What is Monocytoid B cell hyperplasia?

Monocytoid B-cell lymphoma (MBCL) is a newly recognized. malignant lymphoma that shares clinical and pathologic features. with other low-grade B-cell neoplasms, especially small lym- phocytic lymphoma and hairy cell leukemia.

What is Interfollicular hyperplasia?

Interfollicular Hodgkin’s Disease is characterised by reactive follicular hyperplasia with involvement of the interfollicular area of lymph node by Hodgkin’s lymphoma. It represents a peculiar pattern of focal involvement of lymph node and does not constitute a classical subtype.

What causes lymphoid hyperplasia in throat?

Lymphoid papillary hyperplasia may be the result of the excessively persistentantigenic stimulation on the tonsils.

What are Monocytoid cells?

Introduction. Monocytoid B cells are an as yet enigmatic B cell sub- population, localized in the perisinusoidal area of the lymph node. These cells are morphologically character- ized by round to oval nuclei and more abundant cytoplasm, features that are more typical for monocyte- derived cells, hence their name.

What is the treatment for follicular hyperplasia?

Proceeding a tissue sample, an effective treatment for follicular hyperplasia is surgical removal of the lesion after an initial conformation of the disease based on the patients biopsy results.

How do you treat follicular hyperplasia?

How are monocytoid B cells different from marginal zone B cells?

Benign monocytoid B-cells are a peculiar subset of B-cells. They are closely related to marginal zone B-lymphocytes, show cytological diversity and may be recognized in a variety of reactive lymph node conditions.

Can a monocytoid B cell be positive for Bcl-2?

Immunohistologically, both types of benign monocytoid B-cells were negative for bcl-2 protein expression, which was in contrast to the bcl-2 positive reaction in marginal zone B-lymphocytes and their neoplastic counterpart in monocytoid B-cell lymphoma.

How often are monocytoid B cells found in lymph nodes?

A monocytoid B-cell reaction was identified in 46 (15%) cases and could be cytologically subclassified into two groups: 31 (67%) cases with common-type cells and 15 (33%) cases with large, transformed cells, according to the description by Plank et al. [19].
