Two Uncommon Cases of Chyle Leakage After Modified Radical Mastectomy for Breast Cancer

Chyle leakage is a rare benign complication that can occur after axillary lymph node dissection. It may delay wound healing, extend hospitalization, impair the immune system, and affect the start time of adjuvant therapy. We herein present two cases of chyle leakage following left-side modified radical mastectomy in two patients with invasive carcinoma of the left breast. In such cases, treatment should begin with conservative measures, including reducing lymph production and flow. When a conservative strategy is unsuccessful, surgery or interventional procedures are necessary. Breast surgeons should be mindful of possible chyle leakage when operating in the axilla and be familiar with its treatment.
