Macroscopic ovarian involvement in murine plasmacytoma

Area of Science:

• Oncology
• Immunology
• Mouse Models

Background:

• Plasmacytoma is a malignant tumor of plasma cells.
• BALB/c/Se/Si mice are a common model for plasmacytoma research.
• Ovarian involvement in plasmacytoma has not been previously documented.

Purpose of the Study:

• To investigate the histological effects of plasmacytoma LPC/I on the ovaries of BALB/c/Se/Si mice.
• To determine the incidence and gross pathology of ovarian changes associated with plasmacytoma.

Main Methods:

• BALB/c/Se/Si mice were induced with plasmacytoma LPC/I.
• Ovaries were examined histologically for plasmacellular proliferation.
• Macroscopical assessment of ovarian changes was performed.

Main Results:

• Histological plasmacellular proliferation was observed in all examined ovaries.
• Macroscopical expression of this proliferation was evident in 30% of the mice.
• This represents a novel observation in plasmacytoma-bearing mice.

Conclusions:

• Plasmacytoma LPC/I induces significant ovarian pathology in BALB/c/Se/Si mice.
• The observed plasmacellular proliferation can reach macroscopical levels.
• This study highlights an uncharacterized effect of plasmacytoma on reproductive organs.
