This technique involves sequential excision with formal histological margin assessment between stages. Reconstruction is performed only once complete clearance is confirmed.

Staged excision is particularly valuable for:

  • Lentigo maligna
  • Large or ill-defined melanoma in situ
  • Selected thin invasive facial melanoma
  • Dermatofibrosarcoma protuberans
  • Other tumours demonstrating infiltrative or subclinical extension

The goal is precise oncologic control while preserving healthy tissue and facial cosmetic subunits.

The Science Behind It

Tumours can extend microscopically beyond what you can see. Fixed margins can either miss residual disease or remove excess healthy tissue.

Staged excision improves accuracy by:

  • excising the visible lesion with mapped margins
  • confirming margins on histology
  • re-excising only involved areas
  • reconstructing once margins are clear

Best suited for:

  • Lentigo maligna
  • Large / ill-defined melanoma in situ
  • Selected thin invasive facial melanoma
  • Dermatofibrosarcoma protuberans (DFSP)

May also be considered for infiltrative or unpredictable tumours, including:

  • Microcystic adnexal carcinoma
  • Extramammary Paget disease
  • Atypical fibroxanthoma (esp. recurrent head/neck)
  • Cutaneous leiomyosarcoma
  • Any recurrent or scar-distorted tumour

In short: tumour behaviour, not label alone, guides the margin-control strategy.

Specialist Assessment Drives Staged Excision

Nd:YAG Laser

(Available on Excel V and Excel V Plus)

Best for

Mild cases or isolated vessels.

How It Works

The long-pulse Nd:YAG laser emits energy at a wavelength absorbed by haemoglobin in blood vessels. This heat causes the targeted vessels to collapse, effectively treating both surface red veins and deeper blue veins.

Results

Treated vessels may disappear immediately or gradually fade over several weeks.

Rejuran (Polynucleotides)

(Candela VBeam Perfecta, Excel V, Excel V Plus, Sciton BBL)

Best for

Stimulating collagen and vascular remodelling to reduce persistent skin redness.

How It Works

Often recommended in combination with vascular laser or BBL treatments to enhance skin healing, texture, and redness reduction.

Combined Vascular Laser and BBL Approach

(Candela VBeam Perfecta, Excel V, Excel V Plus, Sciton BBL)

Best for

More severe cases or large areas of visible facial veins and redness, particularly in rosacea.

How It Works

This approach layers multiple vascular-targeting technologies in one session, including:

  • Nd:YAG Laser: For deeper blue or purple visible blood vessels.
  • Vascular-Tailored Settings of Broad-Based Light (BBL): For diffuse redness and widespread visible capillaries.
  • Pulse Dye Laser: (Candela VBeam Perfecta, Excel V Plus) For bright pink surface vessels and fine skin flushing.

Results

Effectively reduces visible veins, diffuse redness, and facial flushing commonly seen in rosacea.

Staged excision is never routine. It is considered following specialist evaluation of:

  • Histopathological subtype
  • Growth pattern and depth
  • Margin definition
  • Anatomical location
  • Reconstruction complexity
  • Recurrence risk

Tumours demonstrating:

  • Ill-defined borders
  • Subclinical lateral extension
  • Infiltrative architecture
  • Prior incomplete excision

may benefit from a staged, margin-controlled approach.

Specialist dermatologic surgical planning ensures oncologic safety while optimising cosmetic and functional outcomes — particularly in facial melanoma surgery.

Frequently Asked Questions

What is staged excision?

A sequential surgical technique where tumour margins are assessed in stages before reconstruction to ensure complete histologic clearance.

Which melanomas are most suitable for staged excision?

Lentigo maligna, large or ill-defined melanoma in situ, selected thin invasive facial melanomas, and recurrent melanoma with indistinct borders.

Is staged excision used for invasive melanoma?

Most invasive melanomas are treated with standard wide local excision. Staged excision may be considered in selected thin facial cases where margins are uncertain or tissue preservation is critical.

Is staged excision only used for melanoma?

No. It may also be appropriate for tumours with infiltrative growth patterns such as Dermatofibrosarcoma protuberans, Microcystic adnexal carcinoma, and other rare cutaneous malignancies.

Does staged excision involve multiple procedures?

Yes. Excision and histological margin assessment occur in stages. Definitive reconstruction is performed once complete clearance is confirmed.

What are the advantages?

  • Enhanced peripheral margin certainty
  • Reduced recurrence risk in selected tumours
  • Preservation of healthy tissue
  • Reconstruction performed with confidence once margins are clear
