Skin examination is a fundamental aspect of dermatology clinic visits. Although there are guidelines for assessing lesions with the naked eye, this approach often leads to increased biopsies for benign lesions. Dermatoscopy, or dermoscopy, is a crucial tool in dermatology, which helps clinicians evaluate dermatologic lesions and enhances the accuracy of distinguishing between benign and malignant skin lesions. This noninvasive technique, which includes polarized light for visualizing deeper skin structures, correlates well with histopathological findings, aiding in more accurate clinical assessments. Dermoscopy improves diagnostic precision and enables healthcare providers to assess lesions more accurately for malignancy, thereby reducing unnecessary biopsies, enhancing the decision-making process, and aiding in the identification of melanomas and nonmelanoma skin cancers, including various basal cell carcinoma subtypes. This activity explores the clinical significance of dermoscopy and key dermoscopic characteristics in distinguishing between benign and malignant skin lesions. This activity also helps clinicians better understand dermoscopic findings and more confidently identify the characteristics of dermatologic lesions. In addition, this activity emphasizes the importance of integrating dermoscopy into clinical practice and highlights the role of the interprofessional healthcare team in enhancing care through advanced diagnostic capabilities. This activity demonstrates how refining biopsy decision-making and optimizing treatment strategies through improved dermoscopic proficiency among clinicians leads to better patient outcomes. Objectives: Identify dermatoscopic characteristics that distinguish melanoma from benign lesions and nonmelanoma cancers, including specific patterns such as irregular globules and blue-gray veils. Implement dermoscopic techniques effectively to reduce unnecessary biopsies and improve patient outcomes by using polarized light to visualize deeper skin structures. Apply knowledge of dermatoscopic patterns and criteria, such as the BRAAFF checklist, to evaluate acral lesions and determine the likelihood of malignancy. Collaborate with the interprofessional healthcare team to ensure comprehensive care and follow-up for patients with suspected skin cancers, integrating dermoscopy into the diagnostic workflow.

Dermoscopy, also known as dermatoscopy, is a valuable noninvasive handheld tool that enables clinicians to examine skin lesions under microscopic magnification. An additional feature, polarized light, enhances the visualization of deeper skin structures.[1] Studies have demonstrated that this instrument reduces costs by decreasing the number of biopsies compared to evaluations based solely on the naked eye.[2] Dermoscopic characteristics often correlate with histopathologic findings, providing clinicians with deeper insights into the nature of the lesions being examined.[3] While a naked eye examination can be useful, it has been observed that up to 40% of melanomas may be misclassified when clinicians rely solely on the ABCDE rule.[4] The ABCDE rule includes asymmetry, border irregularity, color variegation, diameter greater than 6 mm, and evolution.[5] Dermoscopy not only aids in diagnosing melanomas but is also valuable in identifying nonmelanoma skin cancers. Studies have shown that dermoscopy can help differentiate among various subtypes of basal cell carcinomas.[6] This is significant as the various histological subtypes of basal cell carcinomas require distinct treatment approaches.[6]

Dermoscopy is an invaluable tool for clinicians performing thorough skin examinations. Enhancing patient-centered care, outcomes, safety, and team performance related to dermoscopy requires an interprofessional approach involving physicians, advanced practitioners, nurses, pharmacists, and other healthcare professionals. Physicians must master dermoscopic techniques to accurately distinguish between benign and malignant lesions, guiding diagnostic decisions and treatment planning. Proper training is essential for correctly identifying the characteristics of various skin lesions under dermoscopy. Dermoscopy significantly increases specificity in differentiating benign pigmented lesions from melanoma. Although the benefits of diagnosing nonmelanoma skin cancers are slightly lower, these lesions still exhibit distinguishing dermoscopic features that aid their diagnosis. Advanced practitioners and nurses must develop proficiency in recognizing dermoscopic patterns and assisting with the examination process. They are also crucial in patient education and support during follow-up care. Pharmacists are essential in understanding dermoscopic procedures and offering relevant medication advice, particularly for post-biopsy care and treatment. An interprofessional approach is crucial for implementing evidence-based protocols for dermoscopic examinations, ensuring standardized care, and developing clear follow-up strategies for patients with identified lesions to guarantee timely management and intervention. Using checklists such as the BRAAFF algorithm for acral melanoma can significantly improve diagnostic accuracy when distinguishing malignant from benign lesions.[17][18] Interprofessional healthcare teams can enhance the efficacy of dermoscopy in clinical practice through coordinated care efforts. This includes efficiently referring patients to oncologists when advanced care is necessary and educating patients about their skin health, the importance of follow-ups, and preventive measures.

Interprofessional healthcare teams can enhance the efficacy of dermoscopy in clinical practice through coordinated care efforts. This includes efficiently referring patients to oncologists when advanced care is necessary and educating patients about their skin health, the importance of follow-ups, and preventive measures. Studies demonstrate that dermoscopy can be cost-effective by reducing unnecessary biopsies, lowering healthcare costs, and decreasing patient anxiety associated with unnecessary procedures. Fewer biopsies also result in fewer scars, thereby improving patient satisfaction. Encouraging physicians to use dermoscopy benefits both patients and the healthcare system. Strategizing dermoscopy use ensures diagnostic accuracy and optimizes patient outcomes.
