Step 1: Understanding Cushing's syndrome.
Cushing's syndrome is caused by prolonged exposure to high levels of cortisol. The typical signs include redistribution of body fat, leading to a round "moon face," accumulation of fat on the upper back known as "buffalo hump," and a pendulous (hanging) abdomen.
Step 2: Analysis of other options.
- (1) Muscle weakness, fatigue, dry skin: These are nonspecific symptoms and do not distinctly identify Cushing's syndrome.
- (3) Puffy face, dry skin, enlarged eyes: Puffy face may occur in other conditions, and enlarged eyes are not a feature of Cushing's.
- (4) Weight loss, intolerance to cold, fatigue: These are more characteristic of hypothyroidism, not Cushing's syndrome.
Step 3: Conclusion.
The characteristic symptoms of Cushing's syndrome are correctly represented by option (2).
