• Locations: 0 countries
• Sites: N/A

Brief Summary

This study aims to retrospectively evaluate patients who underwent surgical treatment for elastofibroma dorsi, a rare benign tumor typically located in the subscapular region of the chest wall. The study will analyze demographic and clinical features, risk factors, diagnostic imaging methods, postoperative complications, and recurrence rates. By identifying potential predictors of complications and recurrence, the study hopes to contribute to the understanding and management of this silent and often incidental lesion.

Study Arms (1)

Surgically Treated Elastofibroma Dorsi Patients

This cohort includes patients diagnosed with elastofibroma dorsi who underwent surgical resection between 2010 and 2025. Patients were retrospectively evaluated for demographic characteristics, clinical features, diagnostic methods, surgical findings, postoperative complications, and recurrence during follow-up.

Other: Retrospective Medical Record Review

Interventions

Retrospective Medical Record Review OTHER

Review of archived medical, surgical, and radiological records of patients diagnosed with elastofibroma dorsi and treated surgically. No active intervention was administered as part of the study.

Study Population

The study population consists of adult patients (aged 18 and older) who were diagnosed with elastofibroma dorsi and underwent surgical resection at a single tertiary care center between 2010 and 2025. All included patients had histopathologically confirmed diagnoses and at least one month of postoperative follow-up available in hospital records.

You may qualify if:

• Patients who underwent surgical treatment for elastofibroma dorsi
• Histopathological confirmation of the diagnosis
• Minimum of 1-month postoperative follow-up available
• Age 18 years or older
• Accessible medical and imaging records in hospital archives
• Signed informed consent available in patient records (if applicable)

You may not qualify if:

• Patients diagnosed with elastofibroma dorsi but not treated surgically
• Cases without histopathological confirmation
• Incomplete or insufficient medical and radiological records
• Postoperative follow-up period less than 1 month
• Patients younger than 18 years
• Absence of documented informed consent (if applicable)
