What type of skin condition is characterized by crusted pustules?

Impetigo is a highly contagious bacterial skin infection that is characterized by the development of crusted pustules. These pustules typically appear as red sores on the face, especially around the nose and mouth, which can rupture and ooze, forming a yellow-brown crust. The condition is often more prevalent in young children but can affect individuals of all ages.

The presence of pustules and crusting is a key diagnostic feature of impetigo, distinguishing it from other skin conditions. For example, eczema is associated with itchy, inflamed skin that does not primarily present with pustules, while psoriasis is known for its raised, scaly patches rather than crusted pustules. Dermatomycosis, commonly known as a fungal infection of the skin, typically presents with different symptoms, such as red, itchy, and scaly areas without the pustular crusting seen in impetigo.
