C90.12
Plasma cell leukemia in relapse
Clinical Classification Guidelines
Medical Intelligence & Overview
Plasma cell leukemia is a rare and aggressive form of blood cancer that originates from plasma cells in the bone marrow. When this disease returns after treatment, it is referred to as relapse. The medical classification for plasma cell leukemia in relapse is denoted by the ICD-10 code C90.12. This condition requires careful diagnosis and management due to its rapid progression and complex nature.
Causes & Symptoms
Clinical Causes: Uncontrolled proliferation of abnormal plasma cells that escape normal immune regulation Genetic mutations within plasma cells that lead to malignant transformation Previous treatments failing to eradicate malignant cells, leading to recurrence Potential environmental and genetic factors influencing the development and relapse
Key Symptoms: Bone pain, especially in the ribs, skull, or long bones Fatigue and weakness due to anemia Easy bruising or bleeding resulting from low platelet counts Frequent infections owing to immune system impairment Unexplained weight loss and fever Enlarged spleen or liver in some cases
Diagnostic & Treatment
Diagnosis Path: Blood tests revealing a high number of plasma cells circulating in the bloodstream Bone marrow biopsy showing a significant proliferation of abnormal plasma cells (usually more than 20% of marrow cells) Immunophenotyping to identify abnormal plasma cell markers Serum protein electrophoresis and immunofixation to detect abnormal monoclonal proteins Imaging scans like X-rays, MRI, or PET scans to detect bone damage or organ involvement
Treatment Protocols: Chemotherapy regimens designed to target rapidly dividing plasma cells Use of targeted therapies that focus on specific molecules or pathways involved in the disease Immunotherapy strategies to boost the immune system's ability to fight cancer High-dose chemotherapy followed by stem cell transplantation for eligible patients Supportive care such as blood transfusions, antibiotics, and medications to manage symptoms and prevent complications
