Sarcoidosis in a 53-year-old women followed for a refractory thyroid carcinoma: a misleading association

Thuillier Philippe , Roudaut Nathalie , Kerlan Veronique , Emmanuel Sonnet

Sarcoïdosis is a relatively frequent systemic disease of unknown origin. Prevalence is about 4.7–64 in 100 000. We report the case of a 53-year-old woman followed in our institution since 2007 for a thyroid carcinoma. In 2010, she was diagnosed refractory thyroid carcinoma because of a high thyroglobulin assay (477 μg/l) without uptake on post-therapeutic (131I) whole body scan. Thereafter, the story is marked by the appearance in 2011 of multiple cer...

Polymorphisms of cdkn1b gene may influence hereditary medullary thyroid carcinoma aggressiveness

Barbieri Raquel Bueno , Cunha Lucas Leite , Bufalo Natassia Elena , Villagelin Danilo , Assumpcao Ligia Vera , Maciel Rui Monteiro , Cerutti Janete Maria , Ward Laura Sterian

Despite the importance of the Ret receptor, it is clear that other signal transduction pathways, tyrosine kinase receptors, and tumours suppressor genes are involved in MTC tumorigenesis and progression. Differences in the clinical behaviour of patients harbouring the same Ret mutations may be related to these other genes. Alterations of genes involved in the G1 phase of the cell cycle, including the cyclins, CDKs and CDK inhibitors, are common events in neoplastic development...
