title: Histologic evolution of basal cell carcinoma recurrence.
abstract: The biological behavior and appropriate therapy of recurrent basal cell carcinoma (BCCA) is controversial, with some studies suggesting that this tumor becomes more aggressive with each recurrence, and other studies indicating that the majority are aggressive from the onset. The authors studied the histologic evolution of BCCA by comparing 29 original tumors with their subsequent recurrences to determine if there were any predictable histologic changes. There were borderline statistically significant changes only in degree of fibrosis, prominence of nucleoli, and mitotic frequency. There were no statistically significant changes in any of the other parameters, including those that were shown previously to be predictive of recurrence or aggressive behavior. The results of this study clearly indicate that the majority of recurrent BCCAs are aggressive from the onset, and that in many cases this can be predicted from the histomorphology of the original tumor.
