Summary
We experienced two cases of superficial type esophageal cancer. Case 1 was a 72-year-old man in whom endoscopic examination revealed a slightly protruded, partially reddened and faded area of irregular shape corresponding to 0-IIa + IIc (slightly depressed type) of the endoscopic classification of esophageal cancers. Macroscopically, it was a superficial, ill-defined and non-cicatrized solitary tumor measuring 2.5 × 2.4 cm in size. Histologically it was a monofocal semidifferentiated squamous cell carcinoma of a swelling type of stage 0. Case 2 was 55-year-old man. Endoscopic examination disclosed an almost roundish, smooth-surfaced, flat and dull red area corresponding to IIc (slightly depressed type). Macroscopically it was a superficial, semidefined and non-cicatrized solitary tumor measuring 1.0 × 1.0 cm in size. Histologically it was a monofocal, semidifferentiated squamous cell carcinoma of stage 0.
To detect esophageal cancer at an early stage, the endoscopist needs to inspect the mucosa carefully. In case of males aged over 50, the endoscopist would be well advised to employ the dye-spraying method (Lugol staining method) at the endoscopic examination.
