Polycythemia vera is a rare myeloproliferative disease. Cutaneous symptoms are uncommon. We report about a 72-year-old female patient with JAK2(V617F) -positive polycythemia who developed peripheral sensorimotor axonal neuropathy and erythromelalgia. Possible causes and treatment are discussed.

Polycythemia is rarely associated with pheochromocytoma. A patient with a 22-year history of malignant pheochromocytoma is presented in whom major complications developed as a result of long-standing polycythemia, apparently due to secretion of erythropoietin by the tumors. Despite attempts to reduce tumor burden by surgery, chemotherapy, and large doses of I-131-metaiodobenzylguanidine, polycy...

PATIENT Female, 64 FINAL DIAGNOSIS: Polycythemia rubra vera Symptoms: Burning pain • cramps • hypesthesia • itching • paresthesia MEDICATION - Clinical Procedure: - Specialty: Neurology. OBJECTIVE Unusual clinical course. BACKGROUND The association between polycythemia vera and peripheral neuropathy has been described previously but only as a late complication and only with sensory axonal...

OBJECTIVE To evaluate the various clinical and laboratory parameters of Polycythemia vera and idiopathic erythrocytosis in order to differentiate between two entities at the Aga Khan University Hospital. METHODS Twenty six patients of polycythemia vera and 34 patients of idiopathic erythrocytosis were analyzed with respect to clinical features and laboratory findings. RESULTS Patients with ...

Polycythemia vera is a chronic progressive myeloproliferative disease characterized by increased circulating red blood cells, and the hyperviscosity of the blood can lead to an increased risk of arterial thrombosis. In a previous survey regarding postoperative outcomes in polycythemia vera patients, an increased risk of both vascular occlusive and hemorrhagic complications have been reported. A...

Metanephric adenoma (MA) is a rare neoplasm that acounts for 0.2% of adult renal neoplasms. MAs are typically discover incidentally during detailed examinations for nonspecific symptoms such as abdominal or flank pain, hematuria, fever and palpable abdominal mass. Additionally, polycythemia has occasionally been reported as well. Herein we describe a case of metanephric adenoma which was an inc...

Very little is known about the influence of polycythemia on oxygen transport during exercise. We studied chronically instrumented dogs trained to run on a treadmill before and after their hematocrit had been increased by isovolemic exchange transfusion with packed red blood cells. With normovolemic polycythemia, cardiac output fell in a linear fashion as hematocrit was increased to 65%, but the...
