Mammary analog secretory carcinoma

Last edited: 4/10/2026

Overview

Mammary analog secretory carcinoma (MASC) is a rare breast neoplasm characterized by prominent intracellular and intraacinar mucin 1. These tumors are analogous to similar, though rarer, tumors found in the breasts of children 1.

Diagnosis

  • Distinguished by gross and microscopic circumscription and prominent intracellular and intraacinar mucin 1.
  • Apparently slow-growing lesions 1.

    • Management

  • No specific management details are provided in the abstract.
  • None of the presented cases manifested local recurrence or metastases 1.

    • Special Populations

  • More characteristically occur in the breasts of children, though adult cases are presented 1.

    • Key Recommendations

  • Mammary analog secretory carcinoma is a breast neoplasm distinguished by gross and microscopic circumscription and prominent intracellular and intraacinar mucin 1. (Evidence: Weak)
  • These neoplasms are apparently slow-growing lesions 1. (Evidence: Weak)
  • None of the presented cases manifested either local recurrence or metastases 1. (Evidence: Weak)
