In December 2009, a report out of Obrezje, Slovenia revealed a lab switching error that resulted in the unnecessary complete stomach removal of a healthy woman, 50-year old Anica Kavecic.  Kavecic had no history of gastric problems, but when a biopsy showed a pervasive cancer in her stomach, she was urged to have an immediate and total gastrectomy. 

The diagnosis stunned both Kavecic and her family physician but the biggest shock came after the surgery when routine post-surgical tests revealed her stomach was cancer-free.  Her biopsy tissue samples had been switched with those of another patient, who in fact did have stomach cancer, resulting in the removal of her perfectly healthy stomach.
