AI Article Synopsis
- Seeding of CNS cancers to the abdominal cavity via VP shunts is rare, but documented; skin metastasis from GI cancers via a VP shunt is even rarer.
- An 85-year-old man had a nodule over his VP shunt, which was found to be an adenocarcinoma likely from the upper gastrointestinal tract.
- This case highlights the need for biopsies to determine the nature of such nodules for better prognosis and management, weighing the risks of potential shunt infections.
Article Abstract
Seeding of a central nervous system malignancy to the abdominal cavity is an uncommon but well documented complication of a ventriculoperitoneal (VP) shunt. However, the metastasis of a primary gastrointestinal cancer to the skin via a VP shunt is extremely rare. We report the clinical case of an 85-year-old male who presented with a right upper quadrant nodule over his shunt, which on histopathology and tumour marker profile was diagnosed as an adenocarcinoma of likely upper gastrointestinal origin. This case illustrates the importance of proceeding to biopsy to inform prognosis and management, despite the risks of shunt infection.

Primary cutaneous amoebiasis is rare, and typically affects immunocompromised patients and presents with unique clinical and histopathologic changes. Untreated, the infection could progress to involve the central nervous system, which is almost universally fatal. We present a case of primary cutaneous acanthamoebiasis in a patient with chronic lymphocytic leukemia on acalabrutinib.

Primary effusion lymphoma (PEL) is a rare and aggressive B-cell lymphoma typically associated with human herpesvirus 8 (HHV-8) and Epstein-Barr virus infections. It classically presents as a malignant effusion in body cavities, but rarely presents with an extracavitary variant characterized by solid tumors in lymph nodes or extranodal sites such as the gastrointestinal tract, skin, lungs, and nervous system. This case report describes an unusual presentation of primary cutaneous extracavitary PEL in an HIV-positive patient that has only been reported in 8 cases previously.

Background: The limited understanding of factors influencing the disease progression of oral lichen planus (OLP) poses challenges in delivering effective and personalised treatment for this condition, known to increase the risk of oral cancer and adversely impact patient quality of life.
Objective: This study aimed to systematically identify clinical predictors of disease severity in OLP patients.
Methods: This cross-sectional and single-site prospective study was conducted between December 2021 and February 2024 in the Departments of Oral Medicine and Oral & Maxillofacial Surgery, Aberdeen Royal Infirmary.
