B-cell Lymphoma, Unclassifiable, with Features Intermediate Diffuse Large B-cell Lymphoma are cancers that begin in B-cells, a type of white blood cell that makes antibodies. These cancers grow in the lymph nodes, bone marrow, blood, spleen, or other organs. Some forms grow slowly for years (called indolent). Others grow fast and need urgent treatment (called aggressive). Doctors diagnose them with blood tests, imaging, and a biopsy of a lymph node or bone marrow. Treatment can include watching closely without drugs (if slow), targeted medicines, chemotherapy, radiation, antibody therapy, cellular therapy (CAR-T), and sometimes stem-cell transplant. The exact plan depends on the cancer type, stage, symptoms, and your overall health. National Cancer Institute+2National Cancer Institute+2
B-cell lymphoma, unclassifiable, with features intermediate between diffuse large B-cell lymphoma and classical Hodgkin lymphoma is a rare blood cancer. Doctors used to call it by this long name because the cells look and act like a “mix” of two other cancers: diffuse large B-cell lymphoma (DLBCL) and classical Hodgkin lymphoma (cHL). Today, experts understand that most cases happen in the mediastinum (the area in the middle of the chest). So the modern name is often mediastinal gray zone lymphoma (MGZL). “Gray zone” means the cancer sits between two better-known types. It can show warning signs and lab results that look like both DLBCL and Hodgkin lymphoma. It grows fast, but many people can be treated successfully. An expert blood-cancer pathologist should confirm the diagnosis because it is tricky. ASH Publications+3Nature+3PMC+3
This cancer most often starts as a mass behind the breastbone. It may press on nearby structures like the windpipe and major veins. People can feel chest pressure, cough, trouble breathing, or swelling of the face and neck from vein blockage. Under the microscope, the tumor cells show features that overlap with primary mediastinal large B-cell lymphoma (PMBCL) and nodular sclerosis classical Hodgkin lymphoma. Special staining tests can show both B-cell markers and Hodgkin-type markers at the same time. That “mixed” pattern is a key clue. PMC+2Nature+2
In the latest World Health Organization (WHO) and International Consensus classifications, the old, long label has been replaced by mediastinal gray-zone lymphoma, reflecting that these tumors form a single biologic family with a spectrum from cHL to PMBCL. That change helps doctors use clearer words and design better studies. Nature+2ScienceDirect+2

Gray-zone lymphoma (GZL) — short form commonly used in clinics and studies. ASH Publications+1
B-cell lymphoma, unclassifiable, with features intermediate between DLBCL and classical Hodgkin lymphoma — the older WHO term that you may still see in older reports or charts. PMC
Common B-cell cancers include: diffuse large B-cell lymphoma (DLBCL), follicular lymphoma, mantle cell lymphoma, marginal zone lymphoma, Waldenström macroglobulinemia, Burkitt lymphoma, B-cell acute lymphoblastic leukemia/lymphoma, and chronic lymphocytic leukemia/small lymphocytic lymphoma (CLL/SLL). Doctors group them by how fast they grow (indolent vs aggressive) and by unique markers on the cells (like CD19 or CD20). Modern classifications (WHO 5th edition/2022–2024 updates) use genetics and cell features to label each disease more precisely, which guides therapy. Modern Pathology+1
Types
Doctors mostly group this cancer by where it starts and by how it looks in tests:
Mediastinal gray-zone lymphoma (typical form).
Starts in the chest. Shares features with PMBCL and nodular sclerosis classical Hodgkin lymphoma. This is the form recognized in current classifications. NatureNon-mediastinal gray-zone–like cases (uncommon, debated).
Rare reports describe similar “gray” features outside the chest (like neck or abdomen). Many experts think these are not classic GZL and may belong to other categories after careful review. A specialist review is advised. nccn.org+1Pathology-based spectrums.
Some tumors look more like PMBCL but with Hodgkin-type markers; others look more like classical Hodgkin lymphoma but with stronger B-cell features. Both sit on the same spectrum. PMC+1
Causes and risk factors
No single cause is known. Most people have no clear risk they could have changed. Scientists think several things may raise risk or help the cancer form:
Shared origin with PMBCL and cHL.
