Light and Electron Microscopy Comparison of Squamous Carcinoma

Squamous cell carcinoma, or squamous carcinoma for short, also known as epidermoid carcinoma, is a kind of malignant tumor originating from squamous epithelium, which is commonly found in areas covered by squamous epithelium, such as the skin, the oral cavity, the lips, the esophagus, the cervix of the uterus, the vagina, etc. Squamous carcinomas are not commonly seen on cytomorphological examination of body fluids. It commonly results from infiltration of adjacent sites or metastasis from distant tumors. Most commonly, squamous cell carcinoma of the esophagus or lung bronchus metastasizes in the chest or infiltrates the lung bronchus, and squamous cell carcinoma evolving from metaplasia of the bladder or renal pelvis can be seen in urine or ascites, and squamous cell carcinomas of the cervix or vagina in females tend to be found in ascites.
