Depressed-type (0-IIc) colorectal neoplasm in patients with family history of first-degree relatives with colorectal cancer: A cross-sectional study

Figure 2 Histological findings. A: Low-power histological view of a cut section of the resected specimen confirmed Dukes’ A (T1 stage) carcinoma with invasion to the submucosa. B: High-power histological view confirmed a well differentiated adenocarcinoma invading 1000 μm below the muscularis mucosa.

Figure 1 Superficial depressed lesion (0-IIc). A: A superficial depressed lesion (0-IIc) of the transverse colon, 27 mm in diameter. Initially it was recognized as a broad patch of erythema and deformity of the haustrum. The patient demonstrated a family history of CRC. His mother had a past history of sigmoid colon cancer at age of 65 years. B: After dye spraying, an absolutely depressed area could be clearly identified, with a slightly elevated margin.
