Warts WARTS!!! • Caused by Human Papillomavirus (HPV) WARTS!!! • Caused by HPV WARTS!!! • Caused by HPV WARTS!!! • Foot or Plantar Warts Neoplasms 3. Skin Cancer Skin Cancer • Most common cancer –20% will develop one • Benign – does not spread to other parts Skin Cancer • Malignant – spreads to other organs –Metastasis – process of spreading Skin Cancers • UV radiation Sun-induced A. Basal Cell Carcinoma • Basal Layer • Least malignant • Most common Basal Cell Carcinoma • Invades dermis and hypodermis Basal Cell Carcinoma Shiny dome-shaped nodules Basal Cell Carcinoma Mainly in fair- complexions Basal Cell Carcinoma Tx – Surgical Removal Cure rate – 99% B. Squamous Cell Carcinoma • 2nd Most Common • Stratum granulosum • Scaly, reddened, and raised border Squamous Cell Carcinoma Squamous Cell Carcinoma • If removed, usually complete cure Squamous Cell Carcinoma Metastasis can occur C. Malignant Melanoma • Cancer of Melanocytes • ~5 % of skin cancers Malignant Melanoma • Numbers increasing • Prognosis: Poor • Most deadly of 3 –50% survival w/ treatment • Rapid metastasis Malignant Melanoma • Wherever there is melanin Malignant Melanoma • Look for new moles or pigmented spots that appear – ABCD rule for recognizing melanoma A – B – C – Ds of Melanoma •Asymmetrical –2 sides do NOT match A – B – C – Ds of Melanoma • Border – Uneven edges A – B – C – Ds of Melanoma •Color change –Spot contains different colors A – B – C – Ds of Melanoma •Diameter –Spot larger than 5mm (pencil eraser)
