Ductal Carcinoma In Situ (DCIS)

Rodrigo Arrangoiz MS, MD, FACS, FSSO

Mammographic detection of calcification remains the mainstay of detection of nonpalpable malignancy.

  • The term ductal carcinoma in situ (DCIS) encompasses a heterogeneous group of lesions that differ in their clinical presentation, histologic appearance, and biological potential.

  • DCIS is characterized by proliferation of presumably malignant epithelial cells within the mammary ductal system, with no evidence of invasion into the surrounding stroma on routine light microscopic examination.

  • Classification schemes that divide DCIS histologically into a variety of subtypes emphasize architectural features or growth pattern of the neoplastic cells, cytologic features of ductal cells, and cell necrosis, both singly and in combination:

    • Comedo-type necrosis is characterized by prominent necrosis (eosin positive) in the center of the involved spaces.

    • The necrotic material frequently becomes calcified.

    • The tumor cells are large and show nuclear pleomorphism.

    • Mitotic activity may be prominent.