Genetic and epigenetic studies show MGZL sits between these two diseases, suggesting a common cell of origin in the thymic/mediastinal B-cell pathway. NatureAbnormal genes in tumor cells.
Changes in chromosome regions that control growth and immune signals (e.g., 9p24.1 with PD-L1/PD-L2) are reported and may overlap with PMBCL/cHL. NatureImmune-escape pathways.
Overactive PD-1/PD-L1 axis helps tumor cells hide from the immune system, similar to cHL and PMBCL. NatureMediastinal B-cell development issues.
Problems during the maturation of B cells in the thymic/mediastinal environment may lead to malignant change. (Inference based on location and biology.) PMCInflammation-driven signals.
Strong inflammatory microenvironments, like in cHL, may support tumor survival. PMCJAK/STAT pathway activation.
Some gray-zone tumors show signaling patterns that push growth and survival. NatureNF-κB pathway activation.
Pathways that drive cell survival in PMBCL and cHL can also be active in MGZL. NatureCopy-number changes.
Gains/losses of chromosome parts can alter key genes that control cell division and immunity. ScienceDirectEpigenetic changes.
DNA methylation patterns place MGZL between cHL and PMBCL, shaping which genes turn on or off. NatureSex and age pattern.
More common in young to middle-aged adults; a slight male predominance is reported in series. (Exact rates vary across studies.) haematologica.orgBulky mediastinal mass.
While not a “cause,” the typical large chest mass reflects the tumor’s growth behavior and site of origin. haematologica.orgPrior thymic/mediastinal conditions (unclear).
No firm link, but research focuses on the unique thymic environment. (Biology-based inference, not a proven risk.) PMCFamily history of lymphoma (rare contributor).
Some lymphomas cluster in families, but a direct, strong link to MGZL is not proven. (General lymphoma risk context.) PMCImmune dysregulation (general).
States that weaken or twist immune control can aid lymphomagenesis in general, though specific MGZL data are limited. PMCEnvironmental exposures (uncertain).
No confirmed specific exposure causes MGZL; evidence is lacking. (Clarity based on reviews noting rarity and limited data.) haematologica.orgViral triggers (unlikely/unclear).
Unlike some lymphomas, clear links to EBV or other viruses are not typical for classic mediastinal GZL. PMCCheckpoint ligand alterations.
Amplification of PD-L1/PD-L2 region can promote immune escape and is shared with related entities. NatureTumor microenvironment resemblance to cHL.
Abundant inflammatory cells and special matrix can support tumor growth. PMCDiagnostic delay (not a cause, but a factor).
Because it mimics other diseases, diagnosis can be delayed, allowing growth. Expert review helps prevent this. nccn.orgOverlap biology with PMBCL/cHL creating a “gray zone.”
The core “risk” is the shared biology that makes the tumor behave like both. Recognizing the spectrum is key. Nature
Common symptoms and signs
Chest pressure or pain.
A growing mediastinal mass can press on the chest wall and cause pain or a heavy feeling. haematologica.orgShortness of breath.
The mass can press on the windpipe or lungs, making breathing hard with activity or even at rest. haematologica.orgDry cough.
Irritation or compression of airways can cause a persistent cough. haematologica.orgSwelling of face and neck (SVC syndrome).
Pressure on the superior vena cava can slow blood return, leading to swelling and visible veins. Seek urgent care if severe. haematologica.orgHoarseness.
Nerve pressure near the mediastinum can change the voice. haematologica.orgTrouble swallowing.
Esophageal compression can make food feel “stuck.” haematologica.orgUnexplained fever.
“B symptoms” (fever, night sweats, weight loss) can occur in aggressive lymphomas. PMCDrenching night sweats.
Soaking sweats at night are a classic lymphoma symptom. PMCUnplanned weight loss.
Losing >10% body weight over 6 months is a “B symptom” and signals active disease. PMCFatigue.
