C90.30
Solitary plasmacytoma not having achieved remission
Clinical Classification Guidelines
Inclusion Terms
- Solitary plasmacytoma with failed remission
- Solitary plasmacytoma NOS
Medical Intelligence & Overview
Solitary plasmacytoma is a rare type of tumor consisting of abnormal plasma cells. When these abnormal cells form a single mass, it is called a solitary plasmacytoma. Sometimes, after treatment, the tumor does not respond as expected or the disease persists, leading to the classification of 'not having achieved remission.' The ICD-10 code C90.30 refers specifically to cases where a solitary plasmacytoma remains active or untreated, indicating that the disease has not entered remission or has relapsed.
Causes & Symptoms
Clinical Causes: Uncontrolled proliferation of abnormal plasma cells Genetic mutations affecting plasma cell growth Previous inadequate treatment or resistance to therapy Underlying plasma cell disorders progressing to localized tumors Environmental factors or exposures that may influence plasma cell behavior
Key Symptoms: Localized swelling or lump at the tumor site Pain or discomfort near the affected area Pathological fractures if the tumor weakens bones Few or no symptoms if the tumor is small or in early stages Possible neurological symptoms if the tumor impinges on nerves
Diagnostic & Treatment
Diagnosis Path: Medical history review and physical examination focusing on the tumor area Imaging studies such as X-rays, MRI, or CT scans to locate and assess the tumor Laboratory tests including blood tests to evaluate overall health and detect abnormal proteins Biopsy of the tumor tissue to examine plasma cells under a microscope Bone marrow biopsy to rule out multiple myeloma or other plasma cell disorders Serum and urine protein electrophoresis to identify abnormal monoclonal proteins
Treatment Protocols: Radiation therapy is the primary treatment aimed at eradicating the localized tumor Surgery may be considered if the tumor is accessible and resectable Chemotherapy is used in cases where the disease is not responding or has progressed Monitoring for disease progression or transformation into multiple myeloma Supportive care including pain management and fracture prevention
