Paraskeletal plasmacytoma presenting as a chest wall mass

Area of Science:

• Hematology
• Oncology
• Pathology

Background:

• Multiple myeloma is a plasma cell malignancy.
• Extramedullary involvement, while uncommon, signifies advanced disease.
• Plasma cell tumors can arise outside the bone marrow.

Observation:

• A 60-year-old man presented with a chest wall mass.
• The mass was identified as a paraskeletal plasmacytoma.
• This represents an unusual presentation of extramedullary disease.

Findings:

• Paraskeletal plasmacytoma can manifest as a soft tissue mass.
• Direct extension or hematogenous spread can cause extramedullary lesions.
• This case underscores the diverse clinical presentations of multiple myeloma.

Implications:

• Early recognition of extramedullary disease is crucial for patient management.
• Chest wall masses should be evaluated for potential plasma cell origin.
• Understanding rare presentations aids in comprehensive oncological care.
