25. The correct answer is B. This rash is tinea versicolor. It is best treated with topical anti-fungals such as miconazole. Prednisone is effective in contact dermatitis, allergic rashes, and steroid responsive dermatoses. Triamcinolone is good for localized dermatitis. Diphenhydramine is great for itching for symptomatic relief and to help in allergic rashes.

24. A is the correct answer. Pyogenic granulomas typically occur on the digits and can occur after a minor trauma. Treatment is usually surgical excision. They typically have a minor trauma before they appear but not always. Carbuncles do not have this type of appearance. They are skin covered and have some induration and do usually occur on the digits. Malignant melanoma has a black or purple appearance usually and is not raised. Squamous cell carcinoma is usually not that raised and does not have that dark red fleshy appearance.

23. B is the correct answer. HSP is a vasculitis that typically comes after a respiratory infection. It is a vasculitis that can cause blood an protein in the urine. It can also cause renal problems so that needs to be monitored. Scabies is incorrect because the rash does not look like that and will not give you fever, abdominal pain, joint pain, or blood/protein in the urine. Meningococcemia can give you a petechial rash but will not cause abdominal pain or joint pain or swelling. Rocky Mountain Spotted Fever does not give you a purple rash like seen in the picture.
