This was a real case from Germany. A surgeon accidentally cut his left hand with a scalpel while removing a malignant abdominal tumour called a fibrous histiocytoma. Five months later, a new tumour appeared at the site of the surgeon’s injured hand. Molecular testing confirmed the impossible: the surgeon had developed the same type of tumour as the patient. Histopathological and DNA analyses showed the tumour to be genetically identical to the patient’s original cancer, indicating direct implantation of tumour cells into the wound. The surgeon’s tumour was successfully removed. Two years later, he remained well, with no evidence of recurrence or spread. With sharps injuries, we worry about blood-borne infections. But in exceptionally rare cases, cancer cells can also seed and implant into the wound. 📽️: Zack D Films

The mysterious concoction given to the referee here is probably pickle juice. Pickle juice relieves muscle cramps rapidly, often in under two minutes, not by rehydrating the body or restoring electrolytes, but through a reflex in the throat. The acetic acid in the vinegar triggers sensory receptors that send a signal to the nervous system, forcing overactive, cramping muscles to relax.

*Loosely inspired by real life events* Hospital visits due to ingestion of wire bristles from BBQ cleaning brushes are an under-recognised cause of injury, with approximately 130 hospital visits in the US each year. Most injuries occur when detached wire bristles adhere to grilled food and are inadvertently swallowed. Because the bristles are thin (often 1–2 cm), sharp, and difficult to visualise on plain X-rays, diagnosis may be delayed. Clinical presentations reported in the literature include: 1. Oropharyngeal or tonsillar impaction, leading to throat pain or problems swallowing. 2. Hypopharyngeal or oesophageal penetration. 3. Migration into soft tissues of the neck with abscess formation. 4. GI perforation involving the oesophagus, stomach or small bowel. 5. Migration into the gallbladder has also been reported, caused by a wire fistulation through the stomach. Take home messages: be careful when cleaning the BBQ this summer! Consider this in a patient with unexplained throat pain after a BBQ. 📹: The Good Doctor

Sniffing an alcohol wife can be effective for nausea and vomiting. This acts on olfactory and trigeminal pathways to modulate brainstem nausea centres, resulting in rapid but short-lived relief that may be comparable to ondansetron.

VR You are spot on! Although this was thought to be a traditional serrated adenoma (TSA), the final diagnosis was a pseudopolyp associated with IBD. These can have unusual and sometimes spectacular appearances!
