This study presents a unique case of follicular lymphoma with features of mantle cell lymphoma, suggesting a potential link and varied development pathways for small B-cell lymphomas.
Area of Science:
- Hematology
- Oncology
- Pathology
Background:
- Follicular lymphoma (FL) originates from germinal center B cells and typically lacks mantle zones.
- Transformation to aggressive lymphomas is known, but FL's connection to mantle cell lymphoma (MCL) is primarily seen in composite lymphomas.
Observation:
- A lymph node case exhibited both FL and MCL-like features within the same node.
- Immunohistochemistry revealed distinct cell populations and markers (CD20, CD10, BCL2, BCL6, cyclin D1, CD5, SOX11, Ki67, CD21) in different areas.
- Both components shared BCL2 rearrangement, SOX11 expression, and an identical clonal band, but lacked t(11:14).
Findings:
- The case demonstrates heterogeneous development in small B-cell lymphomas.
- It suggests a possible differentiation regression, where one lymphoma type may evolve from another.
Implications:
- This finding expands our understanding of lymphoma heterogeneity and potential developmental pathways.
- It highlights the importance of comprehensive analysis in diagnosing lymphomas with overlapping features.
- Further research into these differentiation pathways could inform therapeutic strategies.

Lymphoid Cells and Tissues
Lymphoid cells consist of various types of immune system cells. These include B and T lymphocytes, which are responsible for producing antibodies and killing infected cells, respectively. Dendritic cells act as messengers between the innate and adaptive...
Secondary Lymphoid Organs
The spleen is a vital organ in the lymphatic system, nestled in the upper left side of the abdomen. It is composed of two primary regions: the red pulp and the white pulp, each having distinct functions. The red pulp performs a significant role in blood filtration. It efficiently purges the blood of old or damaged red blood cells and...
Detailed Structure and Function of Lymph Nodes
From a histological perspective, lymph nodes can be split into two main areas: the superficial cortex and the deep medulla. The outer cortex is populated by dendritic cells, macrophages, and B lymphocytes, which are densely packed into follicles. When these B-lymphocytes are presented...
