Abstract
This case report focuses on a 71-year old patient affected by unknown dyspnea and erythrocytosis referred by his general practitioner to our center for specialist advice after a hematological examination had excluded polycythemia vera on grounds of negative test for JAK2 V617F / exon 12 mutation. An accurate clinical history and physical examination accompanied by respiratory function tests resulted in diagnosis of JAK2 V617F mutation negative erythrocytosis, and treatment could be started. The discussion examines decisional algorithms when a polyglobulic patient is referred for diagnosis.

We are pleased to announce that we have implemented a new plugin for our journal, which will track citations from Scopus, Google Scholar, Crossref, and Europe PMC. This will allow authors to easily see how many times their work has been cited in these databases. Europe PMC also serves as a search engine and directly links to the work as indexed on PubMed and PubMedCentral, providing additional visibility. The plugin widget (see below) can be found at the bottom of each published work, and by clicking on the database symbols, authors can view the citation numbers.
