challenge of recurrent basal cell carcinoma

ABSTRACT

Recurrent basal Cell Carcinoma "B.C.C." is a much more difficult problem to diagnosis and to treat compared to primary B.C.C. In this work 35 cases of recurrent B.C.C. were studied to conclude the real reasons of recurrence to prevent and to establish an accurate way to follow up and to predict recurrences. A trial was made to choose the best way of ablative and reconstructive steps of treatment. Recurrence rate after treating recurrent B.C.C. in such series was 20% which is near the experience of other authors. This is much higher than the expected recurrences after treating primary B.C.C. Surgery was adopted in 27 cases and radiotherapy in 8 cases. the disease free survival rate at a mean period of 3 years as 81% and 75% for the groups treated by surgery and radiotherapy respectively. The highest rate of a second recurrences was observed in their morphed like lesions [four out of six cases] and lesions around fusion lines [five out of six].Post radiation recurrences were more difficult to predict and to treat; nevertheless the final disease free survival for such group was almost equal to the post surgery recurrences
