PURPOSE: The aim of this study was to describe the technique of radical exc
ision of multifocal anal intraepithelial neoplasia and discuss controversia
l issues surrounding the management of this condition. METHOD: We describe
the case of a 31-year-old female with previous vulval warts, vulval squamou
s carcinoma, and recent immunosuppression who had widespread anal intraepit
helial neoplasia excised, and the resulting defect was split-skin grafted,
including the anal canal. RESULTS: Excision and split-skin grafting was suc
cessful in removing the disease and left a satisfactory cosmetic and functi
onal result. CONCLUSION: Diffuse, high-grade, anal intraepithelial neoplasi
a is rare. Excision of these lesions remains controversial but may be the b
eat option.
