A 21 years old patient was operated by her choice with the ultrasonographic diagnosis of a 27*16 mm fibroadenoma. The pahtological evaluation detected ductal carcinoma insitu situated inside the fibroadenoma. Some authorities prefer to enucleate the fibroadenomas while the others prefer a diagnostic biopsy and a long term follow up because fibroadenomas are usually detected in young women at ages that cancer is rarely diagnosed. Although ductal carcinoma insitu situated inside fibroadenomas has been reported before the treatment is controversial. Local excision with radiotherapy is the most popular choice. But in our case the ductal carcinoma insitu was totally inside the adenoma and regarding the side effects in such a young age radiotherapy was ommited. The follow up of the other fibroadenomas detected by magnetic resonance imaging is also contoversial.trinfo:eu-repo/semantics/closedAccessFibroadenomaMalignantDuctal Carcinoma InsituArticle20542048WOS:000218551000009N/A
