CEA.
,Question 1
A 65-year-old fair-skinned farmer presents with a rough, scaly patch on his forehead. He states it
has been present for several months and occasionally bleeds when scratched. What is the most
likely diagnosis?
A) Seborrheic keratosis
B) Actinic keratosis
C) Basal cell carcinoma
D) Psoriasis
Rationale: Actinic keratosis is a precancerous skin lesion caused by chronic ultraviolet light
exposure. It commonly presents as a rough, gritty, scaly plaque on sun-exposed areas like the
face or scalp of older adults. Seborrheic keratosis is a benign "stuck-on" lesion. Basal cell
carcinoma typically appears pearly or waxy with rolled borders, while psoriasis causes well -
demarcated plaques with silvery scales on extensor surfaces.
Question 2
Which clinical feature is the single most important prognostic factor for a patient diagnosed
with malignant melanoma?
A) Breslow depth (tumor thickness)
B) Diameter of the lesion
C) Presence of ulceration
D) Asymmetry of the lesion
Rationale: Breslow depth measures the precise vertical thickness of the melanoma from the
top of the granular layer to the deepest point of tumor invasion. It is the most critical
prognostic indicator because deeper vertical growth strongly correlates with an increased risk
of lymph node metastasis and decreased overall survival. The other options represent
diagnostic criteria or staging factors but do not carry the same heavy prognostic weight.
Question 3
A 72-year-old male presents with a pearly, waxy papule on the tip of his nose with visible
arborizing telangiectasias. What is the most likely diagnosis?
A) Squamous cell carcinoma
B) Actinic keratosis
C) Basal cell carcinoma
D) Keratoacanthoma
,Rationale: Basal cell carcinoma is the most common form of skin cancer. Its classic clinical
presentation includes a shiny, pearly, or waxy nodule with central ulceration and prominent,
branching telangiectasias (blood vessels). Squamous cell carcinoma presents as a firm,
erythematous hyperkeratotic nodule. Actinic keratosis is a flat, rough patch, and
keratoacanthoma presents as a rapid-growing dome-shaped nodule with a central keratin
plug.
Question 4
A 55-year-old man presents with a firm, erythematous, hyperkeratotic nodule on his lower lip.
He is a heavy smoker and has a history of prolonged sun exposure. Biopsy reveals atypical
keratinocytes throughout the epidermis. What is the most likely diagnosis?
A) Actinic keratosis
B) Basal cell carcinoma
C) Seborrheic keratosis
D) Squamous cell carcinoma
Rationale: Squamous cell carcinoma commonly affects the lower lip in patients with a history
of tobacco use and chronic UV exposure. It characteristically presents as a firm, indurated,
scaling or crusting nodule that may ulcerate. Unlike actinic keratosis, which is a confined
precancerous lesion, squamous cell carcinoma demonstrates deep epidermal or dermal
involvement of atypical keratinocytes.
Question 5
A mother brings her 4-month-old infant in for an itchy, erythematous, weeping rash on the
cheeks and extensor surfaces of the arms. What is the first-line treatment for this condition?
A) High-potency topical corticosteroids
B) Emollients and low-potency topical corticosteroids
C) Oral antihistamines
D) Topical calcineurin inhibitors
Rationale: This presentation is classic for infantile atopic dermatitis (eczema), which favors
the face and extensor surfaces. First-line management focuses on restoring the skin barrier
with thick, fragrance-free emollients and reducing inflammation with low-potency topical
corticosteroids (e.g., hydrocortisone 1%). High-potency steroids are avoided on the infant face
due to thinning risks, and calcineurin inhibitors are not approved for infants under 2 years old.
, Question 6
A 30-year-old patient presents with well-demarcated erythematous plaques with silvery-white
scales on the knees and elbows. The patient also complains of joint stiffness in the mornings.
What is the most likely diagnosis?
A) Atopic dermatitis
B) Contact dermatitis
C) Lichen planus
D) Psoriasis
Rationale: Plaque psoriasis classically presents as well-demarcated, erythematous plaques
covered with silvery-white scales that favor extensor surfaces like the elbows and knees. Up to
30% of patients with psoriasis also develop psoriatic arthritis, which explains the morning
joint stiffness. Atopic dermatitis presents on flexor surfaces and lacks the silvery scales.
Question 7
A patient presents with multiple hypopigmented, scaly macules on the upper chest and back. A
potassium hydroxide (KOH) prep of the skin scraping reveals a "spaghetti and meatballs"
appearance. What is the appropriate treatment?
A) Oral griseofulvin
B) Topical acyclovir
C) Topical selenium sulfide
D) Oral amoxicillin
Rationale: Tinea versicolor is a superficial fungal infection caused by Malassezia globosa. The
KOH prep finding of short hyphae and round yeast cells mimics a "spaghetti and meatballs"
pattern. First-line treatment involves topical antifungal agents or topical selenium sulfide
2.5% lotion. Acyclovir treats viruses, amoxicillin treats bacteria, and oral griseofulvin is
reserved for tinea capitis.
Question 8
A 5-year-old child presents with honey-colored crusted lesions around the nose and mouth.
What is the first-line treatment for this localized infection?
A) Topical mupirocin
B) Oral amoxicillin
C) Topical hydrocortisone
D) Oral doxycycline
