Epibulbar IgA plasmacytoma occurring in multiple myeloma
Archives of Ophthalmology (Chicago, Ill. : 1960)
|March 1, 1982
Summary
This study details a rare case of multiple myeloma with unusual eye and mucosal surface involvement. Ocular and tumor regression occurred with systemic treatment and local irradiation.
Area of Science:
- Ophthalmology
- Oncology
- Immunology
Background:
- Multiple myeloma is a plasma cell malignancy.
- Ocular manifestations are uncommon but can be severe.
- IgA myeloma has distinct clinical features.
Observation:
- A 51-year-old man presented with exudative retinal detachments and epibulbar plasmacytomas.
- The patient had a history of IgA myeloma diagnosed at age 37 with a 14-year disease course.
- Epibulbar, gastrointestinal, and prostate involvement were noted.
Findings:
- Ophthalmic findings resolved with systemic myeloma treatment.
- Epibulbar plasmacytomas showed rapid regression following local irradiation.
- The combination of early onset, prolonged course, IgA M protein, and epibulbar involvement is highly unusual for multiple myeloma.
Implications:
- The findings suggest a potential homing mechanism of IgA-committed cells to mucosal surfaces.
- This case highlights the importance of considering unusual presentations in multiple myeloma.
- Understanding these mechanisms may inform future therapeutic strategies for IgA myeloma.
