Bowen's Disease in Nepal
- Frequently missed — a persistent scaly genital/gluteal/periungual plaque is often labelled eczema or psoriasis for years; biopsy resolves it.
- HPV-related genital forms — genital Bowen's overlaps with HPV-driven HSIL; biopsy and typing guide management.
- Sun-exposed forms — on face, neck, hands in Nepal's high-UV climate.
- Excision standard — most Bowen's is best treated definitively; topical/imiquimod for selected genital sites.
Bowen's Disease — an In-Situ Squamous Cancer
Bowen's disease is **squamous cell carcinoma in-situ** — cancerous change confined to the epidermis, before it invades deeper. It presents as a persistent, slowly-growing, scaly/crusted, sometimes pigmented plaque. On genital sites it overlaps with erythroplasia of Queyrat and some presentations of genital HSIL.
It is "the cancer caught before it becomes invasive" — caught at this stage, it is highly treatable; left alone, a proportion invade and become true SCC. It is associated with HPV (especially genital Bowen's), sun damage (sun-exposed sites), and immunosuppression.
This page explains the condition, its diagnosis, and the range of treatments we use — including the distinction from HPV-related genital precancer.
Recognizing Bowen's
Persistent plaque
A well-defined, slowly-enlarging, scaly or crusted red/brown patch — usually solitary, present for months-to-years.
Genital appearance
On the penis/vulva a velvety red, sometimes pigmented or eroded plaque — overlapping erythroplasia of Queyrat/HSIL.
Not healing
Doesn't resolve with steroid/antifungal — the red flag for biopsy.
Occasionally pigmented/ulcerated
Pigmented Bowen's mimics melanoma; ulceration suggests early invasion — both need biopsy.
Diagnosis
Diagnosis is by **skin biopsy** — the definitive confirmation. Histology shows full-thickness epidermal atypia (SCC in-situ); dermoscopy supports but does not replace biopsy.
In genital sites we assess **HPV status** and look for associated intraepithelial neoplasia; any dermal invasion on biopsy upgrades it to invasive SCC and changes management.
Treatment
Surgical excision
The definitive treatment — complete removal with margins; curative for the lesion itself. Preferred where feasible.
Topical therapy
5-fluorouracil or imiquimod — useful for large, multifocal, or genital/penile sites where excision is morbid.
Destructive methods
Curettage + cautery, cryotherapy, or photodynamic therapy for selected lesions — effective but no histology of the whole lesion.
Surveillance
After treatment — clinical follow-up for recurrence and for other skin/HPV-related precancers.
Genital Bowen's + HPV
Genital Bowen's is strongly HPV-driven — especially HPV-16. This means the patient needs both the lesion treated AND the wider anogenital risk managed: partner awareness, cervicovaginal/anal screening where relevant, and consideration of HPV vaccination.
We coordinate this — the lesion is treated, and the underlying HPV-associated risk pathway is followed, not just the single plaque.

- Full treatment options — excision, topical, destructive, matched to site and patient.
- HPV pathway — genital Bowen's managed within the wider HPV risk.
- Surveillance — follow-up, not just treatment.
- Confidential — discreet specialist care.
Frequently Asked Questions
Is Bowen's disease cancer?
It is squamous cell carcinoma in-situ — cancerous cells confined to the surface skin layer. It is the "caught-before-invasion" stage — highly treatable.
Does it spread?
In-situ Bowen's does not metastasize — but untreated a proportion progress to invasive SCC. Treatment is definitive and removes that risk for that lesion.
Is it related to HPV?
Genital Bowen's is strongly HPV-associated. Treatment of the lesion + HPV pathway management + partner counselling are all part of the care.
What treatment is used?
Excision is definitive; topical 5-FU/imiquimod or destructive methods for selected genital/multifocal sites. We match the treatment to the site and the patient.
