RESUMO
A two- year old Yemeni boy was referred to the Oral and Maxillofacial Clinic of the Aden University because his father had noticed a white lesion on the palate three days before; the child was examined by many dentists and a pediatrician prescribing medical treatment without improvement of the lesion. Questions to the father had not provided any interesting data about previous traumatism, ingestion of caustic substance or history of general disease. A rigorous oral and maxillofacial examination showed a white smooth lesion around 1.5 cm on the middle of the hard palate. According to previous experiences, the final diagnosis was a foreign body adhered to mucosa of the hard palate, the internal cover of a cap from drug bottle, which was removed by the use of a dental probe and college tweezers, leaving a concavity in the involved area that was healed without problems after a few days
