Diagnostic dilemma — Unusual case reports from the medical literature

Doctors write case reports to help call rare conditions to the attention of their peers, or to highlight patients whose diagnoses ended up being a bit of a puzzle. Case reports can shed light on emerging trends, hinting at when a condition might be becoming more common. They can also point out treatments that seem to work for diseases that have very few therapeutic options. At Live Science, our writers and editors highlight a report each week to raise awareness of these cases, and in the process, shed light on how the human body works and what happens when things go awry.
