Surgical treatment of elastofibroma dorsi. Personal experience and a review of the literature.

AIM
To report our experience in treating elastofibroma, an uncommon lesion, usually arising into subscapular area; it has been included between soft tissue tumors and is characterized by progressive growth and benign behavior METHODS: Patients with an histologically proved elastofibroma, operated at our ward unit over a 3-year period, entered this study. Early results of surgical treatment have been analyzed and compared to those of Literature, focusing on selection criteria, hospital morbidity and relative risk factors RESULTS: Fourteen surgical procedures have been performed on 11 patients; EF presented as bilateral on 3 patients (27.3%) and these patients were treated with sequential 2-stages excision. All patients received complete surgical resection according to marginal excision technique; mean operative time was 75.8 ± 21.4 min. (range 55-135) while mean size of resected EF was 8.57 ± 2.2 cm. (range 5-12). Three patients developed significative postoperative seroma (21.4%), while neither hemorrhages nor recurrences have been observed. Increased B.M.I. was the only factor significantly related to hospital morbidity at univariate analysis (p = 0.0339) CONCLUSIONS: Patients carring elastofibroma larger than 5 cm. and symptomatic should undergo surgical treatment; marginal excision represents the standard technique; we recommend the use of ultrasound energy device for tissue dissection: its current use seems to prevent postoperative bleeding. Development of postoperative seroma seems related to increased patient's B.M.I. and to larger size of EF, rather than to different methods of dissection.
