We report a case of oxyphilic cell adenoma of the thyroid gland in a 79-year-old female. Fine needle aspiration cytology revealed isolated or sheetly-arranged tumor cells which had abundant eosinophilic granular cytoplasm. Eccentric nuclei showed intranuclear cytoplasmic inclusions and grooves. Histologically, a follicular adenoma, oxyphilic cell type was well-encapsulated and did not show vascular invasion or metastasis.
