  1. A 35-year-old woman presents with an 8 mm pigmented lesion on her foot showing amelanotic areas and nail involvement (melanonychia). What is the most important next diagnostic step?

    Answer: Dermoscopy and punch biopsy

    Acral lentiginous melanoma, the most common melanoma in darker-skinned individuals, can mimic benign lesions on the foot; biopsy is mandatory for any concerning pigmented acral lesion.

  2. A 19-year-old male presents with multiple firm, flesh-colored, umbilicated papules in the groin and inner thighs after sexual contact. What is the causative agent?

    Answer: Molluscum contagiosum virus (poxvirus)

    Molluscum contagiosum is caused by a poxvirus and presents with firm, umbilicated, flesh-colored papules; genital involvement in adults is sexually transmitted.

  3. A 48-year-old woman presents with thick, yellow, crumbling toenails with subungual debris and onycholysis. KOH preparation confirms dermatophyte infection. What is the preferred treatment for onychomycosis?

    Answer: Oral terbinafine for 12 weeks

    Oral terbinafine for 12 weeks (toenails) achieves significantly higher cure rates than topical agents for onychomycosis due to subungual penetration.

  4. A 50-year-old man presents with multiple velvety, brown-black warty plaques on his trunk that appear 'stuck on.' They have a cerebriform surface and vary in size. What is the diagnosis?

    Answer: Seborrheic keratosis

    Seborrheic keratoses are benign, pigmented, warty growths with a 'stuck-on' appearance and horn pseudocysts on dermoscopy; they require no treatment unless symptomatic.

  5. A 6-year-old child presents with a single circular patch of hair loss on the scalp with broken-off hairs at the scalp surface ('black dots') and mild scaling. Wood's lamp examination is negative. What is the treatment of choice?

    Answer: Oral griseofulvin

    Tinea capitis requires oral antifungal therapy (griseofulvin or terbinafine) because topical agents cannot penetrate the hair follicle adequately.

  6. A 70-year-old woman presents with a firm, painless, flesh-colored papule on her lower eyelid that has grown slowly over 2 years. The border is irregular and there is perineural invasion on biopsy. What subtype of cutaneous cancer is most aggressive?

    Answer: Morpheaform (sclerosing) basal cell carcinoma

    Morpheaform (sclerosing) BCC has the most aggressive behavior, with subclinical extension and perineural invasion, requiring Mohs surgery for adequate margins.

  7. A 32-year-old woman presents with pink, annular plaques with raised borders on her arms after hiking in the Southwest US. Serology confirms Coccidioides immitis infection. What skin finding is a sign of good immune response?

    Answer: Erythema nodosum

    Erythema nodosum (tender, red subcutaneous nodules on the shins) in coccidioidomycosis indicates a strong cell-mediated immune response and a favorable prognosis.
