Overview

Historical Perspective

Elastofibroma was first discovered by Jarvi and Saxen, in 1961.[1]


Classification

There is no established system for the classification of elastofibroma.


Pathophysiology

Elastofibroma dorsi is a rare, slow growing, ill-defined soft tissue mass of the chest wall. It occurs most in the periscapular region.It is commonly located beneath latissimus dorsi and rhomboid major muscles near to the inferior angle of the scapula. It is a benign neoplasm with clinical appearence of a malignant tumor. [2]

The exact pathogenesis of elastofibroma dorsi is not fully understood. It is thought that elastofibroma dorsi is the result of subclinical microtrauma, reactive hyperplasia of elastic fibres and increased production of fibrous tissue. [3]

Elastofibroma often has bilateral location in the thoracic wall.[4]

On gross pathology, characteristic findings of elastofibroma include:[5]

  • A solitary, poorly circumscribed, heterogeneous, soft-tissue mass
  • Cut section are firm with grayish-white areas

On microscopic histopathological analysis, characteristic findings of Elastofibroma include: [6]

  • Eosinophilic, beaded elastic fibers with Verhoeff's elastic stain
  • Many fragmented fibers with appearance of beads on a string


Causes

The cause of elastofibroma dorsi has not been identified. Subclinical microtrauma could be one of the reasons. [3]


Differentiating Elastofibroma dorsi from Other Diseases

Overview

Elastofibroma is an ill-defined fibroelastic tumor-like condition made up of enlarged and irregular elastic fibers. On gross pathology, ill defined, nonencapsulated, rubbery, and firm, white lesion with interspersed fat are characteristic findings of elastofibroma. On microscopic histopathological analysis, heavy dense bands of collagenous tissue dissected by fat and abnormal elastic fibers are characteristic findings of elastofibroma . The elastic fibers are usually quite large and are easily identified. The elastic fibers are coarse, thick, and darkly eosinophilic, often fragmented into globules, creating a "string of pearls" or "pipe cleaner" appearance. Degeneration will cause the elastic fibers to appear as globules with a serrated or prickled edge. Elastofibroma may be caused by either trauma, genetic mutation, or systemic enzyme defects. Elastofibroma must be differentiated from other diseases that cause soft tissue tumor such as: spindle cell lipoma, nuchal-type fibroma, and fibromatosis colli. Elastofibroma may also be diagnosed using biopsy and histochemistry. Surgery is the mainstay of therapy for elastofibroma.

Pathophysiology

  • Elastofibroma, also called elastofibroma dorsi, is an ill-defined fibroelastic tumor-like condition made up of enlarged and irregular elastic fibers. [1] [2]
  • The tumor develops very specifically in the subscapular or infrascapular area, deep to the muscle, and can be attached to periosteum of ribs. It is usually between the shoulder blade and the lower neck, with rare tumors reported in the chest wall. [1] [3] [2]
  • The genetic mutation in has been associated alterations of short arm of chromosome 1 with the development of elastofibroma.
  • On gross pathology, ill defined, nonencapsulated, rubbery, and firm, white lesion with interspersed fat are characteristic findings of elastofibroma.
  • On microscopic histopathological analysis, heavy dense bands of collagenous tissue dissected by fat and abnormal elastic fibers are characteristic findings of elastofibroma. The elastic fibers are often quite large and are easily identified. The elastic fibers are coarse, thick, and darkly eosinophilic, often fragmented into globules, creating a "string of pearls" or "pipe cleaner" appearance. Degeneration will cause the elastic fibers to appear as globules with a serrated or prickled edge.

Causes

Differentiating Elastofibroma from other Diseases

  • Elastofibroma must be differentiated from other diseases that cause soft tissue tumor such as:
  • Spindle cell lipoma
  • Nuchal fibroma
  • Fibromatosis colli

Epidemiology and Demographics

  • Elastoblastoma is a very rare disease.

Age

  • Elastofibroma is more commonly observed among patients aged more than 50 years old.

Gender

  • Females are more commonly affected with elastofibroma than males.
  • The female to male ratio is approximately 5:1.

Race

  • Elastofibroma usually reported more in individuals of the Japanese race.

Risk Factors

  • Common risk factor in the development of elastofibroma is trauma.

Diagnosis

Symptoms

  • Symptoms of elastofibroma may include the following:
  • Swelling
  • Pain

Physical Examination

  • Patients with elastofibroma usually appear normal.
  • Physical examination may be remarkable for:
  • Slow growing, deep-seated, firm mass, often presenting bilaterally
  • Tenderness

Other Diagnostic Studies

  • Elastofibroma may also be diagnosed using biopsy and histochemistry.

Histochemistry

Treatment

Surgery

  • Surgery is the mainstay of therapy for elastofibroma.
