Cell surface markers on lymphoid cells from Warthin's tumors
Cancer
|August 1, 1979
Summary
Warthin's tumors contain T- and B-lymphocytes, similar to normal lymph nodes. This suggests the lymphoid cells in Warthin's tumors originate from pre-existing lymph node tissue.
Area of Science:
- Immunology
- Oncology
- Pathology
Background:
- Warthin's tumors are benign salivary gland neoplasms.
- The cellular composition of Warthin's tumors, particularly the lymphoid infiltrate, is not fully understood.
Purpose of the Study:
- To characterize the T- and B-cell populations within Warthin's tumors.
- To compare the lymphoid infiltrate in Warthin's tumors to that of normal lymph nodes.
Main Methods:
- Analysis of lymphoid cell suspensions from two Warthin's tumors.
- Immunophenotyping using T- and B-cell markers.
- Assessment of B-lymphocyte surface immunoglobulin distribution.
Main Results:
- Warthin's tumors predominantly contained T-lymphocytes with a smaller proportion of B-lymphocytes.
- B-lymphocytes exhibited a polyclonal surface immunoglobulin distribution.
- The lymphoid cell profile was comparable to that of normal or reactive lymph nodes.
Conclusions:
- The lymphoid component in Warthin's tumors mirrors that of normal lymph nodes.
- Findings support the hypothesis that Warthin's tumors incorporate pre-existing lymph node tissue.
