Chest Wall Intramuscular Myxoma : A Rare Tumor

Area of Science:

• Oncology
• Pathology
• Radiology

Background:

• Intramuscular myxomas are uncommon benign soft-tissue neoplasms.
• While typically found in the myocardium or large muscles of extremities and thighs, they can occur elsewhere.
• Chest wall localization is exceptionally rare.

Purpose of the Study:

• To report an extremely rare case of intramuscular myxoma in the chest wall.
• To discuss the diagnostic challenges and differential diagnoses for this rare tumor.
• To contribute to the literature on extracardiac myxomas.

Main Methods:

• Case report of a 68-year-old patient.
• Review of clinical presentation, imaging findings, and histopathological analysis.
• Discussion of differential diagnoses including sarcomas, lipomas, hematomas, and desmoid tumors.

Main Results:

• A confirmed diagnosis of intramuscular myxoma in the chest wall.
• Highlighting the rarity of this specific localization.
• Emphasizing the importance of accurate differentiation from malignant and other benign soft-tissue tumors.

Conclusions:

• Intramuscular myxomas, though rare, can occur in unusual locations like the chest wall.
• Accurate preoperative diagnosis is crucial due to potential confusion with more aggressive lesions.
• This case underscores the need for vigilance in evaluating soft-tissue masses.
