Early esophageal cancer based on the general morphology of specimens can be divided into four types of early esophageal cancer.
Credits under the general form of early esophageal cancer type 1. HIDDEN
In fresh specimens, the lesion is slightly rough, deep mucosa than normal color, no uplift and depression, positive exfoliated cells can be used as a diagnostic basis. Formalin-fixed specimens, the lesions become obvious, only to see the primary disorder of esophageal mucosal folds male, minor surface subsidence. Apart from this type of smear hyperplasia and cancer than the general non-inflammatory exudate, smear with clear background. Most lesions of length less than 1cm, histology, mostly intraepithelial carcinoma (carcinoma in situ) is the earliest stage of esophageal cancer, easily missed diagnosis in endoscopy.
Early esophageal cancer based on the general form of typing 2. erosive
Mild erosive mucosal lesions or slightly sunken, irregular margin, showing the map-like, clear boundaries with normal tissue, erosion and granular region, color dark red, occasionally residual normal mucosa area, surgical resection of early esophageal cancer in the more common. Apart from this type of smear outside hyperplasia and cancer cells, often more or less of the inflammatory exudate, lesion length 1 – 4cm range biopsy revealed mucosal lesions often confined to the lamina propria.
Credits under the general form of early esophageal cancer type 3. Plaque
Mucosal lesions of the limitations of uplift was gray patches, leather addiction was like change, boundary clearly visible on the surface a few mild plaque erosion, longitudinal fold of esophageal mucosa bags break, and horizontal wrinkles men should thicken, disorder and disruption. Lesions of different sizes, a few can affect the esophagus for the week. Section dense texture, the thickness of 3mm or more, the majority of this type of smear well differentiated cancer cells, and sometimes shows a small number of inflammatory cells, more than half of lesions were 2 – 4cm, biopsy revealed lesions invaded the muscularis mucosa or submucosa for early invasive cancer.
Credits under the general form of early esophageal cancer type 4. Papillary type or protruding
Nodular tumor was the exogenous uplift, papillary or polypoid broke into the lumen, the basement has a narrow or wide pedicle pedicle, tumor diameter, 1 – 3cm, clear boundaries with the surrounding normal mucosa, surface erosion, off-white homogeneous cut surface shape .
This type of smear generally well-differentiated cancer cells, few inflammatory cells. This type of early esophageal cancer in the older than the fly.
