What skin condition is characterized by burrows and severe itching?

The skin condition characterized by burrows and severe itching is scabies. Scabies is caused by an infestation of the Sarcoptes scabiei mite, which burrows into the skin to lay eggs. This process triggers an intense immune response, leading to severe itching and irritation, particularly at night when the host is at rest. The burrows appear as small, threadlike lines on the skin, and the intense itching can lead to secondary skin infections due to scratching.

In contrast, eczema, psoriasis, and dermatitis can all cause skin irritation and itching, but they do not typically present with burrows. Eczema involves inflammation and often results in dry, red, and itchy patches of skin, while psoriasis is characterized by thick, silvery scales caused by rapid skin cell turnover. Dermatitis is a broad term that refers to inflammation of the skin and can have various causes and manifestations, but none of these conditions involve the burrowing behavior seen in scabies.
