Abstract
Breast cancer is the predominant cancer affecting females in Australia. With the rising obesity rates, the number of obese breast cancer patients is also rising. Full complex breast reconstruction is known to carry significant risk of complications in obese patients, hence we sought to utilize Goldilocks mastectomy as an alternative middle-ground option between standard mastectomy and complex breast reconstruction. A 63-year-old obese female presented with left nipple inversion. Ultrasonography revealed a 9.7 mm dilated retroareolar duct within the left breast, indicating lobular carcinoma. Subsequent biopsy analysis revealed estrogen/progesterone receptor (ER/PR)-positive cancer with equivocal human epidermal growth factor receptor 2 (HER2) status and a Ki67 index of 10%. Concurrently, a discrete area of conspicuous breast tissue prominence displayed characteristics of invasive ductal carcinoma with similar receptor status but a reduced Ki67 index of less than 5%. Traditional breast reconstruction options were unfavorable due to obesity, prompting consideration of a tailored Goldilocks mastectomy. The procedure was uncomplicated, and follow-up assessments revealed commendable wound healing, alongside the restoration of symmetrical breast contours. Conclusion: This study highlights the significance of Goldilocks mastectomy as an invaluable technique in the comprehensive management of breast cancer, particularly for obese patients characterized by a body mass index (BMI) exceeding 35 and substantial medical comorbidities.
