[Plasmacytoma of the orbit]
Summary
A plasma-cell tumor caused exophthalmos in a 69-year-old woman, suggesting orbital myelomatosis. Diagnosis considered solitary myeloma and extramedullary plasmacytoma.
Area of Science:
- Ophthalmology
- Oncology
- Pathology
Background:
- Orbital tumors can present with proptosis, necessitating a thorough differential diagnosis.
- Plasma-cell tumors are rare orbital neoplasms with varied presentations.
Observation:
- A 69-year-old female presented with left eye exophthalmos.
- Clinical examination and imaging (axial CT, ultrasonography) were performed.
Findings:
- The exophthalmos was attributed to a plasma-cell tumor.
- Differential diagnoses included myelomatosis, solitary myeloma of bone, and extramedullary plasmacytoma.
- Findings suggested orbital involvement consistent with myelomatosis.
Implications:
- This case highlights the importance of considering myelomatosis in orbital plasma-cell tumors.
- Accurate diagnosis is crucial for appropriate management of orbital plasma-cell neoplasms.
- Multimodality imaging aids in differentiating orbital tumor types.
