Solitary Hard Palate Langerhans Cell Histiocytosis Demonstrated on PET/CT Scan in an Adult

Langerhans cell histiocytosis (LCH) is rare in adults. Oral and maxillofacial LCH commonly affects the bones of the skull and jaws. Here we report a case of a 57-year-old man with a painless oral mass evaluated by 18F-FDG PET/CT. PET/CT showed a solitary 18F-FDG-avid tumor in his left hard palate. LCH was confirmed after surgery. This case reminds us that LCH should be considered in an adult with hypermetabolic hard palate lesion on 18F-FDG PET/CT.
