Juvenile Papillomatosis of the Breast in a Pre-Pubertal Girl: An Uncommon Diagnosis.

Juvenile papillomatosis of the breast represents a rare benign proliferative disorder that affects women younger than thirty years of age. Although it is a localized lesion, it does not have well-demarcated margins. These patients tend to have a strong family history for cancer. As it has similar clinical presentation with that of a fibroadenoma, it usually receives the diagnosis of the latter in the preoperative period. Nonetheless, it has distinct microscopic features such as ductal papillomatosis and cysts that are helpful in the diagnosis. In this article, a case of juvenile papillomatosis diagnosed in a young girl who presented due to a mass of the breast was presented. For the fairly rare case, a total mass excision was performed with preserved breast tissue. The exact diagnosis was made by postoperative histopathological examination.
