From lung to breast: a rare case of metastatic lung adenocarcinoma presenting as a breast lump in a male patient.
Article in Journal of surgical case reports, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. An erratum has been issued. Cited by 1 paper.
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
Pulmonary adenocarcinoma, the most common subtype of non-small cell lung cancer, frequently metastasizes to the brain, liver, bones, and adrenal glands. However, breast metastases are exceedingly rare, accounting for 0.2%-1.3% of extramammary metastases, with only 0.1% of secondary breast malignancies originating from the lung. This case report presents a 56-year-old non-smoking male who presented with a unilateral retro-areolar breast lump. Further evaluation revealed ipsilateral axillary lymphadenopathy, and diagnostic biopsy and immunohistochemistry confirmed the lung origin of the breast lesion. This study emphasizes the significance of taking into account breast metastasis in the differential diagnosis of breast lesions in male patients, particularly those with a known primary malignancy. It highlights the need to recognize breast lumps as a potential presentation of secondary breast malignancy.
