## **Why Each Wrong Option is Incorrect**
* **Option A:** This option is incorrect because while it might seem plausible, there's no direct association with adenoma sebaceum that is widely recognized in medical literature.
* **Option B:** This option is incorrect as it does not directly relate to the characteristic skin manifestations of tuberous sclerosis complex.
* **Option C:** This option is incorrect because, although certain skin conditions are associated with systemic diseases, adenoma sebaceum is specifically linked to tuberous sclerosis complex.

## **Clinical Pearl / High-Yield Fact**
A key clinical pearl is that adenoma sebaceum is one of the major diagnostic criteria for tuberous sclerosis complex. The presence of these lesions, along with other criteria such as cardiac rhabdomyomas, renal angiomyolipomas, and tubers in the brain, helps in the diagnosis of TSC.
