Squamous Cell Carcinoma
Squamous Cell Carcinoma
These sun-induced tumors often resemble a rough, dry, painful plaque, or a dome-shaped mound resembling a small volcano. They often arise from preexisting actinic keratoses, but can eventually spread to adjacent skin (eyes, nose, lips or ears), lymph nodes , or other organs. To diagnosis squamous cell carcinoma, a biopsy must be performed, followed by excision if positive.
