Which symptom is NOT associated with Cushing's syndrome?

Cushing's syndrome is characterized by excessive cortisol levels in the body, leading to a constellation of specific symptoms that arise from cortisol's effects on various tissues. Recognizing the hallmark symptoms is key to understanding the condition.

Moon facies, which is the rounded, plethoric appearance of the face, and buffalo hump, which describes the accumulation of fat on the upper back and neck, are both classic manifestations of Cushing's syndrome. Hypertrichosis, or increased hair growth, can also occur due to elevated cortisol levels. These symptoms stem from the changes in fat distribution and skin properties caused by prolonged high cortisol.

Corneal opacity, however, is not a symptom associated with Cushing's syndrome. This condition typically results from different etiologies such as infections, degenerative diseases, or other systemic disorders, rather than being directly influenced by the hormonal imbalances seen in Cushing's syndrome. Therefore, recognizing the unique symptoms of the syndrome helps differentiate it from other conditions that do not share the same hormonal pathways.
