Code Description

ICD-10 C82.66 is a billable code used to indicate a diagnosis of cutaneous follicle center lymphoma, intrapelvic lymph nodes.

Key Diagnostic Point:

Cutaneous follicle center lymphoma (CFCL) is a subtype of non-Hodgkin lymphoma that primarily affects the skin and is characterized by the proliferation of follicle center (germinal center) B-cells. When CFCL involves the intrapelvic lymph nodes, 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, which are indicative of systemic involvement. Diagnosis typically involves a combination of clinical examination, imaging studies, and biopsy of affected lymph nodes or skin lesions. Treatment protocols may include localized therapies such as radiation, systemic therapies like chemotherapy, or targeted therapies depending on the stage and severity of the disease. The prognosis varies based on the extent of lymph node involvement and the presence of B-symptoms, necessitating careful staging and monitoring.
