Dean is a 40 year old aging beach boy. Although his suntan made him more popular when he was young, his face is now all wrinkled. He also has a darkly pigmented mole on his back that has irregular borders and is about the size of a dime. Dean goes to the doctor and explains that this mole was hardly noticeable until recently and has grown rapidly. In the past few months, the mole has started itching and bleeding. A skin biopsy report states that Dean has skin cancer. What type of skin cancer does Dean have?

Based on the symptoms described, Dean likely has melanoma, a type of skin cancer. The rapidly growing, darkly pigmented mole with irregular borders, along with itching and bleeding, are characteristic signs of melanoma.

Melanomas can develop from existing moles, and they often have irregular borders, change in size, itch, and bleed. Additionally, the fact that the mole has grown rapidly and become more noticeable in a short period of time is also a concerning symptom for melanoma. It is important for Dean to follow up with his doctor for further evaluation and treatment.
