Clinicopathologic study of fibromatoses of extremities

This study included seven females and four males with ages ranging from 8 to 57 years [mean 30 years], with eight tumors of the lower and three tumors of the upper extremity. Tumors ranged in size from 4 to 15 cm [mean 8.9 cm]. Histologically, seven were infiltrative, one had pushing borders and three had both. Surgical margins were positive in seven cases. Follow up was available in all cases from 8 to 43 months [mean 29 months]. Six patients [54.5%] had recurrence, five with a positive surgical margin [71.4%] and one with negative surgical margin [25%]. So, surgical margin is the most predictive for clinical outcome. None of the other clinical or histological parameters correlated with the risk for local recurrence
