Papillary thyroid cancer in struma testis with malignant transformation in the lung associated with trisomy 17 successfully treated with total thyroidectomy and radioiodine ablation.

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
backgroundStruma testis is a rare entity, and there are only few reports on the malignant transformation of a testicular teratoma to papillary thyroid carcinoma in the literature. In this report, we describe the malignant transformation of struma testis with distant lung metastasis associated with trisomy 17 and a coexisting papillary microcarcinoma in the thyroid. CASE REPORT: A 56-year-old man presented after a left orchiectomy for an undescended left testicle. Pathologic examination identified a monodermal teratoma composed of thyroid parenchyma and associated with a 1.7-cm papillary thyroid carcinoma. Further evaluation showed a pulmonary mass on a chest CT scan. Total thyroidectomy revealed a 0.5-mm focus of papillary thyroid cancer, and removal of the lung mass confirmed metastatic papillary thyroid cancer. Array-comparative genomic hybridization of both tumors showed trisomy 17 in the struma testes and the lung metastasis. The patient responded well to radioactive iodine ablation and has no evidence of cancer 3 years later.
conclusionTo our knowledge, this is the first case of papillary thyroid cancer in struma testes metastatic to the lung. It highlights the difficulties in treating these patients. Surgery to remove cancer foci, followed by radioactive iodine ablation, resulted in an excellent response in our patient. Interestingly, trisomy 17, which has so far been observed only in noninvasive thyroid nodules, was associated with pulmonary metastasis in our patient.
