Genital Psoriasis or Yeast Infection: How to Differentiate Them?

Unlike the lesions caused by psoriasis in its classic form, genital psoriasis can present in several ways, which can lead to confusion with other genital diseases, such as yeast infections. Indeed, as mentioned earlier, several factors can lead to irritation of the intimate areas. Hence, the need for an accurate diagnosis. Clinical manifestations also include red plaques with regular borders around the intimate parts.

In most cases, genital psoriasis results in burning, itching, and even pain. Furthermore, a clinical study has gathered the experiences of individuals affected by genital psoriasis. According to their findings, they have less frequent sexual intercourse, a reduced sexual desire, and they avoid sexual relations. Additionally, they may experience certain pain during intercourse.

In summary, several characteristics distinguish genital psoriasis from fungal infection:

• The primary cause of the disease:

  Genital psoriasis is an autoimmune disease linked to an immune system failure that leads to an excessive proliferation of keratinocytes and a genetic predisposition. Genital or vaginal yeast infection, on the other hand, is secondary to a fungus, the Candida Albicans.

• In terms of clinical signs:

  Genital fungal infections typically cause redness, itching, and burning. Heavy vaginal discharge is a distinctive symptom of yeast infection in women. In men, this infection leads to inflammation, while psoriasis only causes irritations, in the form of red patches.

• Localization of affected areas.

  Genital psoriasis plaques are specifically located in the genital region, including the pubis, external genital organs, and the groin. Genital fungal infections typically affect the genital parts, but can also spread to other surrounding areas, such as the groin, mucous membranes, and skin folds.

• The Diagnosis.

  The diagnosis of genital psoriasis is primarily clinical, based on the appearance of the lesions and the patient's medical history. Genital fungal infections may sometimes require diagnostic tests, such as smears, to confirm the presence of yeast. These examinations are not painful and allow the dermatologist to distinguish between these two skin conditions.

• Progression of the condition.

  Genital psoriasis plaques can be persistent and recurrent. They may evolve in the form of flare-ups, improving and deteriorating periodically. Yeast infections, on the other hand, tend to develop rapidly and can cause intense symptoms, but they generally resolve quickly with appropriate treatment.

• The treatments.

  The treatment of genital psoriasis may involve the use of topical creams based on dermocorticoids, immunosuppressants, and other medications prescribed by a dermatologist. Yeast infections can typically be treated with topical or oral antifungals, available over-the-counter or by prescription.
