SelectedWhat are Skin & Soft Tissue Excision Procedures?
Skin and soft tissue excisions are minor surgical procedures performed to remove abnormal, infected, painful, or recurrent tissue. Common indications include cysts, granulomas, fistula/fossa lesions, and pilonidal sinus disease.
Procedures are typically carried out under local anaesthetic in a clinic setting. Where appropriate, removed tissue is sent for histology to confirm diagnosis and exclude underlying pathology.
Why might I need an excision?
Some skin and soft tissue conditions do not resolve with medication alone or tend to recur if not fully removed. Surgical excision provides definitive treatment, symptom relief, and reduces the risk of infection or complications.
You may need assessment or excision if you have:
Procedures we offer

Skin cysts (e.g. epidermoid or sebaceous cysts) are benign but may become painful or infected.
What it involves:

Fossa or fistula-type lesions can cause chronic discharge or infection.
What it involves:
Excision of Granuloma
Granulomas are small areas of chronic inflammation that may bleed, discharge, or fail to heal.
What it involves:
Excision of Pilonidal Sinus
Pilonidal sinus disease commonly affects the upper buttock cleft and can be recurrent and painful.

Where possible, attend your blood test between 7am and 12pm. Please wait until any short-term illness or infection has fully resolved before testing. Avoid intense exercise for 24–48 hours beforehand, as this can affect certain markers.
Fasting is not always required, but some tests may recommend it. If fasting is advised, avoid food for 8–12 hours before your appointment and drink water only. Stay well hydrated, as this helps with sample collection and accuracy.
Continue prescribed medications unless advised otherwise by your clinician. Avoid vitamin, mineral, or biotin supplements for at least 24–48 hours before your test, as these can interfere with results. If you are unsure about any medication or supplement, please let us know before your appointment.
For hormone-related tests, timing within your menstrual cycle may be important. If relevant, follow any specific guidance provided on your test page.
If you have any questions or special circumstances, our team is happy to advise before your appointment.
