Giant condyloma acuminatum (GCA) commonly known as Buschke-Lowenstein tumor is a rare, aggressive, slow growing; fungating variant of condyloma that is usually found in the genital and perianal regions but may affect any portion of the anogenital region. Although clinically malignant, its histology is benign without distant metastases. The incidence is 0.1% in the general population and while the prognosis is generally good with early diagnosis and proper treatment, mortality rates as high as 20% have been reported. Human papilloma virus (HPV) types 6 and 11are implicated as etiologic factors in the development of GCA. Radical surgical excision with clear histologic margins and plastic reconstruction remains the cornerstone treatment of choice, while preventing the incidence of recurrence. Topical agents and local destructive methods can be helpful for smaller lesions and immunotherapy as an alternative for widespread and relapsed cases. The authors report the case of a 51-year-old male patient with a perianal 8 × 7 cm Buschke-Lowenstein tumor who underwent total excision and plastic reconstruction with V-Y flap technique.
