Vulval Granuloma Fissuratum: Symptoms, Causes and Treatment in the UK

Vulval granuloma fissuratum is a clinical term used to describe a specific type of chronic, non-healing crack (fissure) that develops in the folds of the vulva. While granuloma fissuratum was originally described behind the ears due to friction from spectacles, it is now recognised in the genital area as a reactive skin condition. It typically presents as a reddish, firm plaque with a distinct linear split in the centre.

Unlike acute tears that heal within a few days, these fissures are persistent. They represent the skin's attempt to react to ongoing trauma or irritation. In the UK, this condition is often managed within primary care or specialist vulval clinics, following NICE (National Institute for Health and Care Excellence) principles regarding the management of chronic vulval symptoms.

The hallmark of vulval granuloma fissuratum is a sharp, stinging pain. This pain is typically very localised to one spot, often in the posterior commissure (the area at the bottom of the vaginal opening) or within the folds of the labia minora. Patients often describe the sensation as a "paper cut" that refuses to heal.

Key features include:

• Persistent Fissuring: A linear crack that may slightly bleed or ooze when stretched.
• Redness and Swelling: The edges of the crack may appear thickened or raised (hypertrophic).
• Discomfort during Activity: Pain is often exacerbated by walking, cycling, or sexual intercourse (dyspareunia).
• Stinging: Contact with urine or scented soaps can cause an intense burning sensation.

Granuloma fissuratum is rarely a standalone condition; it is usually a reactive process. The British Association of Dermatologists notes that chronic inflammation is the primary driver. Common causes in British patients include:

• Mechanical Friction: Tight-fitting clothing, frequent cycling, or repetitive friction during intercourse can prevent the skin from knitting back together.
• Underlying Skin Disorders: Conditions such as lichen sclerosus, lichen planus, or chronic eczema make the vulval skin fragile and prone to splitting.
• Oedema (Swelling): Chronic swelling of the vulval tissues can put tension on the skin, leading to cracks in the natural folds.
• Allergic Contact Dermatitis: Reactions to laundry detergents, wet wipes, or sanitary products can weaken the skin barrier.
• Oestrogen Deficiency: In menopausal patients, the thinning of the skin (atrophy) significantly increases the risk of fissuring.

It is essential to seek a professional diagnosis for any persistent vulval lump, bump, or crack. A GP or specialist will typically perform a visual examination under a good light source. In the UK, healthcare providers follow a cautious approach to ensure that a non-healing fissure is not a sign of something more serious, such as vulval intraepithelial neoplasia (VIN) or early-stage skin cancer.

If the fissure does not respond to initial treatment within a few weeks, a small skin biopsy may be recommended. This is a simple procedure, usually performed under local anaesthetic, to examine the tissue cells. Swabs may also be taken to rule out secondary infections like Candida (thrush) or bacterial vaginosis, which can complicate the healing process.

The goal of treatment is to reduce inflammation and allow the skin barrier to repair itself. Following NHS guidance for vulval skin care is the first step in management.

Medical Treatments:

• Topical Corticosteroids: A potent steroid ointment (such as clobetasol propionate) may be prescribed to reduce the thickened edges of the granuloma and calm inflammation.
• Oestrogen Creams: If vaginal atrophy is a contributing factor, topical oestrogen can help thicken and strengthen the skin.
• Barrier Creams: Simple ointments like white soft paraffin can protect the fissure from the irritating effects of urine.

Self-Care Strategies:

• Avoid all scented soaps, bubble baths, and "feminine hygiene" wipes. Wash with plain water or a soap substitute.
• Wear loose-fitting cotton underwear and avoid tight leggings or jeans.
• Use a lubricant during intercourse to reduce mechanical friction.
• Gently pat the area dry after washing rather than rubbing.

If you are struggling with a painful crack in the vulval area, you can speak to a GP online for a private and discreet consultation. An online doctor can review your symptoms, discuss your medical history, and provide advice on appropriate over-the-counter treatments or prescription-strength creams.

An online consultation is a convenient way to get an initial assessment, especially if you feel embarrassed or find it difficult to book a face-to-face appointment. The doctor can help determine if your symptoms are likely to be granuloma fissuratum or if you require a physical examination and swabs at a local clinic. If you need time off work due to severe discomfort, you may also be able to request a sick note during your consultation.
