Elastofibroma dorsi

Abstract

Elastofibroma dorsi is a rare benign soft-tissue tumor which is solid, ill-defined and marked by slow growth. It is usually found in the subscapular region of older individuals. We report here the case of a 56-year-old Japanese man with elastofibroma dorsi which was located in the left subscapular region and measured 50 × 70 mm in size. The mass was very similar to tumors previously reported, both clinically and histologically. This entity has only rarely been described in the dermatological literature, but it should be considered in the differential diagnosis of subscapular complaints elderly patients.

Acquired disorders of elastic tissue: part I. increased elastic tissue and solar elastotic syndromes

“…39,45,46 Magnetic resonance imaging shows a poorly defined mass with hypointense internal tracts. 39,47 Histopathology. Histopathologic examination reveals fragmented elastic fibers studded with globular aggregates of elastic material that confer a serrated appearance to the fibers (Fig 3).…”

“…Histopathologic examination reveals fragmented elastic fibers studded with globular aggregates of elastic material that confer a serrated appearance to the fibers (Fig 3). 39,42,47,48 A mixture of swollen, eosinophilic collagen fibers intertwined with elastic fibers, along with fibroblasts and fat cells of varying sizes, is typically seen. 44 At low-power magnification, the tumor appears acellular and lacks the mitotic features of a neoplastic process.…”

“…The clinical differential diagnosis of elastofibroma includes lipoma, liposarcoma, synovial sarcoma, desmoid tumor, malignant fibrous histiocytoma, and neurofibroma, each of which can be differentiated on the basis of histologic features. 39,47 Treatment. The definitive treatment of elastofibroma is local excision.…”

“…However, as no case of malignant transformation has been reported, no treatment may be necessary, although an excisional biopsy should be considered in cases of a high clinical index of suspicion for a malignant process. 47 …”

Elastofibroma dorsi: histologic and echographic considerations

“…First described by Jarvi and Saxen in 1961, 1 few cases have been reported in the dermatology literature 2–4 . In ambulatory practice this entity is less commonly known, because elastofibroma usually arises from the deep connective tissue, between the lower portion of the scapula and the chest wall.…”
