Final answer:
Deep plexus disease often shows more severe symptoms including large purpura, redness, warmth, and pain due to the involvement of deeper skin layers, with conditions such as cellulitis, erysipelas and erythema nodosum impacting the dermis and hypodermis, and systemic lupus erythematosus causing widespread inflammation.
Step-by-step explanation:
The characteristic of deep plexus disease, which refers to conditions affecting the deeper vascular networks within the skin, usually manifests as more severe symptoms compared to diseases of the more superficial vascular plexuses. A typical presentation might include larger purpuric or hemorrhagic lesions, which could be associated with a variety of systemic symptoms depending on the specific underlying cause of the vasculitis. For example, when blood leaks from damaged vessels in vasculitis, purple spots called purpura may form. In diseases like cellulitis, erysipelas, and erythema nodosum, which can affect deeper layers of the skin such as the dermis and hypodermis, signs include red, warm, and painful areas on the skin or the development of red nodules, especially on the shins.
It's also important to note the range of skin conditions beyond vasculitis: chickenpox is a common childhood disease with pustular lesions, eczema is an allergic condition presenting with rash, and psoriasis features patches of thick, red skin with silvery scales. Additionally, the systemic condition systemic lupus erythematosus involves a chronic inflammatory response that can affect multiple systems, including the skin.
