Bowenoid Papulosis

Overview

Bowenoid papulosis is a condition caused by human papillomavirus (HPV), most commonly types 16 and 18, that presents as multiple small, pigmented papules on the genital or perianal skin. Histologically, the lesions show features of squamous cell carcinoma in situ (Bowen's disease), but clinically they tend to behave in a benign fashion in younger patients. However, the associated high-risk HPV types carry a potential for malignant transformation, especially in immunosuppressed individuals.

Key Symptoms

Multiple small (2-10 mm), flat-topped or slightly raised papules on genital or perianal skin
Brown, reddish-brown, or violaceous (purple-tinged) pigmentation
Often velvety or slightly verrucous (rough) surface
Usually asymptomatic, though mild itching may occur
Lesions may be solitary or numerous
More common in sexually active young adults

Affected Areas

Genital skin, Perianal area, Penile shaft, Vulva, Groin

Care Instructions

See a dermatologist for evaluation and biopsy to confirm the diagnosis.
Treatment options include topical imiquimod, 5-fluorouracil, cryotherapy, or laser ablation.
Electrodesiccation and curettage may be used for individual lesions.
Sexual partners should be evaluated for HPV-related disease.
Regular follow-up is important due to the potential (though low) risk of progression to invasive carcinoma.
HPV vaccination is recommended for prevention in eligible individuals.
