Tumour Seeding Following Core Biopsy of a Mucoepidermoid Carcinoma of the Parotid: Radiological Evidence and a Surgical Approach to En-Bloc Dissection of the Mass and Tract.

Tumour seeding along the needle tract following core needle biopsy of the parotid is a recognised complication. We present a unique case of mucoepidermoid carcinoma of the parotid in an 18-year-old patient with associated tumour seeding within the core needle biopsy tract. Tumour seeding was confirmed both histologically and radiologically on magnetic resonance imaging as early as 35 days post-biopsy.

Submucosal Intraglossal Fish Bone Extraction: A Case for the Multidisciplinary Team.

Most impacted fish bones in the aerodigestive tract are easily removed or managed in the emergency department. Occasionally, they present as a diagnostic and surgical challenge. We present a case of a submucosal intraglossal fish bone extraction in a 38-year-old male who presented with localized pain in his tongue.

Loss of clusterin shifts amyloid deposition to the cerebrovasculature via disruption of perivascular drainage pathways.

Alzheimer's disease (AD) is characterized by amyloid-β (Aβ) peptide deposition in brain parenchyma as plaques and in cerebral blood vessels as cerebral amyloid angiopathy (CAA). CAA deposition leads to several clinical complications, including intracerebral hemorrhage. The underlying molecular mechanisms that regulate plaque and CAA deposition in the vast majority of sporadic AD patients remain unclear.
