Mohs micrographic surgery for verrucous carcinoma: a review of the literature

Verrucous carcinoma is a rare, low grade variant of squamous cell carcinoma that rarely metastasizes but tends to display aggressive local behavior. Wide local excision is the most common treatment, but has high rates of local recurrence, ranging from 19 to 75% in the literature. The cases of verrucous carcinoma treated with Mohs micrographic surgery in the literature, as well as a previously unpublished case is summarized. PubMed was searched for terms related to verrucous carcinoma and Mohs micrographic surgery, and articles reporting cases of verrucous carcinoma treated with Mohs were reviewed and summarized. A previously unpublished case treated at our institution was also reported. Thirty-eight cases of verrucous carcinoma treated with Mohs surgery were analyzed. The average age of patients was 52.1, and 50% were male. The most common sites were the foot (47%) and the anogenital region (34%). Lesion duration ranged from 0.17 to 40 years with a mean of 4.8 years, and tumor diameter ranged from 1 to 10 cm with a mean of 4.6 cm. The local recurrence rate following Mohs was 16%, with nodal metastasis occurring in 3% and no cases of distant metastasis. As verrucous carcinoma demonstrates locally aggressive behavior and a high risk of local recurrence, Mohs micrographic surgery should be considered as first line treatment. Further research directly comparing wide local excision to Mohs surgery is needed.
