Grey Zone Lymphomas: Lymphomas with Intermediate Features

Grey Zone Lymphomas: Lymphomas with Intermediate Features

The current classification of lymphoid neoplasms is based on clinical information, morphology, immunophenotype, and molecular genetic characteristics. Despite technical and scientific progress, some aggressive B-cell lymphomas with features overlapping between two different types of lymphomas remain difficult to classify. The updated 2008 World Health Organization (WHO) classification of Tumour...

Hodgkin’s lymphoma and Grey-zone lymphomas

Non-MALT marginal zone lymphomas.

The concept of marginal zone B-cell lymphomas was developed in the 1990s for lymphomas whose cells originate from B lymphocytes normally present in a distinct anatomical location, the so-called ‘marginal zone’ (MZ). MZ has been described in the lymphoid organs—spleen and lymph nodes—and in nonlymphoid organs—mucosa-associated lymphoid tissue (MALT) or non-mucosal tissue such as skin, orbit and ...

Pediatric Non Hodgkin’s Lymphomas

Clinical, pathological and genetic features of primary mediastinal large B-cell lymphomas and mediastinal gray zone lymphomas in children.

UNLABELLED Background Primary mediastinal large B-cell lymphoma is a rare lymphoma accounting for no more than 3% of all B-cell lymphomas in children and adolescents. However, patients in this young age group with this lymphoma have the shortest event-free survival of patients with any B-cell lymphoma under current standard chemotherapy protocols. Lymphomas with features intermediate between pr...
