Perianal giant condyloma acuminatum (Buschke-Löwenstein tumor)

A 50-year-old heterosexual, HIV-negative man presented with a giant anal condyloma (Figure). He had iron deficiency anemia, a slow-growing anal wart for many years, and intermittent bleeding and pruritus. Esophagogastroduodenoscopy and colonoscopy findings were normal. Endoscopic ultrasound of the anorectum showed no anal sphincter involvement, and computed tomography did not reveal any pelvic inguinal lymph nodes. Wide-staged excision was performed and the patient recovered well with resolution of symptoms and no local recurrence at 1-year follow-up. Final pathology confirmed human papillomavirus (HPV) 6 strain and a giant condyloma acuminatum with mild atypia and no malignancy. Further examination of his oropharynx showed additional small HPV lesions, which were removed locally.
