Which of the following describes a macule?
A flat, discolored spot on the skin
A fluid-filled lesion
A thickened scar
A raised, solid bump
A macule is a flat spot on the skin that is only a color change without elevation or depression. It measures less than 1 centimeter in diameter and includes freckles and flat moles. Recognition of macules is fundamental in skin disorder assessment.
What is a papule?
A small, raised, solid bump less than 1 cm
A fluid-filled blister
A flat discoloration
A crusted lesion
Papules are small, raised, solid lesions that are less than 1 centimeter in diameter. They can be felt when touched and are common in conditions like dermatitis. Identifying papules helps distinguish them from vesicles or macules.
Which lesion is characterized as a pustule?
A raised, pus-filled lesion
A flat patch of pigment
A deep ulcer
A thick, scaly area
Pustules are elevated lesions filled with pus, often seen in acne and infections. They are distinguished from vesicles by their turbid fluid content. Proper recognition guides appropriate treatment, such as antiseptics or antibiotics.
Milia are best described as:
Clusters of hyperpigmented spots
Large fluid-filled blisters
Tiny, white epidermal cysts
Red, scaling patches
Milia are small, keratin-filled cysts that appear as white bumps, commonly around the eyes. They form when dead skin cells become trapped in pockets at the skin's surface. Extraction by a professional can remove them safely.
A crust on the skin is formed by:
Accumulation of dead keratin cells
Thickening of the dermis
Epidermal fluid accumulation
Dried blood, serum, or pus
Crusts result when exudate such as blood, serum, or pus dries on the skin surface. They are often referred to as scabs and indicate healing or ongoing lesions. Proper cleansing helps prevent secondary infection.
What is the primary characteristic of a scale?
Blood-filled blister
Flaky accumulation of excess keratin
Deep skin ulceration
Firm, raised papule
Scales are flakes or plates resulting from an accumulation of excess keratin cells. They are common in conditions like psoriasis and eczema. Identifying scales helps guide exfoliation treatments.
A fissure is defined as:
A small solid elevation
A flat discoloration
A linear crack in the skin
A fluid-filled blister
Fissures are cracks or splits in the skin often seen in dry or chapped areas. They can be painful and may bleed if deep. Moisturizing and protecting against friction can improve healing.
An ulcer is characterized by:
Small white cyst
Superficial dry scales
Raised solid bump
A deeper loss of skin surface, possibly bleeding
Ulcers are deep lesions that penetrate the epidermis and possibly the dermis, often resulting in bleeding or scarring. They may result from pressure, infection, or impaired circulation. Proper wound care and infection control are critical.
Which lesion is larger than a macule and is flat?
Nodule
Pustule
Patch
Papule
Patches are flat, nonpalpable discolorations greater than 1 centimeter in diameter. They differ from macules solely by size. Common examples include port-wine stains and vitiligo lesions.
A scar forms as a result of:
Accumulation of sebum
Subcutaneous fat loss
Lag of melanin production
Fibrous tissue replacing damaged skin
Scars develop when fibroblasts produce collagen to repair a wound, replacing normal skin tissue with fibrous connective tissue. The result can be raised, depressed, or pigmented depending on the healing process. Proper wound care can minimize scar formation.
Which of the following is a secondary lesion?
Vesicle
Macule
Papule
Ulcer
Secondary lesions result from the alteration or progression of primary lesions. Ulcers, which are deep losses of skin surface, are classified as secondary. Recognizing secondary lesions is important for accurate diagnosis.
Which condition is characterized by red, itchy, scaly patches?
Eczema
Milia
Rosacea
Vitiligo
Eczema, or atopic dermatitis, presents with inflamed, red, scaly, and itchy patches on the skin. It often has a chronic or relapsing course. Treatment focuses on hydration and topical anti-inflammatories.
Psoriasis commonly produces which lesion?
Flat hypopigmented spots
Thick, silvery scales on red plaques
Small white cysts
Fluid-filled pustules on palms
Psoriasis is marked by well-demarcated, red plaques covered with thick, silvery scales, often on elbows and knees. These scales result from rapid epidermal turnover. Management may include topical therapies, phototherapy, or systemic agents.
Comedones in acne are classified as:
Primary lesions
Tertiary lesions
Non-lesional changes
Secondary lesions
Comedones, either open (blackheads) or closed (whiteheads), are primary lesions of acne vulgaris. They form when follicular openings become clogged with sebum and dead cells. Recognizing them is essential for acne treatment strategies.
Melasma appears as:
Thick, yellow crusts
Symmetric hyperpigmented patches on the face
White, depigmented spots
Vesicles around the mouth
Melasma presents with symmetric brown to gray-brown patches on sun-exposed areas of the face, often linked to hormonal changes. UV exposure exacerbates the pigmentation. Treatment includes sun protection and topical lightening agents.
A keloid scar is different from a hypertrophic scar because keloids:
Remain within wound boundaries
Are flat and hypopigmented
Extend beyond the original wound margins
Contain fluid-filled vesicles
Keloids grow beyond the original wound site due to excessive collagen deposition. Hypertrophic scars stay within the wound boundaries but may be raised. Distinguishing them guides treatment decisions like corticosteroid injections.
What is leukoderma?
