Summary
This case study details a rare giant lactating adenoma, a benign breast lesion, presenting unusually large and with concerning features. Pathological examination confirmed the diagnosis despite initial clinical-radiologic concerns.
Area of Science:
- Breast pathology
- Reproductive endocrinology
- Surgical oncology
Background:
- Lactating adenoma is a rare, benign breast lesion typically presenting as a small, well-circumscribed mass.
- It most commonly affects women aged 20-40 during the third trimester of pregnancy.
Observation:
- This case features an unusually large lactating adenoma (>10 cm) with multiple nodules and poorly defined ultrasonographic margins.
- Radiologic features were concerning, mimicking malignancy or infection, with growth noted since early pregnancy.
- The lesion was associated with chronic mastitis and presented with infarction.
Findings:
- Clinical-radiologic differential diagnoses included abscess, phyllodes tumor, and galactocele.
- Pathologic examination confirmed lactating adenoma with multiple infarcted areas.
- This represents an unexpected case of giant lactating adenoma.
Implications:
- Highlights the importance of considering benign lesions even with concerning clinical and radiologic features.
- Emphasizes the need for accurate pathological diagnosis in differentiating giant breast masses.
- Contributes to understanding the spectrum of lactating adenoma presentations.
