Summary
A solitary lytic lesion in a 67-year-old man was diagnosed as plasmacytoma after MR imaging and biopsy. This case highlights key clinical, imaging, and histologic features of this rare neoplastic condition.
Area of Science:
- Oncology
- Radiology
- Pathology
Background:
- Plasmacytoma is a rare neoplastic proliferation of plasma cells.
- It can occur as a solitary lesion or as part of multiple myeloma.
- Solitary plasmacytoma of bone requires accurate diagnosis for appropriate management.
Observation:
- A 67-year-old male presented with a solitary lytic lesion in the proximal humerus.
- Magnetic resonance (MR) imaging revealed characteristic features of the lesion.
- A biopsy was performed for definitive diagnosis.
Findings:
- Histologic examination confirmed the diagnosis of plasmacytoma.
- The lesion demonstrated specific imaging characteristics on MR.
- Clinical presentation and diagnostic workup are detailed.
Implications:
- Accurate diagnosis of solitary plasmacytoma is crucial for treatment planning.
- This case contributes to understanding the presentation of plasmacytoma.
- Early detection and management can impact patient outcomes.

01:31Muscles that Move the Arm
Nine muscles are involved in arm movements. Two of these, the pectoralis major and latissimus dorsi, originate from the axial skeleton and are called axial muscles. The other seven originate from the scapula and are called the scapular muscles.
The pectoralis major has two origins. Its clavicular head originates on the medial half of the clavicle. In contrast, the sternocostal head originates on the costal cartilages of ribs 1-6, the sternum, and the aponeurosis of the external oblique of the...

01:31Hybridoma Technology
Hybridoma technology is used for the large-scale production of monoclonal antibodies. Monoclonal antibodies bind to only a single antigenic determinant or epitope. Such antibodies are used in research, diagnostics, and disease therapy. The hybridoma technology established in 1975 by Georges Köhler and Cesar Milstein was awarded the Nobel Prize in Medicine in 1984 for revolutionizing research and therapy.
