Primary Pulmonary Perivascular Epithelioid Cell Tumour (PEComa): 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
Perivascular epithelioid cell tumour (PEComa) is a rare mesenchymal neoplasm; lung is an exceptional primary site. Herein, we present a surgically resected case of primary pulmonary PEComa and discuss its clinicopathologic features in comparison with previously published cases. A 47-year-old woman presented with a screening-detected right lower lobe nodule. Computed tomography showed a 26-mm S6 lesion abutting the A6. The patient underwent right S6 segmentectomy for diagnosis and treatment. The 30-mm mass was well demarcated and pearly white; histology showed epithelioid cells with sinusoid-like vasculature, rare mitoses and no necrosis. HMB45/Melan-A was positive for focal smooth muscle actin, confirming the diagnosis of PEComa. The patient remained disease free for > 1 year under observation without adjuvant therapy. Although primary pulmonary PEComa is rare and typically indolent, reports of malignant behaviour justify vigilant long-term surveillance and further case accumulation is warranted to refine the diagnostic criteria and management strategies.
