    Summary
    This summary is machine-generated.

    A painless lump near the shoulder blade was initially suspected to be cancer. However, imaging and biopsy confirmed it was an elastofibroma, a benign tumor, highlighting the need for biopsy in such cases.

    Area of Science:

    • Orthopedic Surgery
    • Radiology
    • Pathology

    Background:

    • Elastofibromas are rare, benign soft-tissue tumors typically found in the subscapular or periscapular regions.
    • They are often asymptomatic and discovered incidentally on imaging studies.
    • Distinguishing elastofibromas from malignant neoplasms can be challenging based on imaging alone.

    Observation:

    • A 68-year-old male presented with a painless, nontender mass in the right infrascapular area.
    • Computed tomography (CT) revealed a soft-tissue mass attached to the scapula with muscular displacement, and a similar smaller mass on the contralateral side.
    • The imaging characteristics were initially concerning for infiltrating malignancy.

    Findings:

    • Pathologic examination of the mass revealed features characteristic of elastofibroma.

  • The findings underscore the importance of histopathological evaluation for accurate diagnosis.
  • Elastofibroma dorsi is a benign proliferation of elastic fibers.

    • Implications:

    • Biopsy is crucial in cases with imaging suggestive of malignancy to rule out sarcoma.
    • Accurate diagnosis prevents unnecessary aggressive treatment for benign conditions like elastofibroma.
    • This case emphasizes the role of multidisciplinary evaluation in soft-tissue tumor diagnosis.
