One hundred and two patients with vulvar intra‐epithelial neoplasia III (VIN III) were analyzed with respect to age, sites of lesion, presence of human papilloma virus (HPV) and recurrence pattern following different treatment modalities. Recurrences were documented in 64% of patients. Patients treated with local excision had a statistically significant lower recurrence rate compared to those who underwent laser vaporization (29% vs 55.8% correspondingly). Recurrence rates were also significantly higher in patients with multifocal/multicentric lesions (P < 0.05). A group of young, HPV‐positive patients with multifocal/multicentric lesions had the highest recurrence rate. Our data suggest that VIN III should be followed for a long period of time and that a prospective study is required to clarify the effectiveness of the different treatment modalities.
