The European Dermatology Forum (EDF) guidelines on surgical excision margins of BCC recommends 3 to 4 mm peripheral margins for low-risk BCC, and 5 to 10 mm peripheral margins for high-risk BCC.

Dec 29, 2019 · As a general guide, adequate surgical margins are 3–4 mm for a BCC and at least 4 mm for a low-risk SCC. There are no published guidelines for a high-risk SCC. What are histological margins? A histological margin is measured by a pathologist. It describes the amount of normal tissue bordering a tumour specimen.

For treatment of high-risk and recurrent tumors, margins of 5-6 mm or margin control of the surgical excision is required. Previous treatment, histological subtype, site and size of the lesion should be considered in surgical planning because these factors have been proven to …

The following outlines an example for basal cell carcinoma (BCC) removal; margins can be adjusted for squamous cell carcinoma (SCC) removal. Wipe the skin with an alcohol wipe. Rubbing a BCC can cause a flush of the lesion to assist in identifying the clinical margins.

May 19, 2024 · Margins for Basal Cell and Squamous Cell Carcinomas Primary and recurrent tumors get treated with marginal excisions. For example, one study showed that for low-risk basal cell carcinoma (BCC), margins are usually 3 to 4 mm, and high-risk margins are 5 to 10 millimeters based on the European Dermatology Forum with medical associations showing ...

Jul 15, 2020 · Based on the reviewed literature, we found that for primary well-demarcated BCCs smaller than 2 cm, in the low-risk group, a safety margin of 3 mm gives satisfactory results. In the high-risk group, and for lesions larger than 2 cm, a 4-6 …

Dec 9, 2024 · Basal cell carcinoma is caused by a combination of genetic and environmental factors that damage the DNA in skin cells. Key risk factors include: Ultraviolet (UV) radiation exposure: People with fair skin that burns quickly and those exposed to intense, intermittent UV radiation (like sunburns) are at higher risk of developing basal cell carcinoma.

Most BCCs are treated surgically. Long-term follow-up is recommended to check for new lesions and recurrence; the latter may be unnecessary if histology has reported wide clear margins. Excision means the lesion is cut out and the skin stitched up. Most appropriate treatment for nodular, infiltrative and morphoeic BCCs.

BCCs less than 6 mm had a clearance rate of 96% with 3-mm margins. In adjusted multivariable analysis, superficial, micronodular, infiltrative, and morpheaform subtypes were associated with larger margins, whereas clinically well-defined tumors were associated with smaller margins.

Results: BCCs less than 6 mm had a clearance rate of 96% with 3-mm margins. In adjusted multivariable analysis, superficial, micronodular, infiltrative, and morpheaform subtypes were associated with larger margins, whereas clinically well-defined tumors were associated with smaller margins.
