Ductal Carcinoma In situ with Focal Invasion Arising in Fibroadenoma: A Case Report and Review of Literature

Fibroadenoma is the most commonly diagnosed benign tumor of the breast with highest occurrence in adolescent and young women. Its coexistence with invasive ductal carcinoma is extremely rare and infrequently reported. We report a case of 30-year-old female who was diagnosed with extensive ductal carcinoma in situ with focal invasion within fibroadenoma on lumpectomy. The carcinoma was detected incidentally on histopathological examination. Therefore a careful and extensive sampling of the tissue is required to prevent a false negative diagnosis by pathologists.
