Juvenile papillomatosis (JP) is a very rare benign proliferative breast disease, especially in young women under 30 years of age. Its etiology is not clear yet. Although some patients have breast cancer in their family history, up to 10% breast cancer can develop in the follow-up of JP patients. In this pathology, which is diagnosed with biopsy, history, clinical and radiological findings help in diagnosis. In this case report, a 37-year-old patient diagnosed with JP will be discussed in the light of the literature.
