To identify the described lesion, let's consider the provided options and determine which characteristics align with each type:
Becker nevus: This is a common pigmented skin lesion, usually presenting as a unilateral, hyperpigmented patch with associated hair growth. It often appears during adolescence and has irregular borders but remains benign.
Hypopigmented macule: This refers to a lighter area of skin compared to the surrounding tissue. It can be associated with conditions such as vitiligo or post-inflammatory hypopigmentation.
Spitz nevus: A benign melanocytic lesion, often pinkish and dome-shaped, typically appearing in children and young adults. It may mimic melanoma but is usually benign.
Epidermal nevus: Characterized by a hyperpigmented, raised lesion, often linear, following Blaschko's lines. It's present from birth or early childhood.
Based on these descriptions, the lesion in question aligns most closely with the characteristics of a Becker nevus, given its presentation as a hyperpigmented patch that may have hair growth and appears during adolescence. Thus, the correct answer is Becker nevus.
