shows darkened and thickened skin on the neck, characteristic of acanthosis nigricans. This condition is commonly associated with:
1.Insulin resistance: Often seen in prediabetes, type 2 diabetes, or obesity.
2.Endocrine disorders: Such as polycystic ovary syndrome (PCOS).
3.Certain medications: Like corticosteroids or contraceptives.
4.Rare malignancies: Particularly in older adults (less common).

Recommendations:
1.Medical consultation: Especially with an endocrinologist to assess for insulin resistance or metabolic issues.
2.Suggested tests:
•Fasting glucose and glucose tolerance test.
•Fasting insulin and insulin curve.
•Lipid profile.
3.Treatment: Addressing the underlying cause (e.g., glucose or weight management) often improves the skin condition.
