Dermatitis associated with Psoriasis

Skin cancer

Kocsard (1976) reported that psoriasis is virtually absent in patients with sun-related skin cancer or solar keratosis. The prevalence of the combination of psoriasis and melanoma seems to be very low or lower than the expected number of cases (Proctor et al, 1981).
However, Halprin et al (1982) reported a high frequency of skin cancer with psoriasis in those who had undergone treatments such as: Ultraviolet rays, Metrotexate, X-rays or Corticosteroids among others.

Various types of Eczema

Seborrhoeic Dermatitis

Diagnosing psoriasis or seborrhoeic dermatitis on the scalp or joints is very difficult. Seborrhoeic dermatitis is typically distinguished by a more yellowish and greasy appearance, sometimes accompanied by hair loss and the lesions are not as easily palpable as in psoriasis.
Atopic Dermatitis

According to Puerschel (1973) coexistence between psoriasis lesions and atopic dermatitis is rare. He found only 3 cases of psoriasis in a group of 1,170 patients with atopic dermatitis. It is recommended to see a dermatologist for histology to determine whether it is psoriasis or atopic dermatitis.

Contact eczema

When the skin comes into contact with a substance to which one is allergic, it causes redness and itching of the skin. In 1967 Steigleder & Orfanos reported that in most of their patients studied it was likely that the psoriasis lesion was caused by contact eczema.
