B cell lymphoma

lymphoma, B cell

A malignant tumour found predominantly within the orbit and conjunctiva. Orbital lymphomas are the most common form of ocular lymphomas and cause proptosis and diplopia. They affect mainly adults and are primarily of the B cell/non-Hodgkin's type. Conjunctival lymphomas, also mainly of the B cell/non-Hodgkin's type, are seen in approximately 10% of systemic lymphoma patients. Clinically, conjunctival lymphomas appear salmon-pink in colour and have flat and smooth surfaces. There are several types of B cell lymphoma, one of them being Burkitt's lymphoma. Treatment is by radiotherapy.

A lymphoma which demonstrates transitional morphologic and immunophenotypic features between classical Hodgkin's lymphoma (CHL) and large B-cell lymphoma (diffuse large B cell lymphoma and Burkitt's lymphoma), mostly presenting with a mediastinal but occasionally with a peripheral lymph node disease is termed as grey zone lymphoma (GZL) as shown in figure 2.1,2 The terms "gray zone or grey zone or unclassifiable or indeterminate or mediastinal grey zone lymphoma (MGZL)" are synonymous and are used interchangeably.3,4 The outcome of these cases may differ from DLBCL and CHL.5 These lymphomas may show three types of features:
