Question: What is a condition unique to geriatrics in dermatology? One condition seen predominantly in the geriatric population is senile purpura, also called actinic purpura. This occurs due to age-related dermal thinning, loss of subcutaneous fat, and cumulative sun exposure. Even minor trauma can cause large, dark purple ecchymoses on the forearms and hands. While benign, it can be distressing for patients and is important to differentiate from bleeding disorders or medication-induced bruising (such as with anticoagulants). What is a condition likely to be seen in the emergency department? A dermatologic condition often encountered in the ED is Stevens-Johnson syndrome (SJS)/toxic epidermal necrolysis (TEN). This is a severe mucocutaneous reaction, usually triggered by medications (e.g., sulfa drugs, anticonvulsants, allopurinol). It presents with painful erythematous or dusky macules, mucosal involvement, and epidermal detachment. Because of the risk of fluid/electrolyte imbalance, sepsis, and high mortality, SJS/TEN is treated as a medical emergency, often requiring ICU or burn-unit level care. What is one thing about dermatology cancer treatment you learned this week? One thing I learned about dermatology cancer treatment this week is how much outcomes depend on early detection of melanoma. When caught early, the 5-year survival rate is about 98%, but this drops to 62% with lymph node involvement and only 18% with distant metastasis. Need Assignment Help?
