<p>First degree burn = Only epidermis is affected, characterized by mild pain and erythema (redness), will heal in two to three days and may be accompanied by flaking and peeling Second degree burn = Extends through the entire epidermis and part of the dermis, Erythema, pain and blistering develops in the area of the damaged skin, Heals within 10 to 14 days with little scarring depending on extent of burn Third degree burn = Entire thickness of skin is destroyed, surface is leathery and may be tan, brown or black in appearance, no pain in immediate area because pain receptors are destroyed, regeneration of tissue is slow with much scarring even with grafts</p> Signup and view all the answers

<p>Basal Cell Carcinoma = Most common type, least malignant, slow-growing, rarely metastasizes Squamous Cell Carcinoma = Arises from the keratinocytes of the stratum spinosum, tends to metastasize to nearby lymph nodes if not removed Melanoma = Cancer of melanocytes, highly metastatic and resistant to chemotherapy</p> Signup and view all the answers

<p>Stratum Basale = Deepest layer of the epidermis, actively mitotic, cells undergo rapid division Stratum Corneum = Outermost layer of the epidermis, composed of dead, keratinized cells Stratum Spinosum = Cells contain a weblike system of intermediate prekeratin filaments attached to desmosomes, abundant melanin granules and dendritic cells</p> Signup and view all the answers
