Bronchial pleomorphic adenoma successfully diagnosed and resected with left lower sleeve lobectomy; a case report and literature review.
Article in Respiratory medicine case reports, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Tracheobronchial tumor is a relatively uncommon type of respiratory tumor. Seromucous gland tumors, such as adenoid cystic carcinoma, mucoepidermoid carcinoma, and pleomorphic adenoma, are a part of this category. Among them, pleomorphic adenoma is especially rare. This report describes a case of bronchial pleomorphic adenoma successfully diagnosed and removed with surgery. A 70-year-old Japanese man presented with abnormal chest shadow and intermittent fever. A subsequently conducted chest computed tomography revealed a 40mm-sized mass in the left lower bronchus and distal obstructive pneumonia. Because a transbronchial biopsy was not diagnostic, a left lower sleeve lobectomy was performed. As a result, the mass was completely resected and a diagnosis of pleomorphic adenoma was made. Treatment options for pleomorphic adenoma include surgery and endoscopic resection, because observation is sometimes inadvisable due to the risk of metastasis or malignant transformation. Furthermore, complete resection is diagnostically appropriate because pleomorphic adenoma is sometimes undiagnosed or misdiagnosed with partially resected or biopsied specimen, due to the heterogeneity in pathology. This case underscores the challenges in diagnosing pleomorphic adenoma and highlights the importance of complete surgical resection for definitive diagnosis and treatment.
