Which of the following statements about sarcoidosis is NOT true?

Sarcoidosis is indeed an idiopathic condition, mostly affecting individuals without a clear reason, which supports the correctness of that statement. The disease is known to impact various demographics, but there are more nuanced details regarding the prevalence among different ethnic groups and genders.

It is recognized that sarcoidosis has a higher prevalence in certain demographics, particularly African Americans, compared to Caucasians. While it is true that sarcoidosis can affect Caucasians, stating that it primarily affects them lacks accuracy, as studies have shown a higher incidence in African American populations. This context clarifies why the assertion regarding its primary impact on Caucasians is not true.

As for the other statements, sarcoidosis does affect middle-aged females more than males, which aligns with epidemiological patterns. Furthermore, the elevated levels of angiotensin-converting enzyme (ACE) along with chest X-rays are indeed useful diagnostic tools often utilized in the evaluation of sarcoidosis, confirming their validity in the diagnostic process.
