Elastofibroma dorsi: Review of eight cases.

PURPOSE

Elastofibroma dorsi (ED) is a rare, benign soft tissue tumor arising from connective tissue and usually found in the subscapular region. We conducted this retrospective study to contribute to a better understanding of this tumor, the pathogenesis of which is still unclear.

METHODS

We reviewed the medical records of eight patients treated for ED at our institution between 2003 and 2008.

RESULTS

All patients were right-handed and all except one were female. The tumor was located on the right in two patients, on the left in one, and bilaterally in five. All patients underwent complete marginal resections. The resected tumors ranged in size from 5 cm to 12 cm. The only postoperative complication was seroma, observed in two patients. No recurrences have been observed in follow-up ranging from 15 days to 5 years.

CONCLUSIONS

We could not establish a relationship between the side of the dominant hand and the tumor location. If this tumor becomes symptomatic, local excision is the best treatment; however, as malignant transformation has not been reported, follow-up is recommended for asymptomatic lesions.
