Objectives The purpose of this study was to investigate the clinical, pathologic, and sonographic features of local recurrent phyllodes tumors of the breast and provide evidence for diagnosing tumor recurrence. Methods A total of 127 patients with phyllodes tumors who underwent surgery from 1993 to 2012 were followed. The clinical, pathologic, and sonographic features of local recurrent tumors were analyzed. Results Of the 127 patients, pathologic diagnoses were benign, borderline, and malignant in 75 (59.1%), 41 (32.3%), and 11 (8.7%) patients, respectively. The patients were followed for a mean duration ± SD of 50.9 ± 42.1 months (range, 2–225 months). Twenty‐one patients had local recurrence, for a recurrence rate of 16.5%. The benign, borderline, and malignant recurrence rates were 14.7%, 17.1%, and 27.3%. The local recurrence in the 21 patients occurred after a mean interval of 19.4 ± 13.4 months. The mean times to local recurrence were 20.2 ± 12.1, 16.9 ± 10.8, and 20.3 ± 19.0 months for benign, borderline, and malignant tumors. The histologic characteristics of the recurrent tumors were similar to those of the initial tumors in 14 patients (66.7%), whereas the characteristics changed in 7 (33.3%). The sonographic features of the recurrent tumors were as follows: 69.4% were lobulated; 88.9% appeared as well‐defined lesions; 41.7% had posterior acoustic enhancement; 11.1% had intramural cystic areas; and 83.4% had moderate or marked blood flow. Conclusions The recurrence rate for phyllodes tumors is high. One to 2 years after surgery is the key time for follow‐up. The sonographic features contribute to recurrence diagnosis.
