RÉSUMÉ
Intrathyroidal parathyroid adenomas (IPAs) are a rare cause of primary hyperparathyroidism. They are often difficult to localize preoperatively and intraoperatively, making diagnosis and treatment challenging. Current data on IPAs are sparse and fragmented in the literature. This makes it difficult to compare the effectiveness of different imaging and surgical techniques. To address this issue, this scoping review maps the literature on IPAs, focusing on four domains: clinical presentation, current localization methods, different surgical techniques, and histopathological features. A search of MEDLINE, Embase, and the Cochrane Library was conducted, with 19 studies meeting the inclusion criteria. The characteristics of IPAs on ultrasound, fine-needle aspiration, CT, MRI, sestamibi-based techniques, and selective venous sampling are summarized. Emerging imaging modalities, including autofluorescence, are introduced. Surgical methods and intraoperative factors that correlate with high success rates for removal are highlighted. This review also identifies gaps in knowledge to guide further research into this area.

Malignant thyroid teratoma in adults is a rare tumour with less than 40 cases reported worldwide. Our case is of a 29-year-old man who presented with a thyroid lump and compressive symptoms. He underwent multiple investigations before being diagnosed with a malignant thyroid teratoma. There are no established guidelines in the management of this tumour yet. In this case report, we discuss the diagnosis, treatment and follow-up of the patient and reflect on the published literature on this tumour.
