Which of the following is NOT a characteristic of psoriasis?

The characteristic of psoriasis that is not true is the presence of non-inflammatory red bumps. Psoriasis is an autoimmune condition that leads to the overproduction of skin cells and manifests primarily as red patches covered with silver-white scales. These patches are typically inflammatory and can be quite raised, which is distinct from non-inflammatory skin conditions.

In psoriasis, the red patches indicate inflammation and can be accompanied by a lot of irritation and itchiness, making options that mention these elements accurate representations of the condition. Non-inflammatory red bumps do not fit the typical presentation of psoriasis, as the condition's features are specifically associated with inflammation and scaling. This distinction is crucial for understanding and identifying psoriasis effectively.
