Be careful what you wish for: an ingested foreign body masquerading as cancer.

We present a case in which a patient with suspected colorectal cancer, referred to the surgical outpatient clinic, was subsequently found to have a chicken wishbone apparently perforating the sigmoid colon. This demonstrates the complexities of diagnosis and management of an unusual presentation of ingested foreign body. This case is a useful learning point in consideration of differential diagnosis in the presentation of an apparently malignant lesion.