Cancer-related inflammation and energy use can cause marked tiredness. PMCPalpable lymph nodes (less common than chest mass).
Lymph nodes in the neck or armpit may enlarge, but the chest mass is more typical. haematologica.orgChest fullness when lying flat.
Pressure effects can worsen when reclining. haematologica.orgItching (pruritus).
Some lymphomas cause whole-body itching due to cytokines. PMCFrequent infections (occasionally).
Immune system disruption may raise infection risk in some people. PMCBack pain between the shoulder blades.
A large mass can cause referred pain to the back. haematologica.org
Diagnostic tests
A. Physical examination (what the doctor checks in the clinic)
General check and vital signs.
The doctor looks for fever, fast heart rate, low oxygen, or distress. They also review “B symptoms.” These basics guide urgent care and next tests. PMCNeck, armpit, and groin node exam.
The doctor gently feels for enlarged lymph nodes. Large nodes may suggest spread beyond the chest. PMCChest inspection for vein swelling.
Bulging chest or neck veins and facial puffiness can signal superior vena cava (SVC) obstruction. This needs quick attention. haematologica.orgBreathing exam (listening with a stethoscope).
Reduced airflow or unusual sounds can point to airway compression by a mass. haematologica.org
B. Manual/bedside tests (simple procedures done quickly)
Performance status scoring.
A brief walk-and-function check helps measure fitness for treatment. It also has prognostic value in aggressive lymphomas. PMCBedside oxygen saturation (pulse oximetry).
A finger sensor estimates blood oxygen. Low readings push doctors to act quickly on airway or SVC problems. haematologica.org
C. Laboratory and pathological tests (the core of diagnosis)
Complete blood count (CBC).
Looks for anemia, low or high white cells, and platelets. Results help assess overall health and guide safe treatment. PMCBlood chemistry (LDH, liver, kidney tests).
High LDH can signal fast-growing disease. Liver and kidney tests help plan safe dosing. PMCViral screens (HBV, HCV, HIV).
These are standard before immune-suppressing therapy in any lymphoma, to prevent reactivation and complications. PMCExcisional or core-needle biopsy of the mass or node (essential).
This is the most important test. A pathologist examines tissue under the microscope and orders special stains to prove the diagnosis. A tiny needle sample may be too small; doctors aim for enough tissue to run all tests. ASH PublicationsImmunohistochemistry (IHC) panel.
Stains look for B-cell markers (e.g., CD20, PAX5) and Hodgkin-type markers (e.g., CD30, CD15), plus others (e.g., CD23, MAL, PD-L1). The “mixed” pattern supports MGZL. PMCIn situ hybridization / molecular assays (selected).
Tests may assess EBV, PD-L1/PD-L2 amplification, or gene expression patterns that link MGZL to PMBCL/cHL biology. These help when routine stains are unclear. NatureExpert hematopathology review.
Because this entity sits between better-known cancers, an expert review avoids misclassification and guides proper therapy. nccn.org
D. Electrodiagnostic / heart–lung function tests (to assess safety and symptoms)
Electrocardiogram (ECG).
Checks heart rhythm and strain, especially if the mass is near the heart or if certain drugs are planned. PMCEchocardiogram (heart ultrasound).
Assesses heart function before some chemotherapies and checks for compression or fluid around the heart (pericardial effusion). PMCPulmonary function tests (PFTs).
Measure airway and lung capacity if the mass compresses the windpipe or if chest radiation is considered. PMC
E. Imaging tests (to find, size, and stage the disease)
Chest X-ray.
A simple first look that can show a widened mediastinum or large mass. It is quick and available almost everywhere. haematologica.orgCT scan of chest/neck/abdomen/pelvis.
Defines the size of the mass, checks nearby structures, and looks for disease in other areas. This is standard for staging. haematologica.orgPET-CT scan.
Shows active tumor areas using a sugar tracer (FDG). Helps with staging and response assessment in aggressive lymphomas. haematologica.orgMRI (selected cases).
Useful if the mass involves the spine, major vessels, or heart structures where soft-tissue detail matters. haematologica.org

rapid growth of a node, new hard mass, or sudden abdominal swelling.
