Bottom Line: 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.

ABSTRACT
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.

Mentions: A physical examination revealed a discrete and freely movable mass 5 cm in diameter beneath the nipple in her right breast. There was no nipple discharge. She had no history of oral contraceptive use or pregnancy. US revealed a well-demarcated hypoechoic mass 4.7 cm in diameter, and a focal hyperechoic area with an echogenic spot 1.2 cm in diameter within it (Fig. 1). MMG showed a circumscribed high-density mass with a grouped punctated or amorphous microcalcification in the mass, whose area was about the same as the focal hyperechoic area on US (Fig. 2). The calcified area was suggested to be malignancy, although the whole mass was thought to be benign. Computed tomography (CT) revealed a well-defined enhanced mass in the right breast. Dynamic contrast-enhanced magnetic resonance imaging (MRI) disclosed a circumscribed enhanced mass with a rapid-plateau pattern. Both CT and MRI could not identify the cancerous lesion within the tumor. US-guided CNB from the hyperechoic area diagnosed it to be DCIS in tubular adenoma.Fig. 1
