Code Description

ICD-10 C82.55 is a billable code used to indicate a diagnosis of diffuse follicle center lymphoma, lymph nodes of inguinal region and lower limb.

Key Diagnostic Point:

Diffuse follicle center lymphoma (DFCL) is a subtype of non-Hodgkin lymphoma characterized by the proliferation of neoplastic B-cells within the follicle center of lymphoid tissue. This specific code pertains to cases where the lymphoma is localized to the lymph nodes of the inguinal region and lower limb. Clinically, patients may present with painless lymphadenopathy, often accompanied by systemic B-symptoms such as fever, night sweats, and unexplained weight loss. The diagnosis is typically confirmed through histopathological examination of lymph node biopsies, which reveal a diffuse pattern of follicle center cell proliferation. Staging of the disease is crucial for determining prognosis and treatment, with the Ann Arbor staging system commonly employed. Treatment protocols may include chemotherapy, immunotherapy, and in some cases, radiation therapy, depending on the stage and overall health of the patient. Regular follow-up is essential to monitor for disease progression or recurrence.
