Papillary Dermis

Papillary Dermis

Dermis
The dermis might be considered the "core" of the integumentary system, as distinct from the epidermis and hypodermis. It contains blood and lymph vessels, nerves, and other structures, such as hair follicles and sweat glands. The dermis is made of two layers of connective tissue that comprise an interconnected mesh of elastin and collagenous fibers, produced by fibroblasts.
Papillary Layer
The papillary layer is made of loose, areolar connective tissue, which means the collagen and...

Elastin is Responsible for Tissue Elasticity

Elastin is Responsible for Tissue Elasticity

Elastic fiber contains the protein elastin along with lesser amounts of other proteins and glycoproteins. The main property of elastin is that it will return to its original shape after being stretched or compressed. Elastic fibers are prominent in elastic tissues found in skin and the elastic ligaments of the vertebral column.
Ligaments and tendons are made of dense regular connective tissue, but in ligaments not all fibers are parallel. Dense regular elastic tissue contains elastin fibers and...

Summary

Elastofibroma dorsi is a rare benign pseudotumor often mistaken for malignancy. Surgical excision is effective for symptomatic cases with no reported recurrences.

Area of Science:

Orthopaedic Oncology
Soft Tissue Pathology

Background:

Elastofibroma dorsi is an uncommon benign soft tissue pseudotumor.
Typically located deep to periscapular muscles, it can be mistaken for malignant tumors due to size and location.
Often presents with swelling, pain, and discomfort in patients over 50.

Purpose of the Study:

To highlight the clinical and radiological presentation of elastofibroma dorsi.
To increase awareness and inform management strategies for this rare condition.

Main Methods:

Retrospective review of an orthopaedic oncology database (17,500 patients).
Identified 15 cases of elastofibroma dorsi.
Diagnostic methods included MRI, excision biopsy, trucut biopsy, and open biopsy.

Main Results:

15 patients diagnosed with elastofibroma dorsi (12 males, 3 females; mean age 68.4 years).
Eight symptomatic patients underwent lesion excision.
No recurrences were reported post-excision.

Conclusions:

Elastofibroma dorsi is a rare benign tumor that can mimic malignancy.
Awareness of its presentation is crucial for accurate diagnosis and management.
Surgical excision is a safe and effective treatment for symptomatic lesions.
