BackgroundCirculating tumour cells (CTCs) are increasingly being used in the surveillance of cancer, allowing for potential early detection and real-time monitoring of disease progression. The presence of CTCs in patients with metastatic cutaneous head and neck squamous cell carcinoma (cHNSCC) has not been evaluated.ResultsCTCs were detected in eight of ten patients with regional metastatic cHNSCC (80%; range 1–44 cells/9 mL blood). CTMs were detected in three of ten patients (30%, range 1–4 cells/9 mL blood).MethodsPreoperative blood samples from ten patients with nodal metastases from cutaneous squamous cell carcinomas (cSCC) were analyzed using the IsoFluxTM System for the detection and enumeration of CTCs and circulating tumour microemboli (CTMs).ConclusionsFor the first time CTCs have been detected in patients with nodal metastases from cHNSCC. Further work is required to understand their prognostic significance and potential to directly influence clinical practice.

Stent migration is a well-documented complication following biliary stent insertion. The majority of cases demonstrate passage through the bowel without incident; however, migration may also result in complications, including bowel obstruction or perforation requiring urgent intervention. Risk factors for stent migration comprise of disease pathology as well as stent characteristics including dimension, material and number. Although duodenal diverticulae has been noted as a risk factor for duodenal perforation or obstruction post stent migration, it has yet to be implicated as a contributor to migration itself. Here, we present an unusual case of ileal obstruction secondary to biliary stent impaction, in which the presence of a duodenal diverticulum may be considered a viable risk factor for stent migration.

Chylous ascites (CA) is the uncommon extravasation of triglyceride-rich fluid into the abdominal cavity as a result of the disruption of the abdominal lymphatic system. A patient who had previously undergone a subtotal colectomy presented with a closed-loop small bowel obstruction (SBO), underwent an emergency laparotomy with adhesiolysis and had intra-operative findings of milky intra-abdominal free fluid confirmed on analysis as CA. His post-operative period was complicated by a prolonged ileus, and following resolution, he was subsequently discharged home. Here, we present a case of a closed-loop SBO in which CA may be an indicator of intestinal viability.
