Squamous Cell Carcinoma
Squamous Cell Carcinoma (SCC) often presents as an erythematous papule or nodule that is hyperkeratotic or scaly. These lesions can be slow-growing or rapidly enlarging, and once advanced, may exhibit ulceration and friability. SCC evolves over time from precursor lesions such as actinic keratosis, but can also develop rapidly as de novo lesions especially in immunosuppressed patients or severely sun damaged skin. In darker skin patients, squamous cell cancers more commonly develop within nonhealing chronic wounds and scars.
