Synchronous occurrence of papillary thyroid carcinoma and solitary fibrous tumor of the thyroid: a case report.
Article in Journal of medical case reports, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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
backgroundSolitary fibrous tumors (SFT) are ubiquitous mesenchymal neoplasms of intermediate malignant potential. SFTs of the head and neck are rare, representing less than 0.1% of all SFTs. Solitary fibrous tumors of the thyroid (SFTT) are even rarer. Only 49 cases of SFTTs have been documented in the literature, with just two cases being synchronous with papillary thyroid carcinoma (PTC). By presenting a synchronous PTC and SFTT case, we aim to review the clinical presentation, diagnostic challenges, histopathological characteristics, and management strategies associated with this unusual co-occurrence. CASE PRESENTATION: A 46-year-old North African female patient with no prior medical history presented with a year-long, indwelling cervical swelling. Cervical ultrasound revealed two nodules in the right thyroid lobe and one nodule in the left thyroid lobe. The first right thyroid nodule, measuring 50 mm, is classified as European Thyroid Imaging and Reporting Data System (EU-TIRADS) III. The second right thyroid nodule, measuring 15 mm, and the 25 mm left thyroid nodule were classified as EU-TIRADS IV. A total thyroidectomy with bilateral lymphadenectomy was performed. Microscopic examination revealed that the left nodule and right nodule measuring 15 mm corresponded to invasive PTCs. The second nodule in the right lobe corresponded to a proliferation of spindle cells arranged in sheets and wavy or storiform bundles with a hemangiopericytoma-like vascular pattern. The spindle cells had indistinct boundaries with elongated non-atypical nuclei. There was no mitosis. On immunochemistry, the spindle cells showed strong and diffuse positivity for CD34 and CD99. They are negative for smooth muscle actin, S100, and cytokeratin. It was then confirmed to be an SFTT case. The final diagnosis was of synchronous PTC and SFTT.
conclusionWe presented the third case of synchronous PTC and SFTT. The co-occurrence of these tumors is likely incidental. However, further studies are needed to assess the physiopathology and molecular alterations of this association.
