Background Basal cell carcinoma (BCC) is the most common primary cutaneous neoplasm. In several cases, it has been difficult to perform Mohs micrographic surgery in patients with a recurrent lesion, due to incomplete removal after a laser procedure.

Objective This study evaluated the subclinical extension of BCC, especially in recurrent BCC after laser procedures.

Methods We retrospectively evaluated 88 patients with 94 BCCs (70 primary, 24 recurrent after laser procedures) diagnosed and treated with Mohs micrographic surgery in the Department of Dermatology, Chungnam National University Hospital, South Korea, from June 2005 to August 2008.

Results The mean Mohs’ stages of primary and recurrent BCC after laser procedures were 1.6 and 2.3, respectively (P<0.05). The mean Mohs’ stages of histologically high- and low-risk BCC were 2.2 and 1.4, respectively (P<0.01). For low-risk BCC, the mean Mohs’ stages of primary and recurrent BCC were 1.2 and 1.8, respectively (P<0.01).

Conclusion We found a correlation with subclinical extension of BCC following preoperative laser procedures.
