ICD-10: C83.08

ICD-10 code C83.08 refers to Small cell B-cell lymphoma, specifically affecting the lymph nodes of multiple sites. This classification falls under the broader category of non-Hodgkin lymphoma (NHL), which encompasses a diverse group of blood cancers that originate in the lymphatic system.

Clinical Description

Definition

Small cell B-cell lymphoma is characterized by the proliferation of small, atypical B-lymphocytes. These lymphocytes are a type of white blood cell crucial for the immune response. The term "small cell" indicates the size of the malignant cells, which are typically smaller than those found in other types of lymphomas.

Pathophysiology

In small cell B-cell lymphoma, the malignant cells primarily infiltrate the lymph nodes, leading to lymphadenopathy (swelling of the lymph nodes). The disease can also involve other organs, but the lymph nodes are the most commonly affected sites. The exact cause of this lymphoma type is not fully understood, but it is believed to involve genetic mutations and environmental factors.

Symptoms

Patients with small cell B-cell lymphoma may present with a variety of symptoms, including:
- Lymphadenopathy: Swollen lymph nodes, often painless, in areas such as the neck, armpits, or groin.
- Fever: Unexplained fevers that may come and go.
- Night Sweats: Excessive sweating during the night.
- Weight Loss: Unintentional weight loss over a short period.
- Fatigue: Persistent tiredness that does not improve with rest.

Diagnosis

Diagnosis typically involves a combination of clinical evaluation, imaging studies (such as CT scans), and biopsy of affected lymph nodes. Histopathological examination reveals the characteristic small B-cells, and immunophenotyping may be used to confirm the B-cell lineage.

Staging

The staging of small cell B-cell lymphoma is crucial for determining the appropriate treatment approach. The Ann Arbor staging system is commonly used, which assesses the extent of lymph node involvement and whether the disease has spread to other organs.

Treatment Options

Chemotherapy

Chemotherapy is the primary treatment modality for small cell B-cell lymphoma. Regimens may include combinations of drugs such as cyclophosphamide, doxorubicin, vincristine, and prednisone (CHOP).

Radiation Therapy

Radiation therapy may be employed, particularly if the lymphoma is localized to specific lymph node regions or if there is a need to reduce tumor burden before chemotherapy.

Targeted Therapy

Recent advancements have introduced targeted therapies that focus on specific molecular pathways involved in the growth of B-cell lymphomas. These may include monoclonal antibodies and small molecule inhibitors.

Stem Cell Transplant

In certain cases, particularly for relapsed or refractory disease, autologous or allogeneic stem cell transplantation may be considered.

Prognosis

The prognosis for patients with small cell B-cell lymphoma varies based on several factors, including the stage at diagnosis, the patient's overall health, and response to treatment. Generally, early-stage disease has a better prognosis compared to advanced stages.

Conclusion

ICD-10 code C83.08 encapsulates a specific type of lymphoma that requires careful clinical assessment and management. Understanding the clinical features, diagnostic criteria, and treatment options is essential for healthcare providers to deliver effective care for patients diagnosed with small cell B-cell lymphoma affecting multiple lymph node sites.
