDG PET/CT examination revealed a hypermetabolic nodule in the upper lobe of the right lung. Endobronchial ultrasound-guided biopsy confirmed it as primary lung SCC. This case indicates that isolated skeletal muscle metastasis can be the initial manifestation of occult lung cancer. The research results suggest that seemingly isolated soft tissue masses may be the first sign of latent malignant tumours.
