Tonsillar lymphangioma with adipose and smooth muscle proliferation: a case report.
Article in Journal of medical case reports, 2026. 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
backgroundLymphangiomatous lesions commonly occur in the head and neck region; however, involvement of the palatine tonsil is rare. Tonsillar lymphangiomatous polyps containing both adipose tissue and smooth muscle proliferation are exceptionally uncommon. We report a rare case of tonsillar lymphangioma with adipose tissue and focal smooth muscle proliferation. CASE PRESENTATION: A 28-year-old Iranian man presented with sore throat and was found to have a pedunculated mass arising from the right palatine tonsil. Physical examination revealed a smooth-surfaced, non-ulcerated polypoid lesion measuring 2 × 1 × 0.3 cm. Owing to the small size and clinically benign appearance of the lesion, no preoperative imaging was performed. Right-sided tonsillectomy was undertaken. Histopathologic examination demonstrated a lymphangiomatous polyp (lymphangioma) composed of dilated lymphatic channels within a fibroadipose stroma with focal smooth muscle proliferation. The lesion was completely excised with negative surgical margins. No recurrence was observed during 1 year of follow-up.
conclusionsTonsillar lymphangiomatous lesions are rare benign entities that may clinically mimic other tonsillar masses. Histopathologic examination is essential for definitive diagnosis. Complete surgical excision appears curative, and recurrence is uncommon.
