C82.65
Cutaneous follicle center lymphoma, lymph nodes of inguinal region and lower limb
Clinical Classification Guidelines
Medical Intelligence & Overview
Cutaneous follicle center lymphoma (CFL) is a type of non-Hodgkin lymphoma that primarily affects the skin. Specifically, the code C82.65 indicates a form of this lymphoma involving the lymph nodes located in the inguinal region (area around the groin) and the lower limbs (legs). This condition originates from the abnormal growth of follicle center B-cells within the skin and adjacent lymph nodes, leading to skin lesions and possible involvement of nearby lymphatic tissue.
Causes & Symptoms
Clinical Causes: Genetic mutations in B-cells within the lymphatic system Chronic immune system stimulation Environmental factors, such as exposure to certain chemicals or radiation, though specific causes are not well understood Possible viral associations, although no definitive link has been established
Key Symptoms: Painless skin nodules or plaques, often appearing on the legs or groin area Progression to larger or more numerous skin lesions over time Swelling or enlargement of lymph nodes in the inguinal region Localized skin discoloration or changes in texture Rarely, systemic symptoms such as fever, night sweats, or weight loss may occur in advanced stages
Diagnostic & Treatment
Diagnosis Path: Physical examination focusing on skin lesions and lymph node swelling Skin biopsies to analyze tissue architecture and cellular characteristics Immunophenotyping tests to identify specific cell surface markers typical of follicle center B-cells Imaging studies such as CT or PET scans to assess the extent of lymph node and skin involvement Laboratory tests including blood counts and other relevant blood tests to evaluate overall health
Treatment Protocols: Localized radiation therapy can be effective for skin lesions Chemotherapy may be used for more widespread disease or aggressive cases Immunotherapy, targeting specific immune pathways, is sometimes considered Observation might be an option for indolent (slow-growing) forms without symptoms Regular follow-up is essential to monitor for disease progression or recurrence
