Bone in emergency room: Not only a skeletal problem! A rare case of accidental chicken bone ingestion in the afferent loop following Billroth II partial gastrectomy.

We report the case of a 58-year-old male with prior Billroth II gastrectomy who presented with worsening abdominal pain. Contrast-enhanced CT revealed a hyperdense, corticated, triangular-shaped foreign body (FB), consistent with a chicken bone, which had undergone retrograde migration and become impacted in the afferent duodenal loop. The FB's orientation and location were precisely characterized, with associated inflammatory changes but no perforation.

Prevalence of bladder cancer in Costello syndrome: New insights to drive clinical decision-making.

Costello syndrome (CS) is a rare disorder affecting development and growth characterized by cancer predisposition and caused by mutations in HRAS proto-oncogene. Somatic HRAS mutations drive bladder carcinogenesis. The aim of this study was to analyze prevalence and histological characterization of bladder cancer (BC) in a cohort of patients with CS to help clinicians plan effective management strategies.
