Respiratory epithelial adenomatoid hamartoma (REAH) of the nasopharynx with high 18F-FDG uptake on PET/CT

Respiratory epithelial adenomatoid hamartoma (REAH) of the nasopharynx with high 18F-FDG uptake on PET/CT. Respiratory epithelial adenomatoid hamartoma (REAH) is a rare benign non-neoplastic sinonasal lesion that usually presents in the nasal cavity, paranasal sinuses, or olfactory cleft. We report a case of nasopharynx REAH mimicking a malignant tumour with incidental high 18-FDG uptake in a patient with colon cancer. Less than five similar cases have been reported to date, and this is the first case of REAH to show high uptake on PET/CT scans. Although hamartoma arising from the nasopharynx region is very rare, it should be considered in the differential diagnosis because it is a benign lesion and complete surgical resection is curative.
