What would be the cause of red raised oily smelly skin patches under folds skin?

Red raised oily smelly skin patches under folds of skin can be caused by a variety of factors, including:

1. Intertrigo: This is a skin condition that occurs in areas where skin rubs against skin, such as under the arms, under the breasts, or between the toes. Friction and moisture can cause the skin to become irritated and inflamed, which can lead to redness, raised patches, and an unpleasant odor. Intertrigo can be treated with over-the-counter or prescription antifungal medications.

2. Candidiasis: This is a fungal infection that can affect the skin and mucous membranes, including the skin under folds of skin. Candidiasis can cause red, raised, and itchy patches of skin, as well as a burning or stinging sensation. Prescription antifungal medications are used to treat candidiasis.

3. Erythrasma: This is a bacterial infection that causes red, scaly patches of skin, most commonly in the underarms, groin, and perineum. Erythrasma can be treated with antibiotics or antibacterial soaps.

4. Lichen simplex chronicus: This is a chronic skin condition that causes red, raised, and itchy patches of skin. Lichen simplex chronicus can occur anywhere on the body, but it is most common on the arms, legs, and neck. The cause of lichen simplex chronicus is unknown, but it may be related to stress, anxiety, or certain medications. Treatment options include topical steroids, antihistamines, and light therapy.

5. Atopic dermatitis: This is a common skin condition that causes red, itchy, and inflamed skin. Atopic dermatitis can affect people of all ages, but it is most common in children. The cause of atopic dermatitis is unknown, but it is thought to be related to allergies, asthma, and eczema. Treatment options include topical steroids, antihistamines, and phototherapy.

If you are experiencing red raised oily smelly skin patches under folds of skin, it is important to see a doctor to get a diagnosis and appropriate treatment.
