C85.91

Clinical Causes: Genetic mutations that cause abnormal lymphocyte growth Immune system deficiencies or suppression Exposure to certain chemicals or pesticides Infections with viruses such as Epstein-Barr virus (EBV) or Human T-cell lymphotropic virus (HTLV) Age-related changes, with higher incidence in older adults History of radiation therapy or chemotherapy

Key Symptoms: Swelling or painless lumps in the face, neck, or jaw Persistent sore throat or cough Unexplained weight loss Fever and night sweats Fatigue or weakness Difficulty swallowing or breathing in severe cases Persistent pain or discomfort in affected areas

Diagnosis Path: Diagnosing this form of NHL involves multiple steps, including physical examinations to detect swollen lymph nodes, and a combination of imaging tests such as CT scans, PET scans, and ultrasounds to assess the extent of the disease. A definitive diagnosis is made through a biopsy, where a small tissue sample from a swollen lymph node is examined under a microscope. Blood tests may also be performed to evaluate overall health and organ function. Additional tests may include bone marrow biopsies or molecular studies to identify specific lymphoma subtypes and guide treatment options.

Treatment Protocols: Treatment approaches for non-Hodgkin lymphoma of the head, face, and neck typically involve systemic therapies, which can include chemotherapy, targeted therapy, immunotherapy, or a combination thereof. Radiation therapy may be used to target specific lymph nodes or affected tissues. In some cases, especially for early-stage disease, watchful waiting might be an option until symptoms progress. The choice of treatment depends on various factors such as the precise type and stage of lymphoma, patient health, and response to initial therapy. Participation in clinical trials may also be considered to access new or experimental treatments. Supportive care, including managing side effects and maintaining quality of life, plays a vital role in comprehensive care.
