Skin rashes that develop on small sections of your body are usually caused by an external skin problem, such as an allergic reaction to a substance or material, localized skin inflammation or skin disease. Full body rashes, however, can often signal the presence of an internal problem. There are four main causes of body rashes:digestive system disorders, drug reactions, certain cancers and thyroid problems.

Digestive System Disorders:
A number of digestive system problems can cause rashes to develop across the body. These disorders include celiac disease, liver disease, anemia related to iron deficiency and kidney problems.
Celiac disease is a disorder in which an individual's intestinal tract cannot absorb gluten protein from foods such as wheat, rye or barley. The immune system treats gluten as a dangerous foreign body and reacts by destroying the villi lining the intestines. The destruction of the villi causes the person to become deficient in certain nutrients, and to experience symptoms such as seizures, fatigue and a characteristic itchy rash covering the body.
Both liver and kidney problems can cause body rashes since both of these organs are responsible for filtering toxic substances from the bloodstream. If either aren't working properly, the substances can build up and cause persistent outbreaks across the body.
Iron deficiency anemia develops when the body has too few circulating red blood cells because of a lack of available iron. Again, the rash that can occur with this condition is thought to be due to a buildup of substances that the immune system reacts to.

Drug Reactions:
There are a number of commonly prescribed medications that can cause allergic reactions that result in widespread rashes. These medications include both ingested and topical antifungal drugs, such as fluconazole, ketoconazole or clotrimazole; antibiotics like penicillin or cephalosporins; and certain pain medications such as any oxycodone drugs or duloxetine. Chemotherapy drugs may also cause body rash.

Immune System Cancers:
Cancers that affect the immune system, particularly leukemia and lymphoma, can cause body rashes. Individuals suffering from leukemia often have small red, rash-like spots on their skin caused by blood leaking from the capillaries that lie just under the skin. People with lymphoma do not develop these spots, but can suffer from extremely itchy, red skin.

Thyroid Disorders:
A thyroid gland that produces too much of the thyroid hormone can lead to a condition known as Graves' dermopathy -- a widespread, lumpy skin rash. Similar to many of the other causes of rashes, this usually develops with the immune system attacks the thyroid gland, causing the balance of the hormones it produces to shift.

Skin rashes have an exhaustive list of potential causes, including infections.The following are causes of rashes:
Fungal:
1.Trichophyton is a type of skin fungus that commonly causes rashes of the skin, hair, and nails. This infectious rash is called Tinea or "ringworm."
2.Candida can cause common yeast infections in moist areas like between the fingers, in the mouth, vaginal area, and also in the groin folds.
3.Other much less common fungal infections include cryptococcosis, aspergillosis, and histoplasmosis. These are fairly uncommon in healthy people and are more frequently seen in individuals with a compromised immune system as in HIV/AIDS and immune suppression due to cancer chemotherapy.

Viral:
1.Herpes simplex (HSV) types I and II may cause infections of the lips, nose, facial skin, genitals, and buttocks.
2.Herpes zoster causes chickenpox and shingles.
3.HIV causes many types of rashes, both nonspecific viral reactions as well as infection-associated rashes.
Epstein-Barr virus (EBV) is associated with many types of rashes and most commonly with mononucleosis ("mono" or "kissing disease").
4.Many other viruses, including parvovirus and coxsackievirus, cause rashes. Coxsackievirus is associated with hand, foot, and mouth disease (HFMD). Young children are particularly prone to many kinds of viral infections and illnesses.

Bacterial:
1.Staphylococcus infections are extremely common and may cause many types of rashes, including folliculitis, abscesses, furuncles, cellulitis, impetigo, staphylococcal scalded skin syndrome, and surgical wound infections.
2.Streptococcus infection may cause strep throat, scarlet fever, cellulitis, necrotizing fasciitis, and other skin infections.
3.Pseudomonas may causes all sorts of skin problems, including green discoloration of the nails, folliculitis, hot tub folliculitis, surgical wound infections, and foot infections following a penetrating injury through tennis shoes.
4.Many other types of less common bacteria cause skin rashes. These are often diagnosed by skin culture.

Parasitic:
1.Scabies is a very itchy, contagious, superficial skin infestation with a microscopic mite.
2.Lice infestations may cause different types of itchy rashes in the affected areas like scalp and nape of the neck.

Further causes of skin rashes are:
1.Drug allergies may arise from exposure to drugs containing sulfa, penicillin, antiseizure medications like phenytoin and phenobarbital, and many others.
2.Contact allergic dermatitis may develop on repeat exposure to topical products like nickel, neomycin, cobalt, fragrance, adhesives, latex, rubber, and dyes. Essentially any product may potentially induce a skin allergy.
3.Eczema or atopic dermatitis includes a wide variety of skin sensitivity in which areas of skin are dry, red, and itchy.
4.Hypersensitivity or allergic dermatitis may develop upon repeat exposure to poison oak and poison ivy.
5.Irritant dermatitis from excessive skin dryness may develop from repeat exposure to harsh soaps and cleaning chemicals.
6.Autoimmune conditions, like systemic lupus erythematosus (SLE), Hashimoto's thyroiditis, scleroderma, and other disorders in which the immune system may be overactive, often cause skin rashes.
7.Other internal diseases such as amyloidosis and sarcoidosis may cause skin symptoms and accompanying rashes.
