GNAS mutated thyroid carcinoma in a patient with Mc Cune Albright syndrome.

Bone Rep 2020 Dec 18;13:100299. Epub 2020 Jul 18.

INSERM UMR 1033, Université de Lyon, Hospices Civils de Lyon, Hôpital E Herriot, 69437 Lyon, France.

Mc Cune-Albright syndrome (MAS) is a rare disorder defined by the triad of polyostotic fibrous dysplasia, "café au lait" skin hyperpigmentation and hyperfunctioning endocrinopathies, such as precocious puberty. MAS is caused by an activating post zygotic somatic mutation of GNAS gene, coding for the alpha-subunit of the stimulatory G protein (Gsalpha). In endocrine tissues, this mutation results in overproduction of hormones and endocrine cell hyperfunction and proliferation. Read More

Prevalence of hyperfunctioning thyroid nodules among those in need of fine needle aspiration cytology according to ATA 2015, EU-TIRADS, and ACR-TIRADS.

Eur J Nucl Med Mol Imaging 2020 06 9;47(6):1518-1526. Epub 2020 Mar 9.

Department of Nuclear Medicine, University Hospital of Münster, Albert-Schweitzer-Campus 1, 48149, Münster, Germany.

Purpose: Given the large number of patients with thyroid nodules, improvement of the specificity of current ultrasound-based thyroid nodule classification systems (ATA, EU-TIRADS, and ACR-TIRADS) is warranted to reduce the number of diagnostic thyroidectomies. Thyroid scintigraphy has been shown to demonstrate hyperfunctional nodules, associated with a low malignancy risk, in euthyroid patients. However, it is not known if thyroid scintigraphy could improve specificity of current classification systems. Read More

Evaluation of Hot Nodules of Thyroid Gland Using Tc-99m Pertechnetate: a Novel Approach Using Quantitative Single-Photon Emission Computed Tomography/Computed Tomography.

Nucl Med Mol Imaging 2018 Dec 3;52(6):468-472. Epub 2018 Nov 3.

1Department of Nuclear Medicine, Seoul National University Bundang Hospital, Seoul National University College of Medicine, 82, Gumi-ro 173 Beon-gil, Bundang-gu, Seongnam-si, Gyeonggi-do 13620 South Korea.

Planar scintigraphy using Tc-99m pertechnetate is useful for snapshot evaluation of hot thyroid nodules, which are pathologically follicular adenoma and seldom, if ever, malignant. The autonomy of the hot nodules has been demonstrated by the presence of thyroid-stimulating hormone-dependent extra-nodular thyroid tissue besides the hot nodules. Here, we present two cases of hot thyroid nodules in patients who underwent quantitative single-photon emission computed tomography/computed tomography (SPECT/CT). Read More
