Giant Lactating Adenoma With Fibroadenomated Changes

Area of Science:

• Obstetrics and Gynecology
• Surgical Oncology
• Pathology

Background:

• Lactating adenomas (LAs) are uncommon benign breast tumors.
• They typically manifest during late pregnancy or the lactation period.
• LAs are among the most prevalent breast lesions during the puerperium.

Observation:

• Lactating adenomas commonly present as painless, rapidly growing, large, mobile breast lumps.
• These tumors often appear late in pregnancy or the postpartum period.
• A core biopsy is usually necessary to rule out malignancy.

Findings:

• A case of a 34-year-old patient with a rapidly enlarging pre-existing right breast lump is presented.
• The lump significantly increased in size during pregnancy.
• Surgical excision was performed shortly after delivery.

Implications:

• This case underscores the importance of diagnostic evaluation for rapidly growing breast masses during pregnancy and postpartum.
• Surgical intervention can provide both diagnostic certainty and satisfactory cosmetic results for lactating adenomas.
• Understanding the presentation and management of lactating adenomas is crucial for obstetricians, gynecologists, and breast surgeons.