Inflammation with scaling
Excess melanin causing dark patches
Loss of pigmentation resulting in white patches
Clear fluid-filled blisters
Leukoderma describes localized depigmentation of the skin, resulting in white or lighter-colored patches. Vitiligo is a common form. The condition arises from melanocyte destruction or dysfunction.
Which disorder is characterized by hypopigmented, scaly patches on the trunk?
Milia
Rosacea
Tinea versicolor
Impetigo
Tinea versicolor, caused by Malassezia yeast, produces small, hypopigmented or hyperpigmented scaly patches on the trunk. It often worsens in warm, humid conditions. Antifungal shampoos or creams are effective treatments.
Leukoplakia in the mouth refers to:
White, thickened patches potentially precancerous
Ulcerated lesions
Red, inflamed areas
Fluid-filled blisters
Leukoplakia presents as white, thickened patches on mucous membranes, often in the mouth. It can be precancerous, requiring biopsy for diagnosis. Tobacco and alcohol use are common risk factors.
Propionibacterium acnes contributes to acne by:
Breaking down collagen in the dermis
Causing epidermal thickening
Inducing inflammation in clogged follicles
Producing hyperpigmentation
Propionibacterium acnes (now Cutibacterium acnes) thrives in sebum-rich follicles, releasing inflammatory mediators. This inflammation contributes to the redness and swelling of acne lesions. Antibacterial treatments aim to reduce its population.
Contact dermatitis produces which primary lesion when acute?
Keloids
Vesicles
Papules
Pustules
Acute contact dermatitis often presents with vesicles - small, fluid-filled blisters - due to an allergic or irritant response. Ruptured vesicles can lead to crusting. Avoiding triggers and topical steroids help manage symptoms.
Seborrheic keratosis is best described as:
Benign, waxy, 'stuck-on' epidermal growths
Deep dermal cysts
Malignant melanocyte tumors
Pus-filled nodules
Seborrheic keratoses are benign epidermal lesions that appear as waxy, wart-like growths. They often develop with age and have a 'pasted on' look. No treatment is needed unless for cosmetic reasons.
Herpes simplex virus type 1 commonly causes:
Warts on hands
Tinea pedis
Chickenpox
Oral cold sores
Herpes simplex virus type 1 (HSV-1) typically causes recurrent oral cold sores or fever blisters. The virus remains dormant in nerve ganglia and reactivates with stress or UV exposure. Antiviral medications can reduce outbreak frequency.
Actinic keratosis is a concern because it:
Causes hypopigmentation
Forms deep dermal cysts
Is highly contagious
May progress to squamous cell carcinoma
Actinic keratoses are precancerous lesions caused by chronic UV exposure, appearing as rough, scaly patches. They carry a risk of transforming into squamous cell carcinoma. Early detection and treatment, such as cryotherapy, reduce this risk.
Impetigo typically presents with:
White pustules on palms
Purple bruising
Honey-colored crusts
Linear cracks
Impetigo is a superficial bacterial infection often characterized by honey-colored crusts around the nose and mouth. It is most commonly caused by Staphylococcus aureus or Streptococcus pyogenes. Antibiotic ointments or oral antibiotics are used for treatment.
Rosacea is distinguished by:
Vesicles on the trunk
Chronic central facial erythema with telangiectasia
Nodular cysts on limbs
Patchy hypopigmentation
Rosacea presents with persistent redness, flushing, and visible blood vessels on the central face. Papules and pustules may also develop, but comedones are absent. Management includes topical and oral therapies plus sun protection.
Telangiectasia refers to:
Thick, keratinized scales
Deep dermal cysts
Small fluid-filled blisters
Dilated superficial blood vessels
Telangiectasia are small, dilated blood vessels visible near the skin surface, appearing as red lines or patterns. They can occur in rosacea, basal cell carcinoma, or long-term sun damage. Laser or vascular treatments can minimize their appearance.
Dermatitis medicamentosa is caused by:
Vitamin deficiency
Fungal infection
Bacterial colonization
Adverse drug reactions on the skin
Dermatitis medicamentosa is an allergic or irritant reaction of the skin to medications, presenting with rashes or urticaria. Identifying the offending drug and discontinuing it is essential. Topical or systemic corticosteroids may be prescribed.
A 45-year-old woman presents with symmetric, blotchy hyperpigmentation on her cheeks after pregnancy. What is the most likely diagnosis?
Post-inflammatory hyperpigmentation
Vitiligo
Melasma
Tinea versicolor
Melasma commonly affects women, especially during pregnancy or with oral contraceptive use, presenting as symmetric hyperpigmented patches on the face. It is often called the 'mask of pregnancy.' Management includes strict sun protection and topical lightening agents.
In vitiligo, the mechanism of depigmentation is:
Overgrowth of keratinocytes
Excess sebum production
Autoimmune destruction of melanocytes
Fungal colonization
Vitiligo results from autoimmune targeting and destruction of melanocytes, leading to well-demarcated depigmented macules. Genetic and environmental factors contribute to its development. Treatments include topical immunomodulators and phototherapy.
A rapidly enlarging pigmented lesion with irregular borders on sun-exposed skin should raise concern for:
Actinic keratosis
Malignant melanoma
Seborrheic keratosis
Basal cell carcinoma
Malignant melanoma often presents as a new or changing pigmented lesion with asymmetry, border irregularity, color variation, and diameter enlargement. Early detection and biopsy are critical for prognosis. Sun protection reduces melanoma risk.

