ICD-10: C82.89

Follicular lymphoma, classified under ICD-10 code C82.89, refers to a subtype of non-Hodgkin lymphoma that primarily affects the lymphatic system but can also manifest in extranodal and solid organ sites. The diagnosis of this condition involves a combination of clinical evaluation, imaging studies, laboratory tests, and histopathological examination. Below is a detailed overview of the criteria used for diagnosing this specific type of follicular lymphoma.

Clinical Presentation

Symptoms

Patients with follicular lymphoma may present with a variety of symptoms, including:
- Lymphadenopathy: Swelling of lymph nodes, which may be painless.
- B Symptoms: These include fever, night sweats, and unexplained weight loss, which can indicate more aggressive disease.
- Extranodal Involvement: Symptoms may vary depending on the organ affected, such as abdominal pain if the gastrointestinal tract is involved.

Medical History

A thorough medical history is essential, including:
- Previous history of lymphoma or other hematological malignancies.
- Family history of lymphomas or related conditions.
- Exposure to risk factors such as certain infections (e.g., HIV, Hepatitis C) or environmental toxins.

Diagnostic Tests

Imaging Studies

Imaging plays a crucial role in identifying the extent of the disease:
- CT Scans: Used to assess lymph node involvement and detect extranodal sites.
- PET Scans: Helpful in evaluating metabolic activity of lymphomas and distinguishing between active disease and residual masses post-treatment.

Laboratory Tests

• Complete Blood Count (CBC): To check for anemia, thrombocytopenia, or leukopenia, which may indicate bone marrow involvement.
• Lactate Dehydrogenase (LDH): Elevated levels can suggest a more aggressive disease.

Histopathological Examination

Biopsy

A definitive diagnosis of follicular lymphoma requires a biopsy of the affected tissue:
- Excisional Biopsy: Preferred method for obtaining a representative sample of lymph nodes.
- Core Needle Biopsy: May be used for solid organ involvement.

Immunophenotyping

• Flow Cytometry: This technique is used to analyze the surface markers on the lymphoma cells. Follicular lymphoma typically expresses CD19, CD20, and CD10, along with B-cell markers.
• Cytogenetic Analysis: Detection of the t(14;18) translocation is characteristic of follicular lymphoma, leading to the overexpression of the BCL2 gene.

Histological Classification

The World Health Organization (WHO) classification is used to categorize follicular lymphoma based on histological features:
- Grade 1-2: Indolent forms with a predominance of small cleaved cells.
- Grade 3: More aggressive forms, which may require different treatment approaches.

Extranodal and Solid Organ Involvement

For cases classified under C82.89, the diagnosis may also involve:
- Assessment of Extranodal Sites: This includes evaluating organs such as the spleen, liver, or gastrointestinal tract through imaging and biopsy.
- Differential Diagnosis: It is crucial to differentiate follicular lymphoma from other lymphomas and malignancies that may present similarly in solid organs.

Conclusion

The diagnosis of follicular lymphoma, particularly the subtype represented by ICD-10 code C82.89, is a multifaceted process that combines clinical evaluation, imaging, laboratory tests, and histopathological analysis. Accurate diagnosis is essential for determining the appropriate treatment strategy and prognosis. If you suspect you or someone else may have this condition, it is important to consult a healthcare professional for a comprehensive evaluation and diagnosis.

ICD-10 code C82.89 refers to "Other types of follicular lymphoma, extranodal and solid organ sites." Follicular lymphoma is a subtype of non-Hodgkin lymphoma (NHL) characterized by the proliferation of follicle center (germinal center) B-cells. This specific code encompasses cases of follicular lymphoma that occur outside of the typical nodal sites, affecting various extranodal locations and solid organs.

Clinical Presentation

General Characteristics

Follicular lymphoma typically presents as a slow-growing, indolent form of lymphoma. Patients may be asymptomatic for extended periods, with the disease often discovered incidentally during imaging studies or routine examinations.

