Objective: To describe the first reported case of a patient with POEMS syndrome (polyneuropathy, organomegaly, endocrinopathy, monoclonal gammopathy, and skin changes) in conjunction with the endocrinologic manifestation of panhypopituitarism due to a large clinically nonfunctioning pituitary adenoma. Methods: We present the clinical, laboratory, and radiologic details of the case and review the relevant updated literature. Results: A 48-year-old man with hypopituitarism and progressive polyneuropathy presented to an outside hospital with confusion and diaphoresis. He also had diffuse lymphadenopathy, monoclonal gammopathy, and skin lesions consistent with a diagnosis of POEMS syndrome. Cytopathologic study of a lymph node showed findings consistent with Castleman disease. A large suprasellar mass was found to be the cause of the hypopituitarism. Conclusion: POEMS syndrome is a rare paraneoplastic condition, commonly associated with Castleman disease, that manifests with progressive distal polyneuropathy and a monoclonal plasma cell disorder, often accompanied by endocrinopathy, organomegaly, skin changes, sclerotic bone lesions, ascites, erythrocytosis, and thrombocytosis. Our current patient had all 5 classic features of POEMS syndrome along with some diagnostic elements of Castleman disease, sclerotic bone lesions, and thrombocytosis. To our knowledge, this is the first known reported case of a patient whose endocrinologic manifestation of POEMS syndrome was panhypopituitarism attributable to a large clinically nonfunctioning pituitary adenoma.