Cheat Sheet

  1. Understanding Primary and Secondary Lesions -

    Primary lesions appear on previously unaltered skin - common examples include papules, vesicles, and pustules - while secondary lesions, such as crusts, scales, and scars, arise from the evolution or external manipulation of primary lesions. A simple mnemonic is "Primary Pops, Secondary Sequel" to track lesion progression. This classification is essential for the Milady Chapter 8 Test on skin disorders and diseases, ensuring you differentiate lesions confidently (Source: American Academy of Dermatology).

  2. Characteristics of Milia -

    Milia are tiny, 1 - 2 mm white keratin-filled cysts that often dot the cheeks and under the eyes, appearing as "milk spots" in newborns and adults alike. They stem from trapped keratin under the skin's surface and require gentle exfoliation or professional extraction. The phrase "Milia Milk" can help you recall their signature appearance and benign nature (Source: NIH Dermatology Library).

  3. Flat Discolorations - Macules vs. Patches -

    Flat lesions are called macules if they're under 1 cm (like freckles) and patches if they're larger (such as port-wine stains). Despite varying colors - from brown to wine-red - their classification hinges solely on size and flatness, not hue. This rule, emphasized by dermatology texts at Johns Hopkins, is a must-know for the Milady Chapter 8 test.

  4. Identifying Fissures -

    Fissures are linear cracks extending into the dermis, commonly seen in conditions like angular cheilitis or athlete's foot, and they often bleed or sting. Keeping skin hydrated with emollients and applying barrier creams can prevent infection and promote healing. The Mayo Clinic highlights proper moisturization as key to managing these painful breaks.

  5. Pigmentary Disorders: Melasma (Chloasma) -

    Melasma, often dubbed the "mask of pregnancy," manifests as brownish patches on sun-exposed areas and is triggered by UV radiation and hormonal changes. A quick mnemonic - "MELASMA = Mothers Exposed to Light And Solar Melanin Amplified" - can help you remember its etiology. The American Society for Dermatologic Surgery notes that strict sun protection is crucial for both prevention and treatment.
