Sonographic changes in the thyroid gland after sclerotherapy with doxycycline can be mistaken for thyroid cancer.

Background: The literature considers sclerotherapy to be a safe and effective treatment for benign thyroid cysts. No subsequent diagnostic problems have been reported as a complication. We report the occurrence of focal inflammation after said therapy, mimicking a thyroid malignancy.

ARMC5-negative primary bilateral macronodular adrenal hyperplasia.

A woman in her 60s with chronic fatigue, depressed mood and proximal muscle weakness was referred to our endocrinology department. Physical examination revealed facial plethora, atrophic skin and ankle oedema. Adjuvant blood and urine analyses indicated endogenous ACTH-independent Cushing syndrome.

COVID-19 and Cushing's disease in a patient with ACTH-secreting pituitary carcinoma.

Summary: The pandemic caused by severe acute respiratory syndrome coronavirus 2 is of an unprecedented magnitude and has made it challenging to properly treat patients with urgent or rare endocrine disorders. Little is known about the risk of coronavirus disease 2019 (COVID-19) in patients with rare endocrine malignancies, such as pituitary carcinoma. We describe the case of a 43-year-old patient with adrenocorticotrophic hormone-secreting pituitary carcinoma who developed a severe COVID-19 infection.

Undetectable thyroglobulin makes I whole-body scan and stimulated thyroglobulin obsolete in follow-up care of differentiated thyroid cancer: a retrospective study.

Background: Differentiated thyroid cancer (DTC) is a common malignancy with increasing incidence. Follow-up care for DTC includes thyroglobulin (Tg) measurement and ultrasound (US) of the neck, combined with I remnant ablation when indicated. Diagnostic precision has evolved with the introduction of the new high-sensitive Tg-assays (sensitivity ≤0.
