PSI Barbering Practice Exam

Which of the following are irregularly shaped dark spots sometimes found on the scalp and ears, often first detected by a barber?

1. Basal cell carcinomas

2. Moles

3. Melanomas

4. Warts

The correct answer is: Melanomas

Melanomas are a type of skin cancer that can present as irregularly shaped dark spots on the scalp and ears. These spots are often characterized by asymmetry, uneven borders, multiple colors, and a larger diameter than typical moles. Barbers, being in close proximity to clients' scalps and ears, are often the first to notice these changes, which is important for early detection. In contrast, basal cell carcinomas usually appear as pearly or waxy lesions, not necessarily as dark spots. Moles, while they can be dark, are typically symmetrical and uniform in color. Warts are caused by viral infections and typically have a different texture and appearance, often resembling small, rough bumps rather than dark spots. Thus, the description of "irregularly shaped dark spots" aligns closely with the characteristics of melanomas.
