Background: Syringomatous adenoma of the nipple is a benign, locally infiltrating tumor, that histologically resembles syringoma originating from a skin appendage.Case: The patient was an 87-years-old woman. A lump was discovered close to the nipple of her right mammary gland, during treatment for hypertension at our hospital. The tumor was about 1 cm in diameter. Fine needle aspiration cytology showed clusters of atypical cells, keratotic substances and multi-nuclear giant cells. Histologically, tubular, duct-like structures and keratinizing cysts were present. This case was finally diagnosed as syringomatous adenoma of the nipple.Conclusion: The presence of keratotic substances in the findings of aspiration cytology was thought to be characteristic of syringomatous adenoma.
