We analyse this rare pseudotumour with few case reports in the orthopaedic literature. Elastofibroma dorsi is an uncommon benign soft tissue pseudotumour usually located at the lower pole of the scapula. This study is a clinical assessment of 5 patients. All the patients had their diagnosis based on clinical and MRI findings and had excision biopsy. The patients were followed for a mean period of 24 months. No patient had residual symptoms. We have only one recurrence. Surgical excision is recommended when it causes functional disability, compression symptoms, an asymmetric outline of the chest wall, or when it is more than 5 cm in diameter. Pre-operative tissue diagnosis is not necessary in most cases. Despite its rarity, the elastofibroma dorsi should always be suspected with the emergence of a swelling in the subscapularis, especially in females and in old age.

Introduction And Importance: Elastofibroma dorsi is a rare benign soft tissue lesion primarily located in the subscapular region. This distinctive lesion, with its unique radiological and histological features, poses diagnostic challenges due to its subtle presentation and overlap with other conditions.
Case Presentation: A 48-year-old man, manual laborer with an unremarkable medical history presented with a progressively enlarging mass below the right scapula over two years.

Article Synopsis
- Angiomatoid fibrous histiocytoma (AFH) is a rare, low-grade malignant soft-tissue tumor commonly found in children and young adults, often misdiagnosed due to its atypical presentation.
- A case involving a 12-year-old boy with a painless mass on his back led to a CT scan revealing a sizable soft tissue mass, which was completely excised.
- Pathological analysis confirmed AFH with specific diagnostic features, and after five years of follow-up, there were no signs of recurrence, marking a successful outcome.

Article Synopsis
- Elastofibroma dorsi is a rare, non-cancerous soft-tissue tumor commonly found in elderly women, usually causing no symptoms but potentially leading to discomfort and pain in the shoulder.
- A case study of a 78-year-old man revealed an asymptomatic mass in the subscapular region, diagnosed and confirmed via MRI, and successfully removed through surgery with no complications.
- The findings highlight the importance of imaging and histopathological analysis to differentiate elastofibroma dorsi from malignant conditions, along with a call for further research to understand its development mechanisms.

Article Synopsis
- Elastofibroma dorsi (ED) is a rare, benign tumor in the upper back area, primarily affecting women, and this study analyzed the clinical outcomes and surgical management of 20 patients with ED.
- The majority of patients experienced swelling, with half showing unilateral involvement, and all underwent standard surgical procedures without any recurrences noted during follow-ups ranging from 6 to 53 months.
- The findings support that while ED is uncommon, it should be considered in cases of back swelling, and surgery is a safe treatment option following proper diagnosis.
Imaging Diagnosis of Thoracic Elastofibroma Dorsi.

From the Division of Thoracic Imaging, Brigham and Women's Hospital, Boston, Massachusetts, USA.
Article Synopsis
- Elastofibroma dorsi (ED) is a rare benign tumor often found accidentally during thoracic imaging, and this study aims to identify its typical imaging features and assess the risk of it being confused with cancer.
- The researchers reviewed 409 suspected ED cases over 12 years, focusing on imaging techniques like CT and MRI, noting key characteristics such as tumor location and presence of fat within the lesions.
- Findings showed that ED typically appears near the scapular tip and deep to the serratus anterior, with a significant percentage of cases showing interspersed fat, allowing for strong diagnostic confidence which reduces the need for additional testing.
