A form of dermatitis that is caused by a physical agent or an irritant
Dermatitis is a condition pertaining to the inflammation of the skin and is characterized by itchiness, redness, and weeping, crusting patches on skin. There are various types of dermatitis. Perhaps, the most common type is the eczema, which is also known as atopic dermatitis. Other types of dermatitis include traumatic dermatitis, dermatitis venenata, dermatitis factitia, dermatitis medicamentosa, dermatitis gangrenosa, and so on. 1
Traumatic dermatitis pertains to a type of dermatitis in which a local trauma occurs on skin that may be caused by a physical agent or an irritant such as pressure, friction, blow, etc. The trauma may range from a temporary redness on skin to severe lesions extending to deep tissues (e.g. bed sores). An example of traumatic dermatitis is the pyotraumatic dermatitis also referred to as hot spots such as one that occurs in dogs and cats. Pyotraumatic dermatitis is a superficial skin lesion that typically becomes infected by bacteria that gained entry from the damaged skin surface. It is itchy and painful that causes dogs and cats to bite, lick or scratch the affected area, thereby, worsening the condition.
