Sulfasalazine‐Induced Urinary Normetanephrine Elevation Mimicking Recurrent Phaeochromocytoma—A Case Report

Case Reports in Endocrinology, Volume 2026, Issue 1, 2026.
Phaeochromocytomas and paragangliomas (PPGLs) are catecholamine‐secreting neuroendocrine tumours (NETs) of the adrenal medulla and autonomic nervous system. Early recognition and management is critical given their potential morbidity and mortality. For this reason, stand‐alone screening investigations rely on a low diagnostic threshold, achieving high ...

Case Report—An Unusual Presentation of Cervical Meningioma as a Carotid Body Mass Diagnosed by Fine Needle Aspiration Cytology

Cytopathology, Volume 36, Issue 6, Page 606-609, November 2025.
We describe an unusual case of cervical meningioma presenting as a carotid body tumour. This case emphasises the importance of cytoradiologic correlation in lesions with atypical imaging findings; and the crucial role of fine needle aspiration cytology in accurately diagnosing masses in precarious anatomic sites of the head and neck.
