Galactocele and prolactinoma--a pathogenic association?

Area of Science:

• Endocrinology
• Oncology
• Pathology

Background:

• Galactocele is a benign breast lesion caused by obstructed milk ducts, usually in postpartum women.
• Cases unrelated to lactation are rare, occurring in postmenopausal women or men.
• The link between galactocele and prolactin overproduction is not well-established.

Observation:

• A 37-year-old female patient with no history of childbirth or abortion presented with a galactocele.
• The patient was diagnosed with both a microprolactinoma and a galactocele.
• The size of the galactocele appeared to correlate with the pituitary tumor's progression and serum prolactin levels.

Findings:

• This case presents an unusual association of galactocele in a young woman without a history of lactation.
• Elevated prolactin levels due to a microprolactinoma are identified as the most probable cause of the galactocele.
• The study suggests a hormonal etiology for mammary galactocele in the absence of other identifiable causes.

Implications:

• This case underscores the importance of considering hormonal influences, specifically prolactin excess, in the development of breast lesions like galactocele.
• It highlights the need for further research into the relationship between endocrine disorders and benign breast conditions.
• Recognizing this association can aid in diagnosing and managing rare cases of galactocele, particularly in women without typical risk factors.
