Intrathyroidal Plasmacytoma with Pleomorphic Multilobated Bizarre Cells: A Rare Primary Clinicopathological Presentation Mimicking Anaplastic Carcinoma of Thyroid.

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
backgroundPlasmacytoma involving thyroid gland is infrequent and can present as either primary extramedullary plasmacytoma or secondary to multiple myeloma. METHODS AND
resultsWe present a case of 71 years old male who complained of a huge anterior neck swelling accompanied by dysphagia and dyspnoea. Fine needle aspiration cytology was suggestive of anaplastic carcinoma of thyroid (ATC), however, the subsequent histomorphology supported by immunohistochemistry (IHC) astoundingly favoured the diagnosis of plasmacytoma. Further evaluation revealed the presence of lymphadenopathy and single bone lesion in the present case which was rather suggestive of secondary involvement of thyroid to multiple myeloma. However, the case was unique in view of its presentation as a rapidly enlarging thyroid mass associated with stridor and cytomorphological findings which were of an undifferentiated malignancy favouring ATC. The use of a broad and judicious IHC panel clinched the final diagnosis of plasmacytoma.
conclusionThe present case emphasizes the diligent use of IHC in such cases given different therapeutic and prognostic implications.
