はじめに

　乳輪乳頭の疾患について，乳腺外科医の立場から，日常診療でよく遭遇する主訴や所見，乳癌との鑑別が必要なものなどについてまとめた。

　Diseases of the nipple and areola are often detected by perceptible symptoms and are often the main complaint in visits to a breast outpatient clinic. We provide an overview of the development, anatomy, and physiological changes of the nipple and areola, and we then summarize diseases of the nipple and areola based on the main complaints and findings commonly encountered in daily practice, from the perspective of a breast surgeon. If there are any nipple or areola findings that are suggest any malignancy, an examination by a breast surgeon is necessary. The importance of patients’ breast awareness should also be promoted at times other than check-ups.
