C84.18
Sézary disease, lymph nodes of multiple sites
Clinical Classification Guidelines
Medical Intelligence & Overview
Sézary disease is a rare and aggressive form of cutaneous T-cell lymphoma, a subtype of non-Hodgkin lymphoma that primarily affects the skin and blood. Characterized by the presence of malignant T-cells called Sézary cells in the bloodstream, this disease often involves multiple lymph node regions. The ICD-10 code C84.18 specifically indicates Sézary disease affecting lymph nodes at multiple sites, highlighting the widespread nature of the ailment.
Causes & Symptoms
Clinical Causes: Genetic mutations affecting T-cell function and regulation Potential environmental factors such as exposure to certain chemicals or radiation (though specific causes are not well-established) Immune system dysregulation leading to uncontrolled T-cell proliferation
Key Symptoms: Generalized redness and scaling of the skin, often resembling eczema or psoriasis Persistent itching and skin discomfort Presence of malignant T-cells in blood, known as Sézary cells Swollen lymph nodes in multiple regions of the body Skin thickening and infiltration Widespread hair loss in affected areas Fever, weight loss, and night sweats in advanced cases Fatigue and general malaise
Diagnostic & Treatment
Diagnosis Path: The diagnosis of Sézary disease involves multiple steps, including blood tests to identify Sézary cells, skin biopsies, and imaging studies to assess lymph node involvement. Specific laboratory tests include flow cytometry for cell analysis and molecular studies to detect genetic abnormalities associated with the disease. A comprehensive assessment helps distinguish Sézary disease from other skin lymphomas and skin conditions.
Treatment Protocols: Management of Sézary disease may include a combination of therapies aimed at controlling symptoms, reducing malignant cell counts, and improving quality of life. Treatment options encompass:
