University Medical Center presented a case of gray zone lymphoma. Mediastinal gray zone lymphoma follows a more aggressive clinical course and carries a worse prognosis than both cHL and PMBCL.20 Some studies19 have suggested that more aggressive treatment, similar to that of conventional DLBCL, may be of benefit, while others22 have suggested that a therapeutic regimen more similar to that of cHL may be beneficial. O'Malley DP(1), Fedoriw Y, Weiss LM. with gray zone lymphoma were treated with the R-CHOP regimen because all had been previously diagnosed with DLBCL; however, the diagnosis was revised to gray zone lymphoma after review at the consensus meeting.

Modern Pathology. Gray zone lymphoma is a rare type of lymphoma, cancer of a part of the immune system called the lymph system.It is called "gray zone" lymphoma because it has features intermediate between classical Hodgkin lymphoma and diffuse large B-cell lymphoma (DLBCL), but cannot be assigned specifically to either type. It is extremely difficult to identifiy in some cases, and misdiagnsosis can greatly complicate treatment and lower outcome. As your excellent advice notes, pathology is everything in lymphoma.

The diagnosis of B-cell lymphoma, unclassifiable, with features intermediate between diffuse large B-cell lymphoma (DLBCL) and classical Hodgkin’s lymphoma (cHL), also referred to as grey zone lymphoma (GZL), is a challenging diagnosis. Recent evidence has demonstrated that misclassification can have significant therapeutic implications, particularly in the frontline setting. Twenty-one MGZL cases were identified over a 20-year period.

Dr. hopes this chemo will shrink tumor by at least 50% , then he will need donor for stem cell transplant. Mediastinal gray zone lymphoma, B-cell lymphomas with intermediate features between classical Hodgkin lymphoma and primary mediastinal B-cell lymphoma, have not been well described in the literature.
