A rare case of hepatoid adenocarcinoma of the lung initially presenting as a painful skin nodule.

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
Hepatoid adenocarcinoma of the lung (HAL) is a rare and aggressive subtype of pulmonary adenocarcinoma, with cutaneous metastasis being an uncommon clinical manifestation. A 49-year-old male presented with a painful, nodular skin lesion on the upper back. Histopathological examination confirmed it as a cutaneous metastasis of HAL. Subsequent imaging revealed a large primary tumor in the left lung and widespread metastatic disease. Remarkably, the skin lesion was the initial and only presenting feature. This case illustrates the variable clinical presentation of HAL and underscores the need for thorough evaluation of atypical skin lesions.
