Code Description

ICD-10 C82.65 is a billable code used to indicate a diagnosis of cutaneous follicle center lymphoma, lymph nodes of inguinal region and lower limb.

Key Diagnostic Point:

Cutaneous follicle center lymphoma (CFCL) is a type of non-Hodgkin lymphoma that primarily affects the skin and can involve lymph nodes. It is characterized by the proliferation of follicle center (germinal center) B-cells. When CFCL involves the lymph nodes of the inguinal region and lower limb, it indicates a more advanced stage of the disease, often associated with systemic symptoms. Patients may present with localized skin lesions, which can be mistaken for other dermatological conditions. The disease can manifest with B-symptoms such as fever, night sweats, and weight loss, indicating a more aggressive form of lymphoma. Diagnosis typically involves a combination of clinical evaluation, imaging studies, and biopsy of affected lymph nodes or skin lesions. Treatment options may include localized radiation therapy, chemotherapy, or immunotherapy, depending on the stage and severity of the disease. Regular follow-up is essential to monitor for disease progression or recurrence.
