The different techniques
Simple excision (scalpel)
- The most common technique for small superficial lesions.
- An incision adapted to the shape and size of the lesion, closed with sutures.
- Advantages: quick procedure, generally a fine scar when performed under good conditions.
- Limitations: limited lesion size and the need for histopathological analysis depending on the indication.
Fusiform excision and layered closure
- For the removal of larger lesions or when the scar axis must be respected for a better aesthetic result.
- Closure in multiple layers (subcutaneous then cutaneous) to limit tension on the skin.
Wider excision (extended margins)
- Indicated in cases of suspicious or confirmed lesions (certain skin cancers), to ensure clear margins around the lesion.
- May require skin reconstruction (flap, skin graft) depending on the size and location.
Instrumental alternatives (electrosurgery, laser, cryotherapy)
- Certain benign lesions can be treated by laser, electrocoagulation or cryotherapy.
- These techniques may leave less tissue available for histological examination; they have specific indications and limitations with regard to diagnosis.
Pre-operative consultation
- Medical history: collection of medical history, current treatments (anticoagulants, antiplatelet agents), allergies, history of healing problems or keloids.
- Clinical examination: inspection of the lesion (size, colour, depth), examination of surrounding tissues and pre-operative photographs for traceability.
- Discussion of the technical choice: simple excision, extended margins, possibility of skin reconstruction, need for histopathological examination.
- Information on risks, the operative procedure, aftercare and alternatives.
- Provision of a quote if the procedure falls under aesthetic surgery and the mandatory 15-day reflection period for any procedure performed for aesthetic purposes.
- Informed consent and organisation of any sample collection for histological analysis.
Procedure
- Anaesthesia: most often local. Sedation or general anaesthesia may be proposed if the size, location or patient's condition requires it.
- Duration: variable (generally 10 to 60 minutes depending on the size and complexity).
- Main steps: antisepsis, localisation of the lesion, local anaesthesia, excision according to the chosen technique, haemostasis, closure by sutures or skin reconstruction, dressing.
- Hospitalisation: most often day surgery (discharge on the same day). For extensive excisions or those requiring monitoring, a short stay may be planned.
- Traceability: operative report, submission of the specimen for histopathology if indicated, prescriptions and written instructions for post-operative care.
Post-operative recovery
- Pain and discomfort: generally moderate, controlled by simple analgesics.
- Local care: dressings, cleaning as prescribed, possible application of healing cream after suturing.
- Suture removal: depending on the area, between 7 and 21 days (earlier on the face, later on the trunk and limbs).
- Activities: return to work often within a few days if the activity is not physical; sports and intense efforts are generally deferred for 2 to 4 weeks depending on the extent of the procedure.
- Monitoring: warning signs (excessive redness, increasing pain, purulent discharge, fever) require medical contact.
- Scheduled follow-up: post-operative consultation for review and delivery of histopathology results if a specimen was sent.
Results and limitations
- Evolution: the aesthetic result evolves over several months; the scar gradually fades but remains visible.
- Variability: the appearance and quality of healing depend on individual factors (skin type, age, location, skin tension, smoking).
- Durability: if the lesion was benign, excision is definitive; in the case of a tumorous lesion, dermatological or oncological follow-up may be required.
- Importance of histological analysis: it may modify subsequent management (need for further excision, enhanced surveillance).
Risks and complications
- General complications: infection, bleeding or haematoma, prolonged pain.
- Local complications: hypertrophic or keloid scar, wound dehiscence, loss of sensitivity (paraesthesia) or, more rarely, skin necrosis.
- Anaesthesia-related risk: local or general reactions (rare).
- Diagnostic risk: discovery of an unforeseen malignant lesion requiring additional treatment.
- These risks remain rare and will be detailed and contextualised during the medical consultation.
Alternatives and non-surgical options
- Monitoring: regular examination if the lesion does not have a suspicious character.
- Cryotherapy: for certain superficial benign lesions (limitations: no histological analysis).
- Laser or electrocoagulation: suitable for selected lesions; may compromise the possibility of histopathological examination.
- Aesthetic medicine (peels, injections): not indicated for the treatment of a skin lesion requiring histological diagnosis.
- The choice will depend on the nature of the lesion, the need for diagnosis and the patient's objectives.
