Squamous cell carcinoma - invasive

Squamous cell carcinoma - invasive


This irregular red nodule is an invasive squamous cell carcinoma (a form of skin cancer). Initial appearance, shown here, may be very similar to a noncancerous growth called a keratoacanthoma. Squamous cell cancers can metastasize (spread) and should be removed surgically as soon as they are diagnosed.
