* Ductal carcinoma in situ arising in tubular adenoma of the breast.
- We herein report an extremely rare case of ductal carcinoma in situ (DCIS) arising in tubular adenoma of the breast. A 33-year-old female first noticed a mass in her right breast when she was 15 years old. The tumor had not changed in size subjectively for 18 years. She finally visited the hospital one and a half years before this presentation for an examination of her breast mass. Ultrasonography (US) showed a circumscribed mass suggesting a benign tumor, and mammography (MMG) revealed the well-defined high-density mass with a focal region of microcalcification. It was suspected to be adenosis based on a core-needle biopsy (CNB). During the regular follow-up, the microcalcification in the mass increased. She was therefore referred to our hospital for further examination. US and MMG showed a well-demarcated mass with a focal microcalcified area. US-guided CNB diagnosed it as DCIS with tubular adenoma. The patient underwent tumorectomy. Histologically, the tumor was diagnosed to be DCIS in tubular adenoma with negative surgical margins.
