Pyotraumatic dermatitis

From Biology-Online Dictionary | Biology-Online Dictionary



A type of traumatic dermatitis characterized by skin erythema and weeping lesion on skin caused by biting, licking, and scratching of the affected area and worsened by bacterial infection on the lesion


Traumatic dermatitis is a type of dermatitis that is caused by physical agent or an irritant. Pyotraumatic dermatitis is a type of traumatic dermatitis. This is commonly observed in dogs and cats. The condition is characterized by skin itchiness. Dogs and cats tend to incessantly bite, lick, chew, or scratch the affected area. As a result, the skin becomes swollem, erythematous, and damaged. The disruption on the skin causes bacteria to enter and bring about infection. Thus, the lesion becomes worse due to the infection. The lesion forms pus as a result. That is why it is called pyotraumatic. Etymologically, pyo refers to pus. The pus forms as a result of the immune cells that fight off bacterial infection.

Pyotraumatic dermatitis can be problematic to pet owners of dogs and cats. The lesion can be self-inflicted because of the constant biting and scratching of the affected skin. Thus, the affected area may worsen and become larger than it was when it started. Pyotraumatic dermatitis is may be accompanied by hot spots. A hot spot is one in which the lesion is weeping or oozing. The term hot spot is sometimes used interchangeably with pyotraumatic dermatitis.

Word origin: pyo- (pus) + -traumatic + dermatitis
