A rare desmoid tumor arising from the manubrium

Area of Science:

• Oncology
• Surgical Pathology
• Radiology

Background:

• Desmoid tumors are rare neoplasms originating from connective tissues.
• While commonly found in the abdomen, sternal manubrium involvement is exceptionally rare.
• These tumors can present diagnostic challenges due to their variable appearance.

Observation:

• A case of a desmoid tumor in the sternal manubrium is presented.
• The tumor exhibited radiological and metabolic characteristics suggestive of a malignant lesion.
• This presentation mimicked aggressive bone tumors, complicating the initial diagnosis.

Findings:

• The sternal manubrium desmoid tumor was successfully treated with surgical resection.
• Reconstruction of the sternal defect was achieved using autogenous rib grafts.
• Histopathological examination confirmed the diagnosis of desmoid tumor.

Implications:

• This case expands the known spectrum of desmoid tumor presentation.
• It underscores the importance of considering benign entities in the differential diagnosis of sternal masses.
• Successful surgical management demonstrates a viable treatment option for rare sternal desmoid tumors.
