A 50-year old African-American male comes into the clinic complaining of rough and blotchy skin around the top of his right ear. He states that the symptoms started bothering him about 1-month ago, he had a friend looked at the skin irritation and told was told that the skin looked discolored as well. He tells you that he worked as a road repair supervisor for the last 15-years after 10-years working as a paver, since graduating from college and not making a roster of the local baseball team. After performing an exam, you notice that the skin is in fact discolored and scaly around the apex of the ear, as well several other patches of similar discolored regions along his neck. Taking a tissue sample to be sent to the lab for analysis, you ask if he uses any type of sunscreen or wears protective clothing while on the job. To your amazement, he scoffs and reminds you that he is African American and does not have to worry about such things. The lab results comeback with the findings of squamous cell carcinoma in the sample sent. Based on your current understanding of Human Anatomy and Physiology, and with the use of correct medical/scientific terminology, generate a 2-3 paragraph response with a diagramed feedback loop describing the physiology of the case, that indicates the systems of the body that are impacted and the physiology of that system which was impacted, include in your response: What is the possible rationale, the most likely cause (etiology), for the diagnosis? What is the most likely treatment that can be utilized? Further, refute the statement made by the male about his genealogy protecting him from the development of skin cancer. In 1 paragraph, and using lay terminology and your understanding of human Anatomy and Physiology, walk your patient through the findings, conclusions, and treatment options.
