Abstract:
Objective To strengthen the recognition of atypical POEMS syndrome in order to improve diagnosis rate of rare cases of POEMS syndrome. Methods The diagnosis and treatment of a rare case of POEMS syndrome coexisting with Castleman disease but without M protein in serum, urine and bone marrow who was admitted to Xuanwu Hospital, Capital Medical University in November 2017 were retrospectively analyzed with review of the literature. Results The elder male was suspected with a diagnosis of POMES syndrome, but absence of monoclonal plasma cell disease that made it difficult to diagnose. Systemic PET-CT found an active metabolic lesion in left iliac bone. Although the lymph node biopsy had been performed for a diagnosis of Castleman disease, a bone biopsy was also done for a definite diagnosis. Pathological result indicated a plasmacytoma which confirmed a diagnosis of POEMS syndrome without M protein in serum, urine and bone marrow. Literature review suggested that the application of immunofixation electrophoresis was helpful to improve the diagnostic rate of POEMS syndrome. For patients with a suspected diagnosis of POEMS syndrome, bone biopsy, flow cytometry and systemic PET-CT may assist in the search for monoclonal plasma cell. Periphery neuropathy, bone lesion and treatment response were helpful in distinguishing Castleman disease coexisting with POEMS syndrome from Castleman disease without POEMS syndrome. Conclusions When a mandatory major criterion of POEMS syndrome is not sufficient, it should be actively sought, especially for patient with a suspected diagnosis of POEMS syndrome. For patients with multiple lesions, multi-site biopsies are necessary to assist in diagnosis.
