A key to a parent's heart lies in their child's stomach: a case of foreign body ingestion in a child.

Foreign body ingestion is a common problem in pediatrics; some of them can be life-threatening, such as button batteries, magnets, and sharp, pointy objects. Due to the intestine's intrinsic capacity to protect against these events, most foreign bodies pass without harm. Nonetheless, severe complications can arise in some patients. Therefore, prevention, parent education, a high index of suspicion, and close surveillance are essential tools to treat these patients. We present the case of a toddler who accidentally ingested a foreign body (key) and was placed under close surveillance since she was asymptomatic. After 72 hours the key passed and she fully recovered.
