Inverse psoriasis is also referred to as hidden psoriasis. It features with rash which uncommonly affects unexposed areas of the body such as skin folds. The armpits and groin area as well as folds under the breasts and buttocks are typically affected. The condition is also accompanied by unbearable pain and itching. The reason why the rash is so itching and troublesome is because it occurs in areas of the body that are already moist. Perspiration and friction of the affected areas make the symptoms worse.
This skin condition features with rash tender to touch and it is not scaly like the one that occurs in standard psoriasis. Inverse psoriasis affects obese people more than people with normal weight and 2 to 6% of all people suffering from standard psoriasis also suffer from inverse psoriasis.
Treatment for Inverse Psoriasis
Treatment for inverse psoriasis is rather challenging and sometimes difficult since this skin condition affects the most sensitive areas of the body.
Steroid creams and ointments are highly effective in treatment of this form of psoriasis. Once they are applied the skin is not supposed to be additionally covered with plastic dressing. Overuse or misuse of steroid creams and ointments may result in excessive thinning of the skin and occurrence of unappealing stretch marks. This is a potential complication and has to be taken into consideration prior the treatment since the very disease already causes thinning of the skin. In some cases salicylic acid is used. And finally, patients can be also treated with coal tar or calcipotriene.
Additional side effects of all topical agents applied in inverse psoriasis include irritation of the skin and increased occurrence of fungal infections. This is why doctors should test the affected area for fungal infection. If there is infection the patients are treated with diluted topical steroids together with anti-yeast or anti-fungal medications.
Patients who are suffering from severe forms of inverse psoriasis may require systemic medications. Tacrolimus and pimecrolimus are typically used in eczema. These two medications can also be rather effective in alleviation of inverse psoriasis symptoms. Castellani's plant is another solution for inverse psoriasis. It is liquid, and once it has been applied on the affected skin it assists in drying of the moist lesions.
Apart from medications ultraviolet B light also contributes to alleviation of symptoms. UVB light seems to decelerate the growth of psoriatic cells.
And finally, if inverse psoriasis is highly resistant to all the previously mentioned treatment modalities the doctor may recommend treatment with biologics. Etanercept and infliximab are the last option for the most stubborn cases of the disease.
