Squamous cell carcinoma typically develops in sun-damaged skin in fair-skinned patients. Squamous cell carcinomas, a type of skin cancer, can appear as a round, red mass, typically on a sun-exposed location. Large, white, slightly elevated lesions and an erosion of the tongue are signs of an oral squamous cell carcinoma. As displayed in this early squamous cell carcinoma, a small, elevated lesion may be accompanied with scale or a crust. Squamous cell carcinoma can involve the fingertip and begin under the fingernail, as displayed here. Squamous cell carcinoma frequently appears on the face, as displayed in this image. This image displays a bleeding lesion typical of squamous cell carcinoma. This image displays squamous cell carcinoma on the nose, a frequent location due to chronic sun exposure.

This image displays a crusting and bleeding lesion on the lower lip typical of squamous cell carcinoma. This image displays multiple areas of sun damage and a large squamous cell carcinoma on the middle finger. This squamous cell carcinoma under the toenail has a pink to brown streak of discoloration of the nail plate as well as a thickened, rough area at the edge and under the nail plate. Due to chronic sun exposure, this foot had sun-induced freckles; a bleeding lesion; and a large, scaling lesion typical of squamous cell carcinoma.
