These tests can show whether you have lymphoma cells or abnormal levels of normal cells:
Blood smear: We take a drop of blood and look at it under a microscope. Complete blood count (CBC): A complete blood count (CBC) measures red blood cells, white blood cells and platelets..
How do you scan for lymphoma?
Computed tomography (CT) scan A CT scan combines many x-rays to make detailed, cross-sectional images of your body. This scan can help tell if any lymph nodes or organs in your body are enlarged. CT scans are useful for looking for lymphoma in the abdomen, pelvis, chest, head, and neck..
What are the cell markers for lymphoma?
CD2 is a pan T-cell lineage marker which is positive in most of the lymphomas of T-cell lineage. CD5 is expressed in most small lymphocytic lymphoma, mantle cell lymphoma and few cases of follicular center cell lymphoma. CD5 is negative in Burkitt lymphoma, marginal zone lymphoma and multiple myeloma..
What cells are in the cytology of lymph nodes?
Cytologically, reactive nodes will contain increased numbers of plasma cells, possibly with some inflammatory cells, along with the resident lymphoid population. If inflammation is present, neutrophils and macrophages also will be found and the type of inflammation may be classified..
What is lymph node cytology?
Lymph node cytology is an excellent way to evaluate a lymphadenopathy whether it is a single node enlarged, multiple nodes enlarged, or a generalized lymphadenopathy. If multiple lymph nodes are enlarged, more than one should be sampled..
What is lymphoma histology?
Histologically, the lymphoma cells usually demonstrate immunoblastic or plasmablastic morphology, with expression of plasma cell markers (CD138 and/or CD38) and frequent loss of B-cell markers (CD20 and CD79a). Nearly all cases of PBL are EBV-positive, and they are negative for HHV8 (Figure .

Lymph Node Biopsy A specialist removes part or all of a lymph node for testing. Many lymph nodes are close to the skin's surface, so the procedure is usually simple. Pathologists who specialize in blood cancers analyze the tissue under a microscope. The results will determine whether you have lymphoma and what type.
Fine needle aspiration (FNA) cytology is a simple and useful tool to screen malignant lymphoma involving the lymph node; however, it may give rise to false negative or false positive re- sults particularly in low grade lymphoma.
Lymphoma. The most common finding on fine-needle aspiration and cytology of lymph nodes that are enlarged due to lymphoma is a monomorphic population of lymphoblasts (Figure 2). Characteristics of lymphoma identified by lymph node cytology are listed in Table 3.
How is chronic lymphoma (CLL) diagnosed?
In general, patients with CLL present with a wide range of symptoms and multiple enlarged lymph nodes and the diagnosis is frequently made through peripheral blood analysis. Therefore, it is rather unusual that a first diagnosis of CLL be carried out in an FNB of an isolated lymph node.

What is the cytomorphology of lymphoma?
H&E. ×400. Some lymphomas, mainly FL and MZL, can also share a polymorphous and heterogeneous cytomorphology that simulates a reactive pattern (fig. 5 a). In contrast, a monotonous and monomorphous lymphocytic population is highly suspicious for malignancy.

Where were cytopathology reports performed for clinically suspected lymphoma?
The electronic medical records of the Department of Pathology at Massachusetts General Hospital (Boston, Massachusetts) were retrospectively searched for cytopathology reports where FNA of a lymph node was performed for clinically suspected lymphoma during 2018 and 2019.
Cytology lymphoma
Medical condition
Indolent lymphoma, also known as low-grade lymphoma, is a group of slow-growing non-Hodgkin lymphomas (NHLs). Because they spread slowly, they tend to have fewer signs and symptoms when first diagnosed and may not require immediate treatment. Symptoms can include swollen but painless lymph nodes, unexplained fever, and unintended weight loss.
Intraocular lymphoma is a rare malignant form of eye cancer. Intraocular lymphoma may affect the eye secondarily from a metastasis from a non-ocular tumor or may arise within the eye primarily. PIOL is a subset of primary central nervous system lymphoma (PCNSL). PCNSL are most commonly a diffuse large B-cell immunohistologic subtype of non-Hodgkin's lymphoma according to the World Health Organization (WHO) classification of lymphomas. The most common symptoms of PIOL include blurred or decreased vision due to tumor cells in the vitreous. Most cases of PIOL eventuate to central nervous system involvement (PCNSL) while only 20% of PCNSL lead to intraocular (PIOL) involvement. PIOL and PCNSL remain enigmas because both structures are immunologically privileged sites and so do not normally have immune cells trafficking through these structures. What is more, while the vast majority of PCNSL in patients with acquired immune deficiency syndrome (AIDS) is related to the Epstein-Barr virus (EBV), the development of PCNSL and PIOL in immunocompetent patients is unknown and shows no general relation to infectious DNAs.
Mantle cell lymphoma (MCL) is a type of
Type of blood cancer
Mantle cell lymphoma (MCL) is a type of non-Hodgkin's lymphoma, comprising about 6% of cases. It is named for the mantle zone of the lymph nodes where it develops. The term 'mantle cell lymphoma' was first adopted by Raffeld and Jaffe in 1991.
Medical condition
Mixed-cell lymphomas are lymphomas that have both large cells and small cells in them. This nomenclature is derived from an older system of pathology, before technological advances allowed much more precise descriptions of the affected cancerous cells.
Peripheral T-cell lymphoma not otherwise specified (PTCL-NOS)
Medical condition
Peripheral T-cell lymphoma not otherwise specified (PTCL-NOS), is a subtype of peripheral T-cell lymphoma. Peripheral T-cell lymphoma (PTCL) is defined as a diverse group of aggressive lymphomas that develop from mature-stage white blood cells called T-cells and natural killer cells. PTCL is a type of non-Hodgkin's lymphoma (NHL). PTCL specifically affects T-cells rather than B-cells, and results when T-cells develop and grow abnormally.
Primary central nervous system lymphoma (PCNSL)
Medical condition
Primary central nervous system lymphoma (PCNSL), also termed primary diffuse large B-cell lymphoma of the central nervous system (DLBCL-CNS), is a primary intracranial tumor appearing mostly in patients with severe immunodeficiency. It is a subtype and one of the most aggressive of the diffuse large B-cell lymphomas.
Primary effusion lymphoma (PEL) is classified as a diffuse large
Medical condition
Primary effusion lymphoma (PEL) is classified as a diffuse large B cell lymphoma. It is a rare malignancy of plasmablastic cells that occurs in individuals that are infected with the Kaposi's sarcoma-associated herpesvirus. Plasmablasts are immature plasma cells, i.e. lymphocytes of the B-cell type that have differentiated into plasmablasts but because of their malignant nature do not differentiate into mature plasma cells but rather proliferate excessively and thereby cause life-threatening disease. In PEL, the proliferating plasmablastoid cells commonly accumulate within body cavities to produce effusions, primarily in the pleural, pericardial, or peritoneal cavities, without forming a contiguous tumor mass. In rare cases of these cavitary forms of PEL, the effusions develop in joints, the epidural space surrounding the brain and spinal cord, and underneath the capsule which forms around breast implants. Less frequently, individuals present with extracavitary primary effusion lymphomas, i.e., solid tumor masses not accompanied by effusions. The extracavitary tumors may develop in lymph nodes, bone, bone marrow, the gastrointestinal tract, skin, spleen, liver, lungs, central nervous system, testes, paranasal sinuses, muscle, and, rarely, inside the vasculature and sinuses of lymph nodes. As their disease progresses, however, individuals with the classical effusion-form of PEL may develop extracavitary tumors and individuals with extracavitary PEL may develop cavitary effusions.
