Dermatosis is a general term encompassing any skin defect or lesion. It's an umbrella term covering a wide range of skin conditions, and may also involve the hair and nails. This means it describes any irregularity or abnormality in the skin's appearance or function.
Types and Causes of Dermatoses
Several skin conditions fall under the dermatosis category. The causes are varied and can include:
- Autoimmune disorders: Where the body's immune system attacks its own tissues, leading to skin conditions.
- Genetic factors: Some dermatoses have a hereditary component.
- Infections: Bacterial, viral, or fungal infections can cause skin lesions.
- Environmental factors: Exposure to irritants or allergens can trigger dermatoses.
Examples of specific dermatoses include:
- Dermatomyositis: A systemic disease affecting both skin and muscles.
- Dermatosis papulosa nigra (DPN): Benign, small, dark-colored growths typically found on the face and neck. These are harmless and don't cause ulcerations, scaling, or other complications.
Systemic vs. Localized Dermatoses
The term "systemic dermatosis" indicates that the condition affects the entire body, not just a localized area. This implies a connection to problems in other organs. Conversely, many dermatoses are localized to specific areas of the skin.
