ICD-10: C82.29

ICD-10 code C82.29 refers to Follicular lymphoma grade III, unspecified, extranodal and solid organ sites. This classification is part of the broader category of non-Hodgkin lymphomas, specifically follicular lymphomas, which are characterized by their origin in the lymphatic system and their tendency to form in lymph nodes and other tissues.

Clinical Description of Follicular Lymphoma

Overview

Follicular lymphoma is a type of indolent (slow-growing) non-Hodgkin lymphoma that arises from B-lymphocytes, specifically from the germinal center of lymphoid follicles. It is classified into different grades based on histological features, with grade III being more aggressive than grades I and II. Grade III follicular lymphoma is further divided into two subtypes: grade IIIA (which retains some follicular architecture) and grade IIIB (which is more diffuse and lacks follicular structures).

Characteristics

• Histological Features: Grade III follicular lymphoma is characterized by a higher proliferation index, often indicated by a higher number of mitotic figures and a more diffuse pattern of growth compared to lower-grade follicular lymphomas. The presence of large cells (centroblasts) is a hallmark of this grade.
• Clinical Presentation: Patients may present with lymphadenopathy (swollen lymph nodes), splenomegaly (enlarged spleen), or extranodal involvement, which can affect various organs such as the gastrointestinal tract, skin, or bone marrow. Symptoms may include fatigue, weight loss, fever, and night sweats, although some patients may be asymptomatic at diagnosis.

Extranodal and Solid Organ Involvement

The designation of "extranodal and solid organ sites" indicates that the lymphoma has spread beyond the lymphatic system to other organs. Common sites of extranodal involvement in follicular lymphoma include:

• Gastrointestinal Tract: The stomach and intestines are frequent sites for extranodal involvement, leading to symptoms such as abdominal pain, nausea, or gastrointestinal bleeding.
• Bone Marrow: Involvement of the bone marrow can lead to cytopenias (low blood cell counts) and may affect the overall prognosis.
• Skin: Cutaneous manifestations can occur, presenting as nodules or plaques.
• Other Organs: Follicular lymphoma can also affect the lungs, liver, and central nervous system, although these are less common.

Diagnosis and Staging

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 prognostic factors.

Staging of follicular lymphoma is crucial for determining the appropriate treatment approach. The Ann Arbor staging system is commonly used, which considers the number of affected lymph node regions and the presence of extranodal disease.

Treatment Options

Treatment for follicular lymphoma, particularly grade III, may include:

• Chemotherapy: Regimens such as R-CHOP (rituximab, cyclophosphamide, doxorubicin, vincristine, and prednisone) are commonly used.
• Targeted Therapy: Agents like rituximab, a monoclonal antibody targeting CD20 on B-cells, are often included in treatment plans.
• Radiation Therapy: May be used for localized disease or as part of a combined modality approach.
• Stem Cell Transplantation: In selected cases, particularly for relapsed or refractory disease, autologous stem cell transplantation may be considered.

Prognosis

The prognosis for patients with follicular lymphoma can vary significantly based on several factors, including the grade of the lymphoma, the extent of disease at diagnosis, and the patient's overall health. Grade III follicular lymphoma generally has a more aggressive course compared to lower grades, and treatment strategies are often more intensive.

In summary, ICD-10 code C82.29 captures the complexity of follicular lymphoma grade III with extranodal involvement, highlighting the need for comprehensive clinical evaluation and tailored treatment strategies to manage this condition effectively.

Follicular lymphoma, particularly grade III, is a subtype of non-Hodgkin lymphoma characterized by its indolent nature and specific clinical presentations. The ICD-10 code C82.29 refers to "Follicular lymphoma grade III, unspecified, extranodal and solid organ sites." Understanding the clinical presentation, signs, symptoms, and patient characteristics associated with this condition is crucial for diagnosis and management.

Clinical Presentation

Overview of Follicular Lymphoma

Follicular lymphoma is a type of B-cell lymphoma that typically arises from follicle center (germinal center) B-cells. It is classified into different grades based on histological features, with grade III indicating a more aggressive form. This subtype can present in various extranodal sites, including the skin, gastrointestinal tract, and other solid organs.

Signs and Symptoms

Patients with follicular lymphoma grade III may exhibit a range of signs and symptoms, which can vary based on the extent of the disease and the specific organs involved:

• Lymphadenopathy: Swelling of lymph nodes is common, particularly in the cervical, axillary, or inguinal regions. Patients may notice painless lumps under the skin.
• B Symptoms: These include fever, night sweats, and unexplained weight loss. The presence of B symptoms often indicates a more advanced disease stage.
• Fatigue: Patients frequently report significant fatigue, which can be debilitating and affect daily activities.
• Abdominal Symptoms: If the lymphoma involves the gastrointestinal tract, patients may experience abdominal pain, nausea, vomiting, or changes in bowel habits.
• Skin Manifestations: Extranodal involvement can lead to skin lesions, which may appear as plaques or nodules.
• Organ-Specific Symptoms: Depending on the solid organ affected (e.g., liver, spleen), patients may present with organ-specific symptoms such as jaundice (if the liver is involved) or splenomegaly (enlarged spleen).

Patient Characteristics

Certain demographic and clinical characteristics are often associated with patients diagnosed with follicular lymphoma grade III:

• Age: Follicular lymphoma typically occurs in 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 the incidence of follicular lymphoma.
• Comorbidities: Patients may have other health conditions, such as autoimmune diseases or previous malignancies, which can complicate the clinical picture.
• Family History: A family history of lymphoproliferative disorders may be noted in some patients, suggesting a potential genetic predisposition.

Diagnostic Considerations

Diagnosis of follicular lymphoma grade III involves a combination of clinical evaluation, imaging studies, and histopathological examination. Key diagnostic tools include:

• Biopsy: A tissue biopsy is essential for confirming the diagnosis and determining the grade of lymphoma.
• Imaging Studies: CT scans, PET scans, or MRI may be utilized to assess the extent of disease and identify extranodal involvement.
• Laboratory Tests: Blood tests may reveal anemia, elevated lactate dehydrogenase (LDH), or other abnormalities indicative of lymphoma.

Conclusion

Follicular lymphoma grade III, particularly when it presents in extranodal and solid organ sites, poses unique challenges in clinical management. Recognizing the signs and symptoms, understanding patient characteristics, and employing appropriate diagnostic strategies are essential for effective treatment planning. Given the indolent nature of follicular lymphoma, early detection and intervention can significantly impact patient outcomes and quality of life.
