Pseudoepitheliomatous Hyperplasia Skin ICD-10, Symptoms, Causes, Treatment

Read about Pseudoepitheliomatous Hyperplasia Skin ICD-10, Symptoms, Causes, Treatment.

Pseudoepitheliomatous Hyperplasia is a benign reactive process that arises in reaction to chronic irritation, inflammation, or injury to the skin. Squamous epithelium grows excessively, resulting in thicker layers that mimic squamous cell carcinoma. Though it may have a frightening appearance, PEH is actually a cutaneous reaction rather than a cancerous growth.


    Depending on the underlying reason and the location of the affected area, the symptoms of pseudoepitheliomatous hyperplasia may vary. 

    Typical signs consist of:

    • Skin lesions or plaques that are thick and elevated
    • Inflammation and redness
    • Erosion or ulceration of the skin
    • Itching and soreness in the afflicted area

    It's vital to diagnose correctly because these symptoms can mimic other skin problems.

    There are several things that might cause pseudoepitheliomatous hyperplasia, like:

    Chronic Skin Irritation

    Scratching, rubbing, or chemical exposure can cause PEH by irritating the skin repeatedly. This discomfort may be exacerbated by diseases like psoriasis or chronic dermatitis.


    Pseudoepitheliomatous Hyperplasia can result from repeated fungal or bacterial infections. These infections may cause squamous epithelium overgrowth due to inflammation.

    Trauma or Injury

    The onset of PEH can be triggered by skin trauma, such as burns, cuts, or surgical wounds. In reaction to the injury, the body speeds up cell growth, which may lead to the development of hyperplastic tissue.


    Dermatologists must perform a thorough examination in order to correctly diagnose pseudoepitheliomatous hyperplasia. Usually, the diagnosis entails:

    • Extensive examination of the affected area
    • Reviewing the patient's medical history and symptoms
    • A skin biopsy is performed for microscopic examination.

    To distinguish PEH from other skin disorders that could exhibit similar symptoms, a microscopic study of the biopsy sample is essential.


    The goal of Pseudoepitheliomatous Hyperplasia treatment is to treat the underlying cause, alleviate symptoms, and return the skin to its normal appearance. Possible choices are as follows:

    • Topical corticosteroids reduce inflammation and facilitate healing.
    • Antifungal or antibacterial drugs to treat underlying infections
    • To soothe and hydrate the affected area, use moisturizers or emollients.
    • If the lesions are large or chronic, surgery may be required to remove them.
    • Cryotherapy or laser therapy can be used to eliminate hyperplastic tissue.

    Treatment is determined by the severity and location of the ailment, as well as the individual patient's preferences and medical history.


    Pseudoepitheliomatous Hyperplasia may not always be preventable, however there are several steps that can be taken to lower the risk or effectively manage the illness. These consist of:

    • Avoiding prolonged exposure to irritants or allergens
    • Keeping your skin clean and routinely hydrating
    • Addressing any skin infections or wounds right away
    • Consult a doctor if you have persistent or recurrent skin problems

    People who are prone to chronic skin disorders must see a dermatologist frequently since early detection and treatment can avert consequences.
