Your Guide to Better Skin Exams
Your Weekly Prompt to the Science of Skin and Success.

Welcome back and Happy New Year, DERM Community!
In our latest issue, Dr. Kent, our editor and founder, shared some valuable advice: one of the most essential skills you can develop early in your dermatology practice is the ability to perform a detailed and accurate physical exam. This means more than just looking at the skin—it’s about identifying primary and secondary lesions, spotting disease patterns, and understanding the timeline of how conditions present.
At Derm for Primary Care, we’re dedicated to helping providers like you refine these skills. Our CE courses are designed to ensure you feel confident diagnosing and managing the majority of skin conditions that come your way.
This week, we’re kicking off a two-part series focused on the physical exam and dermatologic diagnosis. Think of it as your guide to starting the year on the right foot. With practical insights and tips, we’ll help you sharpen your approach to patient care. And next week, we’ll build on this with even more strategies to set you up for success.

🚀 Learning Opportunities: Physical Exam & Dermatologic Diagnosis

Getting Back to Basics: Why Dermatologic Diagnosis Is Unique
Dermatology is often a visual puzzle—and it’s one that many non-dermatologists find tricky. Why? Because most medical training doesn’t prioritize the visual skills needed to excel in this field.
We’re taught that patient history is king, but when it comes to dermatologic care, the physical exam is where the magic happens. Of course, history is still important—it can even be critical—but it’s hard to know the right questions to ask if you don’t understand what you’re seeing.
Understanding dermatologic diagnosis and physical examination is essential for managing common skin problems in primary care practice. Here’s a guide to help you build confidence in identifying and addressing skin conditions effectively.
You’ll learn about:

Physical Exam: The Cornerstone of Dermatology
A systematic approach is the foundation of successful dermatologic care. Conduct every skin exam with the same methodical precision to ensure consistency and thoroughness.
New Patient Evaluation: Whenever possible, assess as much of the patient’s skin as is appropriate, especially if there is a personal or family history of skin cancer. For high-risk patients, consider using a gown to facilitate a more comprehensive evaluation.
Focus on Overlooked Areas: The scalp and oral cavity are often under-examined but can reveal critical findings.
Thorough, Not Rushed: A complete total body skin exam takes just three to four minutes—time well spent for a thorough evaluation. One should standardize their exam and perform it in the same sequence every time so not to miss key exam findings.
Engage the Patient: Encourage patients to confirm lesion locations with a mirror and discuss any changes, such as size or shape, since their last visit.
Enhance Your Tools: Proper lighting, magnification, and palpation are indispensable for assessing texture, consistency, tenderness, or induration.
Elevate your diagnostic accuracy by integrating these practices into every patient encounter. It’s the small details that lead to significant insights.
Key Elements of Dermatologic Diagnosis
Distribution of Lesions
The location of lesions can often direct the diagnosis. Pay attention to specific patterns:
Bilateral vs. Unilateral: Symmetrical or asymmetrical involvement.
Sun-Exposed Areas: Face, ears, neck, and extremities.
Flexural vs. Extensor Areas: Bending areas (e.g., wrists, ankles) versus exposed surfaces (e.g., arms, legs).
Dermatomal Patterns: Follows specific nerve root distributions.
—————
Morphological Appearance
Morphology is critical for diagnosis:
Primary Lesions: Identify macules, plaques, papules, nodules, vesicles, pustules, and more.
Assess Changes: Ask about size, shape, and interval changes in lesions.
—————
Common Descriptors for Lesions
Flat-Topped Papules: Characteristic of lichen planus.
Umbilicated Lesions: Central depression, seen in molluscum contagiosum.
Verrucous Lesions: Warty appearance, often seen in verruca vulgaris.
Always Remember: A complete skin examination at the initial visit is strongly recommended and ensures no critical findings are missed. Always have a chaperone present when necessary.
Examples of Primary Lesions

Lesion Type | Description | Examples |
Macule | Flat, non-palpable area | Vitiligo |
Papule | Elevated bump ≤ 1 cm | Lichen planus, acne |
Plaque | Palpable, elevated lesion > 1 cm | Psoriasis, eczema |
Nodule | Solid lesion, 0.5–2 cm | Dermatofibroma |
Vesicle | Fluid-filled lesion < 0.5 cm | Herpes simplex, chickenpox |
Pustule | Vesicle with pus | Acne, impetigo |
Bullae | Fluid-filled lesion > 0.5 cm | Bullous pemphigoid |
Cyst | Fluid or debris in a sac | Sebaceous cyst |
Telangiectasia | Visible dilated blood vessels | Rosacea, spider angioma |
What Every Clinician Should Remember
Mastering dermatologic diagnosis begins with meticulous visual examination and recognition of key morphological and distribution patterns. With practice, these skills can dramatically enhance your ability to provide accurate and effective care for skin-related issues in primary care.
Start with a systematic approach: Perform the physical exam the same way with every patient to avoid missing key findings.
Lighting and tools matter: Adequate lighting, magnification, and palpation improve accuracy in identifying lesions.
Distribution tells a story: Pay close attention to lesion locations; they often provide critical diagnostic clues.
Primary lesions are diagnostic anchors: Recognizing primary lesions (macules, papules, nodules, etc.) is essential for accurate diagnoses.
Complete exams count: Whenever appropriate, perform a total body skin exam, especially for patients with a personal or family history of skin cancer.
Ask informed questions: Use physical findings to guide history-taking and uncover crucial details about the patient's condition.
Dermatology is visual first: Unlike many other fields, successful dermatologic diagnoses heavily rely on what you see—so train your eyes!
