Infants are often difficult to examine, and foreign bodies in the hard palate are misdiagnosed as neoplastic or inflammatory lesions in some cases. We present a rare case of a foreign body that was not diagnosed until its removal from the hard palate of an infant under general anesthesia. A healthy 12-month-old girl with a protruding foreign body on the hard palate was referred for close investigation. A white-yellow protruding foreign body measuring approximately 10 mm was found on the palate. Computed tomography revealed a radiopaque foreign body at the border. It was decided to examine and performed biopsy under general anesthesia, and the foreign body removed easily was an obviously plastic object with a semicircular shape and a brim around it. The histopathological examination of the abnormal gingiva under the foreign body revealed inflammatory granulation tissue. This report highlights the difficulty in diagnosing an infant with a foreign body in the hard palate and the safety of its removal under general anesthesia. Clinicians must consider the possibility of foreign bodies causing lesions on an infant’s hard palate. Therefore, careful examination and safe removal are necessary to prevent serious aspiration complications.</div></div>","PeriodicalId":45034,"journal":{"name":"Journal of Oral and Maxillofacial Surgery Medicine and Pathology","volume":"37 1","pages":"Pages 104-107"},"PeriodicalIF":0.4,"publicationDate":"2024-05-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141051016","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

No conjunctival or cutaneous lesions were observed. Histopathological examination revealed a subepithelial split with inflammatory cell infiltration of the epithelial and connective tissues. Direct immunofluorescence revealed a linear deposition of C3 in the BMZ. IgG autoantibodies against BP230 were detected using an enzyme-linked immunosorbent assay. Indirect immunofluorescence using 1 mol/L NaCl-split skin sections revealed no reactivity for serum IgG or IgA. Immunoblotting using normal human epidermal extract as a substrate did not detect IgG reactivity against the 230-kDa antigen. Based on the above results, the definitive diagnosis of MMP with anti-BP230 antibody alone was established. Our case was categorized as low-risk MMP. The patient was treated with 0.1% triamcinolone acetonide ointment, oral minocycline, and oral nicotinamide, which improved the oral erosions.
