 Clinicians desire to understand the importance of contrasting endoscopic and pathologic images of carcinomas in the pharynx and esophagus. Recently, diagnosis of carcinomas has frequently been made by evaluating surface structures and vascular findings in a narrow area using narrow-band imaging magnifying endoscopy, which requires an accurate histopathological image of the region of interest. Hence, obtaining a clear and bright image and finding a marker for contrast are important ; in particular, the two-point marking method between the regions of interest is useful. Furthermore, it is essential to process the resected specimen appropriately, including prompt attachment of the resected lesion, fixation, image capture, and interdigitation after fixation. Additionally, accurate mapping by the pathologist is crucial. After carefully conducting each of the above steps, the endoscopic image and fixed specimen mapping image are compared using various indices, including two-point marking, to generate a histopathological image of the region of interest, thereby achieving the distinction.
