Abstract :
Background: Surgery is the most frequent treatment modality
for basal cell carcinoma but in spite of its high cure rate, the
frequency of incomplete excision varies widely (0.7-50%) among
dermatologic centers. Our case series was designed to determine
the frequency of incompletely excised basal cell carcinoma and
the related risk factors.
Methods: A total of 1424 basal cell carcinoma (1040 patients)
lesions which were excised in Razi Dermatology Hospital of
Tehran from 2006 to 2008 were evaluated in this case series and
their findings were analyzed with SPSS software.
Results: Incidence of incomplete excision was 12% and involvement
of the deep margin was observed in 54% of these lesions. Factors
related to incomplete excision were infiltrative, morpheic and
micronodular subtypes, lesions larger than 20 mm, those repaired
by skin grafts and those that received local anesthesia. There was
no statistically significant difference in age, sex, site of lesions
and childhood history of radiotherapy for tinea capitis.
Conclusion: Recognizing the risk factors related to incomplete
excision of BCCs would help us consider a wider excision margin
for high risk tumors.
