Elastofibroma dorsi: an unusual case of a subscapular nodular mass

Elastofibroma dorsi is a benign, slow-growing soft tissue tumor. Poorly symptomatic, it raises an important differential diagnosis with benign and malignant tumors of the subscapular region, and with a differential diagnosis with shoulder pain and snapping scapula. It is seen in elderly women and occurs more frequently in the subscapular region, although it has been reported in several locations. We report the case of a 58-year-old woman who presented with upper gastrointestinal bleeding. During the physical examination, a mass was found in the right subscapular region. Months later, the patient presented with pain on right arm motion and an increase in the size of the mass. Complete surgical excision was performed. The patient is free of symptoms with no recurrences of the tumor so far. Consider this benign tumor if a lipoma-like nodule or mass becomes symptomatic.
