case_images: The right colon mass was an adenocarcinoma (Fig. 3A) (T3N0), negative for deficient mismatch repair protein expression, B-RAF (B-type rapidly accelerated fibrosarcoma) and K-RAS (Kirsten rat sarcoma oncogene) mutation but positive for N-RAS (neuroblastoma RAS oncogene). Tumor-free margins were achieved (Fig. 3B).
