What type of melanoma typically occurs in younger patients and has irregular borders?

• A. Superficial spreading melanoma
• B. Nodular melanoma
• C. Acral lentiginous melanoma
• D. Lentigo maligna melanoma

Answer: (A)

Superficial spreading melanoma is the type of melanoma that most commonly occurs in younger patients and is characterized by its irregular borders. This subtype often presents as a flat or slightly elevated discolored area on the skin, which can change in color, size, and shape. The irregular borders are a hallmark feature, making it a distinguishing characteristic of this melanoma type.

This form of melanoma is particularly relevant in discussions about skin cancer as it is one of the most prevalent types among younger individuals. The early detection of superficial spreading melanoma is crucial because it is more amenable to treatment when caught in its initial stages compared to other forms of melanoma.

In contrast, other types of melanoma, such as nodular melanoma, typically present at later ages and often exhibit more vertical growth patterns without the same irregularities in shape as seen in superficial spreading melanoma. Acral lentiginous melanoma, while it can occur in all ages, is more common in individuals with darker skin and tends to occur in areas not typically exposed to the sun, such as the palms and soles. Lentigo maligna melanoma typically arises in older individuals and is associated with sun-damaged skin, particularly in the face and neck area.

Understanding the characteristics of these various melanoma types is essential for early
