Exploring Epidermodysplasia Verruciformis: A Case Report, Treatment Strategies, and Emerging Therapies

Abstract

Abstract Introduction/Objective Epidermodysplasia verruciformis (EV) is a rare cutaneous disorder with both inherited and acquired forms. Inherited cases involve mutations in genes such as ERV1 and ERV2, crucial for HPV immunity, while acquired cases affect immunocompromised individuals. EV is linked to cutaneous squamous cell carcinoma (SCC), highlighting the need for prompt diagnosis and treatment. Methods/Case Report A 54-year-old HIV-positive man was referred with a persistent, itchy eruption on his forearms despite given ARV regimen, oral retinoids and topical therapies. Physical examination revealed hypopigmentation and hyperkeratotic plaques on both forearms. Histologic examination revealed large cells with blue-gray cytoplasm and perinuclear halo in the upper epidermis, consistent with EV. Although advised for papilloma virus vaccination and planned for a trial of topical cidofovir, the patient was lost to follow-up. Treatment strategies for EV vary depending on lesion severity. Severe keratinized or precancerous lesions typically require surgical removal as the first-line approach. For early-stage EV with few small lesions, 5-FU, cidofovir, glycolic acid, and imiquimod is recommended. Tazarotene 0.5% cream used twice weekly has shown success in resolving lesions within 14 days. Topical imiquimod’s efficacy appears variable. In HIV-positive patients with EV, topical 1% cidofovir showed success in some cases. Systemic and topical retinoids are advised for diffuse lesions, with electrocautery or cryotherapy as options if initial treatments fail. HPV vaccination combined with oral acitretin, topical tretinoin and imiquimod led to lesion flattening. Continuous low-dose isotretinoin achieved prolonged remission of EV, but its efficacy in acquired EV remains unclear. Topical methyl aminolevulinate followed by photodynamic therapy has also shown promise. Results (if a Case Study enter NA) NA Conclusion Since its discovery in the 1970s, Acquired EV has been observed across diverse demographics, including HIV patients and organ transplant recipients. Advanced HPV typing and sequencing techniques aid in predicting SCC risk. Emerging treatments like topical cidofovir and combination therapies show promise, necessitating larger clinical trials for validation.
