  1. Tzanck smear revealing multinucleated giant cells is consistent with infection caused by which organism?

    Answer: Herpes simplex virus

    Multinucleated giant cells (Tzanck cells) on smear are pathognomonic for herpesvirus infections, including HSV-1, HSV-2, and varicella-zoster virus.

  2. Which topical medication is the treatment of choice for tinea pedis (athlete's foot)?

    Answer: Topical clotrimazole or terbinafine

    Tinea pedis is a dermatophyte fungal infection treated with topical antifungals such as clotrimazole (azole) or terbinafine (allylamine) applied for 2–4 weeks.

  3. A patient on a biologic therapy for psoriasis should be screened for which infection before initiating treatment?

    Answer: Latent tuberculosis

    TNF-alpha inhibitors and other biologics used for psoriasis increase the risk of reactivating latent TB; a tuberculin skin test or IGRA must be performed before initiation.

  4. What is the most common cause of bacterial impetigo in children in the United States?

    Answer: Staphylococcus aureus (including MRSA)

    Staphylococcus aureus is the predominant cause of impetigo in the US, with MRSA increasingly common; it presents as honey-crusted lesions on the face and extremities.

  5. A patient reports a skin lesion that began as a papule and developed a central depression with umbilication. What is the most likely diagnosis?

    Answer: Molluscum contagiosum

    Molluscum contagiosum, caused by a poxvirus, produces dome-shaped papules with a characteristic central umbilication (depression) that distinguish it from other skin lesions.

  6. Which skin finding is most associated with systemic lupus erythematosus (SLE)?

    Answer: Butterfly (malar) rash across the nose and cheeks

    The malar (butterfly) rash of SLE spares the nasolabial folds and is triggered or worsened by UV light exposure, representing a classic diagnostic criterion.
