C82.91
Follicular lymphoma, unspecified, lymph nodes of head, face, and neck
Clinical Classification Guidelines
Medical Intelligence & Overview
Follicular lymphoma is a type of non-Hodgkin lymphoma that primarily affects the lymphatic system, which is part of the immune system. Specifically, when classified under ICD-10 code C82.91, it indicates a case where the lymphoma involves the lymph nodes located in the head, face, and neck area. This form of lymphoma develops from B lymphocytes, which are cells responsible for producing antibodies. Although it can occur at any age, follicular lymphoma is more commonly diagnosed in middle-aged and older adults. The course of the disease can vary widely, with some cases progressing slowly over many years, while others may advance more rapidly.
Causes & Symptoms
Clinical Causes: Genetic mutations affecting B lymphocytes Chronic immune system stimulation Increased age, as it's more common in older adults Possible links with certain infections or exposures (though not definitively established)
Key Symptoms: Painless swelling in the lymph nodes of the head, face, or neck B symptoms such as fever, night sweats, and weight loss (less common in early stages) Fatigue or weakness Enlargement of lymph nodes that persists over time In some cases, symptoms related to compression of nearby structures, like discomfort or difficulty swallowing
Diagnostic & Treatment
Diagnosis Path: Lymph node biopsy, examining tissue under a microscope for characteristic cell features Immunophenotyping to identify specific markers on the abnormal B cells Imaging studies such as CT or PET scans to determine the extent of disease spread Blood tests to assess overall health and detect involvement of other organs
Treatment Protocols: Watchful waiting in cases where the lymphoma is slow-growing and asymptomatic Radiation therapy targeted at affected lymph nodes Chemotherapy to kill cancerous cells Immunotherapy to boost the immune system's ability to fight the disease Targeted therapies that focus on specific molecules involved in lymphoma growth
