POEMS Syndrome: Clinical and Laboratory Approach Towards Diagnosis.

Polyneuropathy, organomegaly, endocrinopathy, M protein, skin changes (POEMS) syndrome is a rare multisystem paraneoplastic disorder. Here we describe a case of a 50 year old post-menopausal female who presented with chief complaints of difficulty in walking, getting up from squatting position and tingling sensation of bilateral lower limbs since 1 month. Additional unusual features in the patient included hepatosplenomegaly, endocrinal involvement in the form of hypothyroidism and elevated estradiol levels for her age. There were skin changes in the form of hyperpigmentation. M protein was not noted on serum electrophoresis but was visible on serum protein immunofixation (IgA lambda). She was investigated as a case of polyneuropathy and later a provisional clinical diagnosis of POEMS was made based on the presence of major and minor criteria. The patient was managed with methyl prednisolone, calcium carbonate and vit D3 and topical antibiotics for local infections. © Association of Clinical Biochemists of India 2021.
