Profuse or extended scabies is characterized by more numerous lesions and the extension of lesions throughout the body. Skin lesions can be found on the back. It is often associated with a late diagnosis, inappropriate treatments, or the presence of an unfavorable immune system, with decreased immunity.
Infantile Scabies
In very young children, scabies can have a deceptive appearance, including facial involvement, scabious nodules around the armpits, and pearl vesicles (small clear fluid blisters) or pustules (small turbid fluid blisters) on the palms of the hands and soles of the feet.

Hyperkeratotic Scabies (or Crusted Scabies)
It occurs in a specific context of immunosuppression (decreased natural defenses, secondary to a disease), or in elderly individuals living in a community setting.
The entire body is affected, including the face, scalp, and nails. There is erythroderma (diffuse redness of the entire body) with hyperkeratotic lesions, meaning that the horny layer of the skin is very thickened with scales and crusts, extensively. Importantly, itching may be absent or moderate.
Much less common than classic scabies, it is an extremely contagious form with thousands of parasites in the skin. Sometimes, hyperkeratotic scabies is limited to a skin segment.

Complicated Scabies
Scabies lesions can be superinfected, especially by staphylococcus (bacteria that secondarily colonizes the skin affected by scabies parasites). This is referred to as impetiginization of the lesions. Eczema can also occur secondary to scabies, particularly in individuals with dry skin and/or intolerance to treatment.
Animal Scabies
There is also animal scabies related to other sarcoptes, including various types such as canine scabies, sheep scabies, etc. These different forms of scabies can be transmitted to humans, who represent a dead-end host (cannot transmit it to another human). Animal scabies also manifests with itching.
