Abstract Casestudy A 52-year-old female presented with night sweats, chills, anorexia, and weight loss. Computed tomography and positron emission tomography showed a soft tissue infiltration in the anterior mediastinum and hypermetabolic bilateral supraclavicular, mediastinal, right hilar, and left internal mammary lymph nodes. An anterior mediastinal mass resection and thymectomy was subsequently performed. Results Sections of the mediastinal mass showed Hodgkin/Reed-Sternberg cells (HRS) admixed with small lymphocytes, histiocytes, plasma cells, and eosinophils. The HRS cells are positive for CD30, CD15, and MUM1, faintly positive for PAX5, and negative for CD20, CD45, CD79a, and BCL6. The morphology and immunophenotype is diagnostic of nodular sclerosis classic Hodgkin lymphoma (CHL). Sections of the thymectomy specimen showed similar morphology, however, in an area that represents 10-20% of the specimen, there are nodular and diffuse lymphoid infiltrates consisting of small lymphocytes, histiocytes, and large atypical cells. The large atypical cells are positive for CD20, CD23, CD30, CD45, CD79a, BCL2, BCL6, MUM-1, and PAX5, and negative for CD1a, CD3, CD57, and Cyclin D1. The background small CD3-positive lymphocytes form a rosette around most of the large atypical cells. CD21 and CD23 stains highlight residual follicular structures. In situ hybridization for EBV-encoded RNA (EBER) is negative. The presence of residual follicular meshwork with an immunophenotype of large B cell lymphoma supports a diagnosis of a gray zone lymphoma (GZL). Overall, CHL is involving 80-90% and GZL is involving 10-20% of the thymic tissue. The patient was subsequently placed on ABVD chemotherapy and achieved remission. Conclusion An accurate diagnosis of GZL is challenging. GZL is a rare type of lymphoma with morphological features between CHL and diffuse large B-cell lymphoma (DLBCL). It is even rarer to encounter a CHL concurrently present with a GZL. The optimal therapeutic approach for cases with concurrent lymphoma diagnosed with CHL and GZL needs further investigation.

Gray zone lymphoma, also known as B-cell lymphoma, unclassifiable, with features intermediate between diffuse large B-cell lymphoma and classical Hodgkin lymphoma, is a rare malignancy with overlapping features of both diffuse large B-cell lymphoma and classical Hodgkin lymphoma. Most commonly mediastinal involvement is seen. Extranodal involvement is rare. In this case report, we present the case of a 59-year-old male who presented with stress-related left shoulder pain, ultimately diagnosed with gray zone lymphoma. The patient was treated with etoposide, prednisone, vincristine, cyclophosphamide, and doxorubicin-rituximab (EPOCH-R) regimen followed by consolidation radiotherapy resulting in complete response. We are highlighting this case as rare and atypical presentation of a rare disease.

Abstract Primary mediastinal (thymic) large B-cell lymphoma (PMBCL) is a subtype of diffuse large B-cell lymphoma (DLBCL). It commonly presents as a bulky lesion in the anterior-superior mediastinum with symptoms related to local invasion or compression. Microscopic examination typically shows infiltration of medium-large cells surrounded by collagen fibrosis. The neoplastic cells express B-cell markers, and CD30 often shows heterogeneous staining. Comparative genomic hybridization has identified gains in loci of 9p24 and 2p15 as well as Xp11.4-21 and Xq24-26. Amplification of REL and BCL11A at 2p as well as elevated expression of JAK2, PDL1, and PDL2 at 9p has been demonstrated. Nodular sclerosis classic Hodgkin lymphoma needs to be differentiated from PMBCL and cases with overlapped features have been described as mediastinal gray zone lymphoma. Primary mediastinal (thymic) large B-cell lymphoma carries a favorable prognosis in comparison to conventional DLBCL.
