Purpose:
This study aimed to evaluate the outcome of patients with Buschke-Löwenstein tumor or circumferential anal carcinoma in situ who underwent wide local excision with flap or skin graft coverage of the wound.
Methods:
A retrospective review was conducted of all patients operated at Kaiser Permanente Los Angeles Medical Center during a 6-year period. Outcome measures included postoperative complications, functional results, recurrence rate, and re-intervention rate.
Results:
Of 152 patients operated for dysplastic anal lesions or tumors, 10 (7%) underwent wide local excision for Buschke-Löwenstein tumor or circumferential anal carcinoma in situ [men 70%, mean age 36 years]. Median duration of symptoms was 5 years. Eighty percent of patients had prior operations and 50% were positive for the human immunodeficiency virus. Mean size of the lesion was 41 cm(2). Microscopic margin positivity was noted in 60%. Wound was closed with house advancement flap in majority of patients. Only one patient had fecal diversion. Median length of stay was 2 days. Postoperative complications were noted in 50% of patients. Rate of transient postoperative incontinence was 30%. Recurrent disease was noted in 3 patients with the human immunodeficiency virus [median follow-up: 18 months]. All recurrences were treated with local fulguration or medication.
Conclusion:
Wide local excision with flap or skin graft coverage is an option for patients with Buschke-Löwenstein tumor or circumferential anal carcinoma in situ. Close postoperative surveillance is advised due to the risk of recurrent disease, especially in patients with the human immunodeficiency virus.

Cells are regularly exposed to mutagens—factors in the environment that can damage DNA and generate mutations. UV radiation is one of the most common mutagens and is estimated to introduce a significant number of changes in DNA. These include bends or kinks in the structure, which can block DNA replication or transcription. If these errors are not fixed, the damage can cause mutations, which in turn can result in cancer or disease depending on which sequences are...
