Cervical lymph node metastasis from occult tonsillar squamous cell carcinoma with incidental ectopic parathyroid tissue: a case report.
Article in Journal of surgical 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
Parathyroid glands originate from the third and fourth branchial pouches, and alterations in their embryological migration may result in ectopic parathyroid tissue, a rare finding, particularly within cervical lymph nodes. We describe the case of a 74-year-old man presenting with neck swelling, weight loss, dysphagia, and respiratory symptoms. Clinical examination revealed a firm cervical mass, while ultrasound, fine needle aspiration, and computed tomography imaging were inconclusive. Surgical excision and histopathological evaluation revealed metastatic squamous cell carcinoma and incidental ectopic parathyroid tissue within a cervical lymph node. A tonsillar carcinoma was subsequently identified as the primary tumor, and the patient was treated with radio-chemotherapy. This case highlights the rarity of ectopic parathyroid tissue in lymph nodes, especially in the absence of calcium metabolism disorders, and emphasizes the importance of accurate differential diagnosis to avoid misinterpretation and inappropriate management.
