My answer is c) Poxvirus. I think the image shows a penis infected with Molluscum contagiosum, even though you can not really see if the lesions are ombilicated or not.

The correct answer is C. This is a classic case of molluscum contagiosum caused by the poxvirus. Physical examination is significant for pearly white or skin-colored nodules with central umbilication on the genitals and trunk. Molluscum contagiosum is a benign skin disease transmitted by sexual contact, clothes, or towels. It often resolves spontaneously but may require topical therapy or surgery in immunocompromised patients.

Answer A is incorrect. HSV type 1 affects mucosal surfaces, particularly oral mucosa. Erythema is the first sign of infection, followed by grouped vesicles that evolve to pustules. Pustules erode, then ulcerate, commonly producing a crust. Lesions resolve spontaneously without scar within 24 weeks.

Answer B is incorrect. Human herpesvirus 8 is thought to be the causative factor of Kaposi's sarcoma. These lesions are purple/red/blue and are most common in patients with AIDS.

Answer D is incorrect. Rubeola virus is another name for the RNA virus that causes measles, an exanthematous disease that begins as Koplik's spots on the oral mucosa and progresses to a maculopapular rash. Prodromal syndromes of malaise and fever are common.

Answer E is incorrect. VZV is the causative agent in chickenpox. It is a highly contagious DNA herpesvirus transmitted by respiratory droplets or by direct contact. The virus, characterized by recurrent crops of lesions classically described as "dew-drops on a rose petal," is commonly seen on the face and trunk. VZV infections are often accompanied by prodromal symptoms of fever and malaise.
