Historical Perspective

• [Disease name] was first discovered by [scientist name], a [nationality + occupation], in [year] during/following [event].
• In [year], [gene] mutations were first identified in the pathogenesis of [disease name].
• In [year], the first [discovery] was developed by [scientist] to treat/diagnose [disease name].

Classification

• [Disease name] may be classified according to [classification method] into [number] subtypes/groups:

• [group1]
• [group2]
• [group3]

• Other variants of [disease name] include [disease subtype 1], [disease subtype 2], and [disease subtype 3].

Pathophysiology

• Elastofibroma, also called elastofibroma dorsi, is an ill-defined fibroelastic tumor-like condition made up of enlarged and irregular elastic fibers.
• 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. Because of degeneration, the elastic fibers will appear as globules with a serrated or "prickled" edge.

Causes

• Elastofibroma may be caused by either trauma, genetic mutation, or systemic enzyme defects.

Differentiating [disease name] from other Diseases

• Elastofibroma must be differentiated from other diseases that cause [clinical feature 1], [clinical feature 2], and [clinical feature 3], such as:

• Spindle cell lipoma
• nuchal-type 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 male.
• The female to male ratio is approximately 5:1.

Race

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

Risk Factors

• Common risk factors in the development of [disease name] are [risk factor 1], [risk factor 2], [risk factor 3], and [risk factor 4].

Natural History, Complications and Prognosis

• The majority of patients with [disease name] remain asymptomatic for [duration/years].
• Early clinical features include [manifestation 1], [manifestation 2], and [manifestation 3].
• If left untreated, [#%] of patients with [disease name] may progress to develop [manifestation 1], [manifestation 2], and [manifestation 3].
• Common complications of [disease name] include [complication 1], [complication 2], and [complication 3].
• Prognosis is generally [excellent/good/poor], and the [1/5/10year mortality/survival rate] of patients with [disease name] is approximately [#%].

Diagnosis

Diagnostic Criteria

• The diagnosis of [disease name] is made when at least [number] of the following [number] diagnostic criteria are met:

• [criterion 1]
• [criterion 2]
• [criterion 3]
• [criterion 4]

Symptoms

• [Disease name] is usually asymptomatic.

• [symptom 1]
• [symptom 2]
• [symptom 3]
• [symptom 4]
• [symptom 5]
• [symptom 6]

Physical Examination

• Patients with elastofibroma usually appear normal.
• Physical examination may be remarkable for:

• Slow growing, deep-seated, firm mass, often presenting bilaterally
• Tenderness

Laboratory Findings

• There are no specific laboratory findings associated with [disease name].
• A [positive/negative] [test name] is diagnostic of [disease name].
• An [elevated/reduced] concentration of [serum/blood/urinary/CSF/other] [lab test] is diagnostic of [disease name].
• Other laboratory findings consistent with the diagnosis of [disease name] include [abnormal test 1], [abnormal test 2], and [abnormal test 3].

Imaging Findings

• On CT, elastofibroma is characterized bypoorly circumscribed, heterogeneous soft tissue mass, with a signal intensity similar to skeletal muscle.
• On US, elastofibroma is characterized by multilayered pattern of hypoechoic linear areas of fat deposition intermixed with echogenic fibroelastic tissue.
• [Imaging study 2] may demonstrate [finding 1], [finding 2], and [finding 3].

Other Diagnostic Studies

• [Disease name] may also be diagnosed using [diagnostic study name].
