The galactorrhoea-endometriosis syndrome

Area of Science:

• Reproductive endocrinology
• Gynecology

Background:

• Endometriosis is a common gynecological condition.
• Galactorrhoea, or milky nipple discharge, can have various causes.
• A potential association between these two conditions has been observed.

Purpose of the Study:

• To describe a newly recognized syndrome characterized by the co-occurrence of galactorrhoea and endometriosis.
• To report clinical observations of patients presenting with both conditions.

Main Methods:

• Case series describing nine patients with endometriosis.
• Observation of galactorrhoea in eight patients, either at diagnosis or post-treatment with danazol.
• Measurement of prolactin levels in seven patients.

Main Results:

• A syndrome of galactorrhoea and endometriosis is described.
• Eight out of nine endometriosis patients experienced galactorrhoea.
• Prolactin levels were normal in the majority of patients assessed.
• Galactorrhoea can occur in women with regular menses and a history of dysmenorrhoea.

Conclusions:

• Galactorrhoea in women with regular menstrual cycles may indicate underlying endometriosis.
• This association is particularly relevant in patients with a history of painful periods (dysmenorrhoea).
• Further investigation into the pathophysiology linking these two conditions is warranted.
