Summary
Granulomatous mastitis in pregnancy is rare but treatable. Early corticosteroid treatment can effectively manage this benign breast condition and prevent unnecessary biopsies.
Area of Science:
- Obstetrics and Gynecology
- Pathology
- Dermatology
Background:
- Granulomatous mastitis is a rare, benign breast condition often misdiagnosed as inflammatory breast cancer.
- While reported in reproductive-age women, it is an unusual presentation during pregnancy.
Observation:
- A 25-year-old pregnant woman presented with a large, tender breast mass at 17 weeks' gestation.
- The mass did not respond to antibiotics or surgical drainage.
Findings:
- Biopsy confirmed granulomatous mastitis.
- Corticosteroid therapy led to improvement of the condition.
- A postpartum recurrence also responded favorably to steroid treatment.
Implications:
- Early clinical and histological diagnosis of granulomatous mastitis is crucial.
- Prompt initiation of corticosteroid treatment may prevent extensive surgical interventions and disfigurement.
- This case highlights the importance of considering granulomatous mastitis in pregnant patients with breast masses.
