Summary

Microdochectomy effectively diagnoses and treats persistent nipple discharge from a single duct. This procedure is crucial for identifying ductal carcinoma, even without a palpable lump, offering a curative solution.

Area of Science:

  • Oncology
  • Surgical Pathology

Background:

  • Persistent nipple discharge from a single duct can be a symptom of underlying breast pathology.
  • Early detection of breast cancer is critical for successful treatment outcomes.

Purpose of the Study:

  • To evaluate the diagnostic and therapeutic efficacy of microdochectomy for persistent single-duct nipple discharge.
  • To determine the incidence of malignancy in patients undergoing microdochectomy for this indication.

Main Methods:

  • Retrospective analysis of 162 women who underwent microdochectomy for persistent single-duct nipple discharge.
  • Histopathological examination of resected ductal tissue to diagnose malignancy or hyperplasia.
  • Correlation of clinical presentation (discharge type, palpable lump) and mammographic findings with pathological results.

Main Results:

  • Invasive or in situ ductal carcinoma was diagnosed in 10% of patients (16/162), with no palpable lumps.
  • Blood-stained discharge was present in 14 of the 16 malignancy cases.
  • Mammography was abnormal in only 5 of the 16 diagnosed cancer patients, highlighting its limitations in this context.

Conclusions:

  • Microdochectomy is a definitive treatment for persistent single-duct nipple discharge, providing accurate diagnosis.
  • The procedure is essential for detecting occult breast cancers, including ductal carcinoma, which may not be evident on mammography or clinical examination.
  • Microdochectomy is the recommended treatment for single-duct nipple discharge, regardless of discharge color, due to its diagnostic and curative potential.
