Metastatic renal cell carcinoma in the thyroid gland.

Thyroid incidentalomas on FDG PET/CT are common with one-third of focal uptakes caused by malignancies. Toxic nodules should be excluded. Ultrasound risk-adapted systems can classify thyroid nodules and identify those who need biopsy.

Treatment-resistant severe capecitabine-induced diarrhoea resolved with oral budesonide.

Chemotherapy-induced diarrhoea (CID) is a risk of antineoplastic regimens, often associated with 5-fluorouracil (5-FU), irinotecan and capecitabine. Current treatment guidelines for CID include the use of loperamide and octreotide but do not account for other therapies, including budesonide. Small case reports have shown benefit with budesonide in CID secondary to 5-FU and irinotecan, but there is no literature base addressing budesonide use in CID secondary to capecitabine.
