POEMS syndrome characterized by bone lesions: A case report.

ABSTRACT

RATIONALE POEMS (polyneuropathy, organomegaly, endocrinopathy, monoclonal paraproteinemia, and skin changes) syndrome is a rare clinical syndrome characterized by multiple peripheral neuropathies, hepatosplenomegaly, endocrine disorders, monoclonal paraproteinemia, and dermatosis. The main manifestations of POMES were nerve and skin changes, and bone disease was not reported. Here, we report a case of POEMS syndrome with the main manifestation of bone lesions. PATIENT CONCERNS POMES is rare and its clinical manifestations are complex, making it difficult for patients to find the department they should visit. It is easy to miss diagnosis and misdiagnosis, delay the treatment time of patients, and affect the prognosis. DIAGNOSIS INTERVENTIONS: The patient was admitted to the gastroenterology department due to hepatic insufficiency. Multiple osteogenic changes were found by improved enhanced CT due to screening for causes of hepatic insufficiency, and spleen enlargement was indicated by abdominal ultrasound. Due to the involvement of multiple system problems, and follow-up of medical history, it was found that there was a history of discoloration of the distal limb in cold weather in the past 5 years. All things considered, it may be POMES. Further refinement of the bone marrow examination revealed active proliferation of granulocytes and erythrocytes. Bone marrow biopsy showed active hyperplasia, dominated by granulocytes. IFE showed IgA (type λ) and monoclonal myeloma (M) protein bands. To sum up, POMES diagnosis is considered. OUTCOMES: After the diagnosis is clear and the informed consent of the patient and his family is obtained, prednisone acetate is anti-inflammatory, lenalidomide is used to regulate immune function, liver and stomach protection treatment and bile secretion promotion are given. The patient reported improvement in liver function, significant improvement in overall and limb stiffness, and was discharged with improvement. LESSONS Although bone lesions are not typically the main manifestation of POEMS syndrome, this diagnosis should be considered when this manifestation is combined with organ enlargement, skin changes, and peripheral neuropathy. In addition, the collection of medical history is crucial, when there is a clinical manifestation and auxiliary examination does not match, the idea should be expanded according to the relevant evidence, and finally make the corresponding diagnosis.
