Erythroplasia of Queyrat in Nepal
- Frequently missed — a persistent red glans plaque is often treated as balanitis/fungal for months-to-years.
- HPV-16 driven — biopsy confirms and typing is assessed; the wider HPV pathway is managed.
- Circumcision link — phimosis and lack of circumcision are the major risk factors; circumcision is both treatment and risk-reduction.
- Excision/Penile-preserving options — matched to size and patient preference.
Erythroplasia of Queyrat — Penile Cancer In-Situ
Erythroplasia of Queyrat is the **penile form of Bowen's disease** — squamous cell carcinoma in-situ of the glans penis. It presents as a persistent, well-defined, velvety-red, shiny, non-healing plaque on the glans or inner foreskin.
It is strongly associated with **HPV-16** and with lack of circumcision (penile SCC risk is dramatically lower in circumcised men). Untreated, a significant proportion progress to invasive penile squamous cell carcinoma.
Caught at this stage it is highly treatable. This page explains the condition and its management — including the underlying HPV pathway.
Recognizing It
Velvety red plaque
A well-defined, shiny, velvet-textured red patch on the glans or inner foreskin — characteristic.
Persistent + non-healing
Present for months; doesn't respond to antifungals or balanitis treatment.
Often uncircumcised
Almost always in uncircumcised men, often with underlying phimosis.
May ulcerate
Ulceration or thickening suggests progression toward invasive SCC — needs urgent biopsy.
Diagnosis
**Biopsy is mandatory** — the appearance strongly suggests EQ but only histology confirms SCC in-situ and excludes invasion (which changes the treatment entirely).
We assess HPV status and look for associated penile intraepithelial neoplasia. Any invasive component on biopsy upgrades it to invasive penile SCC — a different management pathway.
Treatment
Surgical excision/circumcision
Definitive — circumcision both treats the lesion and removes the major ongoing risk factor; Mohs or partial excision for larger lesions.
Topical therapy
5-fluorouracil or imiquimod for selected, smaller, biopsied lesions — organ-preserving.
Laser/photodynamic
Tissue-preserving ablation for selected lesions where excision is morbid.
HPV pathway + surveillance
Partner counselling, anogenital HPV assessment, and structured follow-up for recurrence or new lesions.
The HPV Connection
EQ is strongly HPV-16 driven — treatment of the plaque is only half the work. The associated HPV risk pathway (partners, other sites, smoking, vaccination) is managed alongside.
We don't just remove the lesion — we address the underlying risk so a second lesion is less likely to appear.
EQ Care & Costs
| Service | What It Includes | Cost (NPR) |
|---|---|---|
| Specialist consultation | Assessment + biopsy | Rs. 450 |
| Biopsy | Diagnostic + excludes invasion | Lab rate |
| Circumcision/topical/laser | Definitive treatment | Per case |
| HPV pathway + surveillance | Underlying risk management | Coordinated |
Transparent pricing; confirm current rates on booking.
Why Thamel Clinic for EQ
- Early biopsy — we biopsy the persistent red plaque, not treat it as balanitis for years.
- Organ-preserving options — topical, laser, circumcision, or excision matched to the lesion.
- HPV pathway managed — the underlying risk addressed, not just the lesion.
- Surveillance — follow-up for recurrence or new lesions.
- Confidential — discreet, non-judgmental specialist care.
Frequently Asked Questions
Is erythroplasia of Queyrat cancer?
It is SCC in-situ — cancerous cells confined to the surface layer. Caught here it is highly treatable; untreated it can become invasive penile SCC.
Is it related to HPV?
Yes — strongly HPV-16 driven. Treatment of the lesion + management of the HPV pathway + partner counselling are all part of the care.
Does circumcision help?
Yes — circumcision both treats the lesion and removes the main ongoing risk factor; it is often the definitive treatment for EQ.
What if it's already invasive?
Biopsy distinguishes in-situ from invasive. Invasive penile SCC is a different pathway — urgent specialist/oncology referral; we coordinate this.
