General Classification of Nipple Discharge

• Nipple discharge is first categorized as either physiological or pathological to determine the necessary clinical pathway.

• Physiological discharge is typically bilateral, involves multiple ducts, and is milky in appearance, which is known as galactorrhea.

• Pathological discharge is characterized as spontaneous, unilateral, arising from a single duct, and being serous or blood-stained.

• Clinical management for physiological discharge focuses on systemic or endocrine evaluation, while pathological discharge requires the Triple Assessment protocol.

  
  

The Triple Assessment Protocol

• Step 1 involves a thorough clinical history and physical examination to identify discharge characteristics and any associated masses.

• Step 2 is diagnostic imaging, utilizing ultrasound for women under 40 and mammography for women over 40.

• Step 3 consists of histopathology, which may involve a core needle biopsy of an identified lesion or a microdochectomy for single-duct discharge.

  
  

  1.Intraductal Papilloma

• This is the most common cause of spontaneous, single-duct, blood-stained discharge and is a benign epithelial tumor arising in a large lactiferous duct.

• Imaging may show a small solid nodule within a dilated duct, although mammograms are often normal.

• The gold-standard treatment is a microdochectomy, which involves the surgical excision of the affected duct and serves both diagnostic and therapeutic purposes.

  
  

  2.Intraductal Carcinoma (DCIS)

• Ductal Carcinoma In Situ can present with a spontaneous, bloody discharge identical to a benign papilloma, making clinical differentiation impossible.

• Diagnosis typically requires a mammogram to identify pleomorphic microcalcifications followed by a stereotactic core needle biopsy.

• Standard surgical management is a wide local excision with negative margins followed by whole-breast radiation.

  
  

3.Fibrocystic Disease (Fibroadenosis)

• This benign condition presents with a thick, greenish, toothpaste-like discharge that is expressed rather than spontaneous.

• The discharge arises from multiple ducts and is frequently associated with bilateral cyclical breast pain and diffuse nodularity.

• Management focuses on reassurance and advising the patient not to squeeze the breast, as expression stimulates further secretion.

  
  

4.Duct Ectasia

• Duct ectasia is a benign inflammatory condition of the large ducts common in perimenopausal women, resulting in a thick, sticky, greenish-brown multi-duct discharge.

• It can mimic malignancy because periductal fibrosis may cause nipple retraction and retroareolar thickening.

• Treatment involves observation for asymptomatic cases or a total duct excision, also known as Hadfield's operation, for persistent or bothersome symptoms.

  
  

5.Prolactinoma and Galactorrhea

• Galactorrhea is a milky, bilateral discharge from multiple ducts caused by hyperprolactinemia, often due to a pituitary microadenoma.

• Patients may also report systemic symptoms such as irregular periods, headaches, or visual field defects.

• Diagnosis is confirmed through serum prolactin levels and an MRI of the pituitary gland.

• Treatment is medical rather than surgical, utilizing dopamine agonists like cabergoline to resolve the discharge and shrink the tumor
