ICD-10: C81.04

Nodular lymphocyte predominant Hodgkin lymphoma (NLPHL) is a distinct subtype of Hodgkin lymphoma characterized by the predominance of lymphocyte-rich nodules. The ICD-10 code C81.04 specifically refers to NLPHL located in the lymph nodes of the axilla and upper limb. Below is a detailed clinical description and relevant information regarding this condition.

Clinical Description of Nodular Lymphocyte Predominant Hodgkin Lymphoma (NLPHL)

Definition and Characteristics

Nodular lymphocyte predominant Hodgkin lymphoma is a rare form of Hodgkin lymphoma, accounting for approximately 5% of all Hodgkin lymphoma cases. It is characterized by the presence of large atypical cells known as popcorn cells or lymphocytic and histiocytic (L&H) cells, which are derived from B-lymphocytes. Unlike classical Hodgkin lymphoma, NLPHL typically has a more indolent course and a better prognosis.

Epidemiology

NLPHL predominantly affects younger adults, with a higher incidence in males than females. The median age at diagnosis is around 30 years, but it can occur at any age. The disease is often diagnosed at an early stage, which contributes to favorable outcomes.

Clinical Presentation

Patients with NLPHL may present with:
- Painless lymphadenopathy: The most common symptom, often involving the cervical, axillary, or inguinal lymph nodes.
- B symptoms: These include fever, night sweats, and unexplained weight loss, although they are less common in NLPHL compared to classical forms of Hodgkin lymphoma.
- Fatigue: Generalized fatigue may also be reported.

Diagnosis

Diagnosis of NLPHL involves:
- Histopathological examination: A biopsy of the affected lymph node is essential. The presence of popcorn cells and a background of reactive lymphocytes is indicative of NLPHL.
- Immunophenotyping: The atypical cells typically express CD20 and CD45, while being negative for CD15 and CD30, which helps differentiate NLPHL from classical Hodgkin lymphoma.
- Imaging studies: CT scans or PET scans may be used to assess the extent of the disease and to rule out other conditions.

Staging

The Ann Arbor staging system is commonly used for Hodgkin lymphoma, including NLPHL. Staging is crucial for determining treatment options and prognosis:
- Stage I: Involvement of a single lymph node region.
- Stage II: Involvement of two or more lymph node regions on the same side of the diaphragm.
- Stage III: Involvement of lymph node regions on both sides of the diaphragm.
- Stage IV: Disseminated involvement of one or more extralymphatic organs.

Treatment

The treatment for NLPHL may include:
- Watchful waiting: In cases where the disease is asymptomatic and localized.
- Chemotherapy: Common regimens include ABVD (Adriamycin, Bleomycin, Vinblastine, Dacarbazine) or other combinations, especially in advanced stages.
- Radiation therapy: Often used in localized disease or as a consolidation treatment after chemotherapy.
- Surgery: Rarely indicated, but may be performed for diagnostic purposes or in cases of localized disease.

Prognosis

The prognosis for NLPHL is generally favorable, with a high overall survival rate. The indolent nature of the disease often allows for effective management, and many patients achieve long-term remission.

Conclusion

ICD-10 code C81.04 designates nodular lymphocyte predominant Hodgkin lymphoma affecting the lymph nodes of the axilla and upper limb. Understanding the clinical characteristics, diagnostic criteria, and treatment options for NLPHL is essential for effective management and improved patient outcomes. Regular follow-up and monitoring are crucial to detect any potential recurrence or progression of the disease.
