How is clinical presentation of squamous cell carcinoma?

• SCC presents as a raised, firm, skin-colored or pink, often keratotic papule or plaque on a background of severely sundamaged skin, with: • mottled pigmentary alteration • telangiectasias • the presence of multiple actinic keratoses • Bowen disease presents as a slow-growing, irregular, sharply circumscribed, erythematous, velvety, or scaly plaque on sun-exposed or sun-protected skin • Marjolin ulcers should be considered in any chronic ulcer that fails to heal or which demonstrates a changing appearance