Bleeding, black stools, severe bruising, or severe headache.
Can’t keep fluids down for 24 hours, or signs of dehydration.
Any sudden neurologic change (weakness, new seizures) after bispecifics or CAR-T. IDSA
What to eat and what to avoid
Eat: protein at each meal (eggs, fish, poultry, beans, tofu) to protect muscle.
Eat: colorful vegetables and fruits for fiber and micronutrients.
Eat: whole grains and healthy fats (olive oil, nuts) for steady energy.
Eat: safe dairy or pasteurized alternatives for calories and calcium if tolerated.
Drink: plenty of fluids; use oral rehydration if diarrhea.
Avoid: raw or undercooked meats/eggs/fish and unpasteurized products during neutropenia.
Avoid: high-dose supplements unless your clinician prescribes them (food-first is best). JNCCN
Limit: alcohol; it interacts with medicines and impairs healing.
Be careful with herbal products that affect bleeding or drug levels (turmeric/curcumin, St John’s wort, etc.). Frontiers
Ask early for a dietitian if weight is falling or taste is off. JNCCN
Frequently asked questions
Is a B-cell lymphocytic neoplasm the same as non-Hodgkin lymphoma?
Many are; “B-cell lymphocytic neoplasm” is a broad scientific term that includes most B-cell non-Hodgkin lymphomas and some leukemias like CLL/SLL. The exact name comes from pathology and genetics. Modern PathologyCan slow B-cell lymphoma be safely watched?
Yes—if there are no symptoms, normal organ function, and stable labs. You’ll have regular visits and scans. Treatment starts if the disease changes. Canadian Cancer SocietyWhat is the usual first treatment for fast types?
Often rituximab-based combination chemo like R-CHOP, sometimes with newer targeted drugs depending on subtype. NCBIWhat are targeted drugs?
Medicines that block survival signals (BTK inhibitors like ibrutinib/acalabrutinib/zanubrutinib) or trigger cell death (venetoclax) or direct immune attack (anti-CD20, bispecifics). FDA Access Data+3FDA Access Data+3FDA Access Data+3What is CAR-T?
Your own T-cells are engineered to attack CD19+ cancer cells, then given back in one infusion. Powerful and complex, with risks like CRS and neurotoxicity, delivered at certified centers. U.S. Food and Drug Administration+1Do I need a stem-cell transplant?
Only some patients do—often after relapse or for high-risk disease. Your team weighs benefits and risks carefully. NCBICan diet or supplements cure lymphoma?
No. Food supports strength and healing, but drugs/cell therapies treat the cancer. Use supplements only for deficiencies or specific side-effect management under medical advice. National Cancer InstituteWhy are vaccines important?
They reduce severe infections. Timing matters around therapy; most live vaccines are avoided. ASC PublicationsWhat is tumor lysis syndrome with venetoclax?
When many cancer cells die quickly, blood minerals shift. Doctors prevent this with a careful dose ramp-up, hydration, and labs. FDA Access DataWill treatment affect my heart?
Some chemo (doxorubicin) and targeted drugs can; teams check heart history and may monitor with scans/EKGs. NCBICan I work and exercise during treatment?
Often yes, at a safe level. Short, regular activity helps fatigue. Adjust by lab counts and symptoms. JNCCNHow are infections prevented during chemo?
Growth factors (G-CSF), careful hygiene, quick fever action, and sometimes antibiotic/antiviral/antifungal prophylaxis for highest-risk patients. IDSAAre bispecific antibodies the same as CAR-T?
No. Bispecifics are off-the-shelf antibodies that bring T-cells to cancer; CAR-T uses your engineered T-cells. Both can cause CRS but are delivered differently. FDA Access Data+1How do doctors choose a BTK inhibitor?
They consider side-effect profiles, heart history, drug interactions, and evidence by disease setting. FDA Access Data+1What is the outlook?
Outcomes vary widely by type and stage. Many indolent lymphomas are controllable for years; aggressive types are often curable with modern combinations and cellular therapies. NCBI+1
