a case report

Fibroadenomas are the most common benign breast neoplasms. In rare cases, a carcinoma may develop within a fibroadenoma. The aim of this study was to report a case of low-grade carcinoma in situ in a fibroadenoma. A 31-year-old female, G0P0A0 and without family history of cancer, arrives at the service with an expressive breast lump growth along the year year. Core biopsy, histopathological and immunohistochemical studies showed an in-situ carcinoma in a fibroadenoma. Surgical resection was performed with a safety margin, and anatomopathological study and immunohistochemistry of the surgical specimen confirmed the core biopsy diagnosis. Currently, the patient is under annual clinical follow-up with mammography and breast ultrasound and no evidence of neoplastic disease. Although this is a rare event and few cases are described in the literature, carcinomas in situ can occur in a fibroadenoma.
