In a skin assessment, which lesion should be referred to a dermatologist for further evaluation?

• A. A flat red spot on the forearm
• B. A dark brown-blue lesion with asymmetrical borders between the toes
• C. A raised wart-like growth on the chest
• D. A light brown freckle on the back

Answer: (B)

The dark brown-blue lesion with asymmetrical borders between the toes is the most concerning and warrants referral to a dermatologist for further evaluation. Asymmetrical borders and variations in color are hallmark features of malignant melanoma, a serious form of skin cancer. The location between the toes can also be a common site for atypical skin growths, further emphasizing the need for expert assessment.

Meanwhile, the other lesions presented present less urgent clinical concerns. A flat red spot on the forearm may indicate a benign condition or even a transient skin response, while a raised wart-like growth on the chest is typically linked to benign conditions such as common warts or seborrheic keratosis. Lastly, a light brown freckle on the back, often a common and benign skin feature, usually does not require immediate specialist evaluation unless there are significant changes over time. The identification and referral of potentially malignant lesions are critical in dermatological assessments, where early detection can greatly impact outcomes.
