Lymphoma is a type of cancer of the cells of the immune system. Lymphomas are broadly divided into two groups: Hodgkin lymphomas (Hodgkin’s disease) and non-Hodgkin lymphoma, or NHL. Within these categories there are many different subtypes

Because these lymphomas are treated differently, the optimal therapy for gray zone lymphoma is unclear. Grey zone lymphoma (GZL) is a very rare aggressive (fast-growing) B-cell non-Hodgkin lymphoma that has characteristics of both Hodgkin lymphoma (HL) and a type of diffuse large B-cell lymphoma, called primary mediastinal B-cell lymphoma (PMBCL), making it very difficult to diagnose and decide upon treatment options. Since grey zone lymphoma (GZL) was originally included in the 2008 World Health Organization classification as a B-cell lymphoma unclassifiable with features intermediate between diffuse large B-cell lymphoma (DLBCL) and classical Hodgkin lymphoma (cHL), new biological and clinical knowledge have been learned. Grey zone lymphoma Rarely, a lymphoma has features of both classical Hodgkin lymphoma and diffuse large B-cell lymphoma (DLBCL), particularly a type of DLBCL called ‘ primary mediastinal B-cell lymphoma (PMBL) ’. Gray zone lymphoma, often presenting as large tumors in the mediastinum, is a type of lymphoma that is characterized by having cellular features of both classic Hodgkin's lymphomas (cHL) and large B-cell lymphomas. Nodular sclerosis Hodgkin lymphoma (NSHL) and primary mediastinal B-cell lymphoma (PMBL) are the common types, whereas mediastinal gray-zone lymphoma (MGZL) is extremely rare and has pathological features intermediate between NSHL and PMBL. Keywords: Grey/gray zone lymphoma, classical Hodgkin lymphoma, diffuse large B-cell lymphoma, prognosis, treatment.
