What is the prevalence of Elastofibroma Dorsi?

Elastofibroma dorsi is a rare, benign soft-tissue tumor typically found beneath the shoulder blade, with autopsy studies suggesting a prevalence ranging from 0.5% to 2% in elderly populations. While once thought to be extremely rare, elastofibroma dorsi is likely underdiagnosed due to its often asymptomatic nature and slow growth.

Is the prevalence of Elastofibroma dorsi accurately known?

The true prevalence of elastofibroma dorsi remains difficult to determine because many individuals remain asymptomatic and never seek clinical evaluation. While clinical reports often label it as "rare," autopsy studies conducted by researchers like Jarvi and Saxen have identified the prevalence of elastofibroma dorsi to be as high as 2% in older individuals, suggesting that it is significantly more common than clinical diagnostic rates imply.

Who is most likely to develop Elastofibroma dorsi?

Elastofibroma dorsi exhibits distinct demographic patterns regarding age and gender:

• Age of Onset: It is primarily a condition of the elderly, with most diagnoses occurring in patients over the age of 55. It is exceedingly rare in pediatric populations.


• Gender Distribution: Studies consistently show a female predilection, with a female-to-male ratio often cited between 5:1 and 13:1.


• Geographic/Ethnic Factors: While cases of elastofibroma dorsi are reported globally, some literature suggests a higher frequency in specific populations, such as in Okinawa, Japan, though this may be linked to specific environmental or repetitive physical labor factors.

How does the DiseaseMaps community experience compare?

This community data provides a vital, real-world perspective that complements clinical statistics, highlighting the patient journey from the initial discovery of a subscapular mass to the management of potential discomfort or mobility issues.

Next steps

• Consult an orthopedic oncologist or a radiologist if you have discovered a persistent mass beneath your scapula.


• Request imaging, such as an MRI or CT scan, as these are the gold standards for diagnosing elastofibroma dorsi.
