Key Points about Bowen’s Disease:
- Definition: Bowen’s disease, also known as squamous cell carcinoma in situ, is an early form of skin cancer confined to the epidermis, characterized by scaly, red patches that can become invasive if left untreated.
- Causes:
- Prolonged exposure to ultraviolet (UV) radiation.
- Human papillomavirus (HPV) infection, especially in genital Bowen’s disease.
- Immunosuppression (e.g., organ transplant recipients).
- Symptoms:
- Slowly enlarging, red, scaly, and well-demarcated plaques.
- Lesions can appear on sun-exposed areas, such as the face, hands, and lower legs.
- Itching or irritation may be present, but lesions are usually asymptomatic.
- Diagnosis:
- Clinical examination of the skin lesion.
- Skin biopsy to confirm histological features of Bowen’s disease.
- Dermoscopy may help differentiate from other conditions like psoriasis or eczema.
- Management:
- Topical treatments such as 5-fluorouracil or imiquimod.
- Cryotherapy or photodynamic therapy for localized lesions.
- Surgical excision for larger or resistant lesions.
- Regular follow-up to monitor for recurrence or progression to invasive squamous cell carcinoma.
- Complications:
- Progression to invasive squamous cell carcinoma if untreated.
- Recurrence of the lesion, requiring repeated treatments.
- Scarring or pigmentation changes post-treatment.
