The aim of this study was to evaluate morphologic and anatomic features of basal cell carcinoma (BCC) patients with positive surgical margins who developed recurrences in follow-ups. Patients with positive surgical margins were included in this study. Re-excision was performed in patients who were thought to have recurrence on clinical follow-ups. A retrospective analysis of patients with positive surgical margins who developed recurrences was performed. Histologically out of 148 patients, 23 (34%) were diagnosed as BCC with positive surgical margins. In the follow-up period, re-excision was performed in 7 patients with the suspicion of tumor recurrence. Among them 5 (21%) were diagnosed as recurrent BCC. Out of them 4 (80%) were diagnosed as sclerosing type and 1 (20%) was diagnosed as superficial spreading type BCC. Remaining 2 cases were diagnosed as chronic inflammation histologically. Considering the data obtained from our retrospective analysis, we suggest re-excision for BCCs with sclerosing and superficial spreading types which have positive surgical margins histologically.
