Area of Science:

  • Pathology
  • Oncology
  • Histology

Background:

  • Breast lesions with mucin encompass a wide range of conditions.
  • These include benign changes, mucocele-like lesions (MLL), and malignant tumors.

Purpose of the Study:

  • To delineate the spectrum of breast lesions containing mucin.
  • To discuss diagnostic challenges and histological differentials.
  • To provide a practical approach for resolving diagnostic issues.

Main Methods:

  • Histopathological analysis of breast lesions with mucin.
  • Review of differential diagnoses.
  • Discussion of diagnostic criteria.

Main Results:

  • Breast lesions with mucin range from benign fibrocystic changes to MLL, atypical ductal hyperplasia, ductal carcinoma in situ, and invasive mucinous carcinoma.
  • MLL can be associated with various epithelial alterations.
  • Rare entities may exhibit both epithelial and stromal mucin.

Conclusions:

  • Accurate diagnosis of mucinous breast lesions requires careful histopathological evaluation.
  • Distinguishing benign from malignant entities is crucial.
  • A systematic approach aids in managing these diverse lesions.
