C83.93

Clinical Causes: Genetic mutations within lymphocytes leading to abnormal growth Chronic immune stimulation or inflammation Certain infections, such as viruses that impact immune cells Environmental exposures, including chemicals and radiation Aging, which can influence immune system function

Key Symptoms: Swelling or painless enlargement of lymph nodes in the abdomen Abdominal discomfort or pain Unintended weight loss Fever or night sweats Fatigue or weakness Feeling of fullness or bloating in the abdomen Loss of appetite Possible gastrointestinal symptoms like nausea or changes in bowel habits

Diagnosis Path: Diagnosing intra-abdominal non-follicular lymphoma involves several steps. Initially, a healthcare provider reviews medical history and performs a physical exam, focusing on the abdomen for enlarged lymph nodes or masses. Imaging studies such as ultrasound, CT scans, or PET scans help visualize the lymph nodes and detect abnormal masses. Confirmatory diagnosis requires a biopsy, where tissue from the affected lymph node is examined microscopically. Additional tests, including blood work and molecular studies, can help determine the subtype and extent of the disease, guiding appropriate treatment planning.

Treatment Protocols: Management of non-follicular (diffuse) lymphoma typically involves oncology specialists. Treatment options may include chemotherapy to target cancer cells, immunotherapy to boost the immune response, targeted therapy aimed at specific molecular features of the cancer, or radiation therapy in some cases. The choice of treatment depends on the stage, location, and overall health of the patient. Regular monitoring and follow-up assessments are essential to evaluate response and detect any recurrence. Supportive care to manage symptoms and maintain quality of life is also an important aspect of treatment planning.
