Final answer:

DDx stands for differential diagnosis, a process that helps to identify the disease causing a patient's symptoms. It involves comparing and contrasting possible conditions, as seen with skin issues like contact dermatitis and xeroderma pigmentosa. Understanding the array of skin conditions and their healing is essential in dermatology.

Step-by-step explanation:

The term 'DDx' in the context of diseases and disorders of the skin refers to 'differential diagnosis.' This is a systematic method used by physicians and healthcare professionals to identify a disease or condition that could cause a patient's symptoms.

The process involves considering the various possible conditions that might produce the symptoms and systematically differentiating between them, often through the analysis of medical history, physical examination, and diagnostic tests. For example, skin responses like contact dermatitis and a tuberculin reaction could have dermatological symptoms that overlap with other conditions, so it is important to perform a DDx to accurately diagnose the issue. In the case of xeroderma pigmentosa, this is a condition in which DNA damage from exposure to UV light is not effectively repaired, leading to skin lesions, highlighting the necessity for accurate differential diagnosis in skin disorders.

Injuries to the skin, such as burns or cuts, will trigger a healing process that can include inflammation, the formation of new tissue and, at times, scarring. Understanding the various skin conditions, diseases, and disorders, as well as their healing processes, is crucial in dermatology.
