Which histological subtype of cutaneous malignant melanoma is the MOST common in fair-skinned populations?
- A Superficial spreading melanoma ✓
- B Nodular melanoma
- C Lentigo maligna melanoma
- D Acral lentiginous melanoma
Correct answer: A. Superficial spreading melanoma
Explanation
Superficial spreading melanoma accounts for roughly 70 percent of cutaneous melanomas in Caucasians and typically arises in intermittently sun-exposed skin of the trunk in men and legs in women. Nodular melanoma is the second commonest and lacks a radial growth phase. Acral lentiginous melanoma is the commonest subtype in darkly pigmented races, not in fair-skinned populations.
