53-year-old female, breast carcinoma, left, S/P modified radical mastectomy ten years ago (in 2005)
She also received courses of chemotherapy until 2006. June 11th, 2015: Enlargement of bilateral inguinal lymph nodes, and more obvious over the right side, measuring up to 1.31 × 1.30 × 0.67 in dimensions. No mass or nodule is found over the rest body parts (Figure 1).
