Patient Question

Hello Doctor,


I'm really worried about my 15-year-old son. He's developed a red rash with bumps all over his stomach, back, legs, buttocks, and even in his private area. He's complaining that it's really itchy, burns, and hurts. There's no fever, but I'm concerned about what this could be. Can you please help me understand what might be going on?

Considering your son's age and symptoms, several conditions could be responsible for the red, itchy, and painful rash.


Differential Diagnosis:

These conditions include psoriasis, genital herpes, scabies, ecthyma, and dermatitis, among others. Each has distinct characteristics and treatment approaches.


Symptoms and Characteristics:

Psoriasis typically begins with silvery-colored lesions that become reddish and itchy due to scratching, forming raised bumps that can be painful. Genital herpes presents as painful blisters or sores in the genital area, often accompanied by itching and burning sensations.


Differential Diagnosis Continued:

Scabies causes severe itching and may lead to reddish bumps that become painful. Ecthyma lesions are red and may not be particularly itchy but can be painful.


Treatment Options:

Treatment varies depending on the diagnosis. Psoriasis may be managed with topical steroids, retinoic acid, or coal tar. Scabies can be treated with topical medications like permethrin or benzyl benzoate. Ecthyma may require topical antibiotics such as penicillin or erythromycin. Genital herpes may necessitate antiviral medications. Dermatitis often responds well to topical steroid treatment.


Importance of Diagnosis:

It's crucial to obtain an accurate diagnosis before initiating treatment. Consulting with a dermatologist for a thorough evaluation, including a detailed medical history and possibly skin biopsy tests, is recommended.