2. Extranodal Involvement: Symptoms may arise from the specific organ affected, such as:
   - Gastrointestinal Tract: Abdominal pain, nausea, vomiting, or changes in bowel habits.
   - Bone Marrow: Symptoms of anemia (fatigue, pallor), thrombocytopenia (easy bruising, bleeding), or leukopenia (increased infections).
   - Skin: Cutaneous lesions or rashes may occur if the lymphoma infiltrates the skin.
   - Central Nervous System: Neurological symptoms such as headaches, seizures, or cognitive changes if the lymphoma involves the brain or spinal cord.

3. B Symptoms: These include fever, night sweats, and unexplained weight loss, which can indicate more aggressive disease or transformation to a higher-grade lymphoma.

Patient Characteristics

Demographics

• Age: Follicular lymphoma primarily affects adults, with a median age of diagnosis around 60 years. However, it can occur in younger individuals.
• Gender: There is a slight male predominance in follicular lymphoma cases.

Risk Factors

• Family History: A family history of lymphoma or other hematologic malignancies may increase risk.
• Immunosuppression: Patients with compromised immune systems, such as those with HIV/AIDS or those on immunosuppressive therapy, are at higher risk.
• Environmental Exposures: Certain environmental factors, including exposure to pesticides and solvents, have been associated with an increased risk of developing non-Hodgkin lymphoma.

Comorbidities

Patients may present with various comorbid conditions, which can complicate the clinical picture. Common comorbidities include cardiovascular disease, diabetes, and other malignancies, which may influence treatment decisions and overall prognosis.

Conclusion

Follicular lymphoma, particularly the subtype classified under ICD-10 code C82.89, refers to other types of follicular lymphoma that occur in extranodal and solid organ sites. This condition is a type of non-Hodgkin lymphoma (NHL) characterized by the proliferation of follicle center (germinal center) B-cells. The treatment approaches for this subtype can vary based on several factors, including the stage of the disease, the patient's overall health, and specific characteristics of the lymphoma. Below, we explore the standard treatment modalities for this condition.

Standard Treatment Approaches

1. Chemotherapy

Chemotherapy remains a cornerstone of treatment for follicular lymphoma, especially in cases where the disease is symptomatic or aggressive. Common regimens include:

• CHOP Regimen: This includes Cyclophosphamide, Doxorubicin, Vincristine, and Prednisone. It is often used for more aggressive forms of lymphoma.
• R-CHOP: The addition of Rituximab (a monoclonal antibody) to the CHOP regimen has significantly improved outcomes for patients with follicular lymphoma. Rituximab targets CD20 on B-cells, enhancing the effectiveness of chemotherapy.

2. Immunotherapy

Immunotherapy has become increasingly important in the treatment of follicular lymphoma. Key options include:

• Rituximab: As mentioned, this monoclonal antibody is frequently used in combination with chemotherapy. It can also be used as a single agent in patients with relapsed or refractory disease.
• Obinutuzumab: Another anti-CD20 monoclonal antibody that may be used in combination with chemotherapy or as maintenance therapy.

3. Targeted Therapy

Targeted therapies are designed to attack specific pathways involved in cancer cell growth. For follicular lymphoma, these include:

• PI3K Inhibitors: Drugs like Copanlisib (Aliqopa®) are used for patients who have relapsed after at least two prior therapies. These agents target the PI3K pathway, which is often activated in lymphoma cells.
• BTK Inhibitors: Ibrutinib is another option that has shown efficacy in treating various types of B-cell malignancies, including follicular lymphoma.

4. Radiation Therapy

Radiation therapy may be employed in specific scenarios, particularly for localized disease or as a palliative measure to relieve symptoms. Techniques such as Intensity Modulated Radiation Therapy (IMRT) can be used to minimize damage to surrounding healthy tissues while effectively targeting the lymphoma.

