Black Hole in My Child’s Mouth: An Unusual Case of a Foreign Body Mimicking a Palatal Lesion in a Healthy Infant

Foreign bodies in the oral cavity of children can pose significant diagnostic challenges, particularly when they are asymptomatic and mimic serious pathological lesions. We report an unusual and deceptive case involving a 16-month-old infant who presented with what appeared to be a suspicious black lesion firmly adhered to the hard palate. Upon further investigation, the lesion was identified as a plastic emblem dislodged from a car key fob, firmly stuck due to adhesive residue. This case underscores the critical importance of thorough history-taking, detailed and careful oral examination, and the need to consider foreign bodies in the differential diagnosis of oral lesions. Early recognition and appropriate management can prevent unnecessary investigations, avoid misdiagnosis, and reduce caregiver anxiety.
