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.