5. Stem Cell Transplantation

For patients with relapsed or refractory follicular lymphoma, especially those who have undergone multiple lines of therapy, autologous stem cell transplantation may be considered. This approach involves harvesting the patient's stem cells, administering high-dose chemotherapy, and then reinfusing the stem cells to restore bone marrow function.

6. Clinical Trials

Participation in clinical trials can provide access to new and emerging therapies that may not yet be widely available. These trials often explore novel agents or combinations of existing treatments and can be a valuable option for patients with difficult-to-treat forms of follicular lymphoma.

Conclusion

The treatment of follicular lymphoma classified under ICD-10 code C82.89 involves a multifaceted approach that includes chemotherapy, immunotherapy, targeted therapy, radiation, and potentially stem cell transplantation. The choice of treatment is highly individualized, taking into account the specific characteristics of the lymphoma and the patient's overall health. As research continues to evolve, new therapies and combinations are likely to emerge, offering hope for improved outcomes in patients with this challenging condition. For those considering treatment options, consulting with a hematologist or oncologist specializing in lymphoma is crucial for developing a tailored treatment plan.

ICD-10 code C82.89 refers to "Other types of follicular lymphoma, extranodal and solid organ sites." This classification falls under the broader category of non-Hodgkin lymphoma (NHL), specifically focusing on follicular lymphoma, which is a type of B-cell lymphoma characterized by the proliferation of follicle center (germinal center) B-cells.

Clinical Description of Follicular Lymphoma

Overview

Follicular lymphoma is a slow-growing (indolent) form of non-Hodgkin lymphoma that typically arises from the lymphatic system. It is characterized by the presence of neoplastic follicle center cells, which can lead to the formation of lymphoid follicles. While follicular lymphoma primarily affects lymph nodes, it can also manifest in extranodal sites, which include various solid organs such as the spleen, liver, and bone marrow.

Extranodal Involvement

The designation "extranodal" indicates that the lymphoma is not confined to lymph nodes but has spread to other organs. This can complicate diagnosis and treatment, as the symptoms may vary significantly depending on the affected organ. Common sites of extranodal involvement in follicular lymphoma include:

• Bone marrow: Involvement can lead to cytopenias due to marrow infiltration.
• Spleen: Splenomegaly is often observed, which may cause discomfort or fullness.
• Liver: Hepatomegaly can occur, potentially leading to liver dysfunction.
• Gastrointestinal tract: This can result in symptoms such as abdominal pain, obstruction, or gastrointestinal bleeding.

Symptoms

Patients with C82.89 may present with a variety of symptoms, including:

• Painless lymphadenopathy (swollen lymph nodes)
• Fatigue
• Unexplained weight loss
• Night sweats
• Fever
• Abdominal discomfort or fullness due to organ enlargement

Diagnosis

Diagnosis typically involves a combination of clinical evaluation, imaging studies (such as CT scans or PET scans), and histopathological examination of biopsy samples. Immunophenotyping and genetic studies may also be performed to confirm the diagnosis and assess the specific subtype of follicular lymphoma.

Treatment

Treatment for follicular lymphoma, particularly when it involves extranodal sites, may vary based on the extent of the disease, the patient's overall health, and specific symptoms. Common treatment modalities include:

• Watchful waiting: In cases where the disease is asymptomatic and indolent.
• Chemotherapy: Often combined with immunotherapy (e.g., rituximab).
• Radiation therapy: Particularly for localized disease.
• Targeted therapies: Such as BTK inhibitors or PI3K inhibitors, which may be used in relapsed or refractory cases.

Conclusion

ICD-10 code C82.89 captures the complexity of follicular lymphoma when it presents in extranodal and solid organ sites. Understanding the clinical features, diagnostic approaches, and treatment options is crucial for effective management of this condition. As with all lymphomas, early detection and tailored treatment strategies are essential for improving patient outcomes.
