Treatment of basal cell carcinoma (BCC) should completely remove the tumour
whilst preserving the maximum amount of normal surrounding skin. Therefore
, treatment is a compromise between safe excision margins and obtaining a s
atisfactory cosmetic result. We report the results of a prospective study o
f 63 patients who underwent excision of well-demarcated BCCs in the head an
d neck region. The surgical excision margin used was 2 mm. Histological ass
essment confirmed complete excision in 95% and there was no evidence of rec
urrence of the BCC over a 24-month follow-up period in all patients. We pro
pose that a clinical excision margin of 2 mm is adequate for treatment of s
imple, well demarcated BCCs arising in the head and neck.
