Paper text:
a case of feverish benign neutropenia occurring in a diabetic patient receiving pregabalin for peripheral neuropathy is reported .
although pregabalin - induced neutropenia is very rare , it is important to keep in mind that this drug like other anticonvulsants used for neuropathic pain , can cause severe neutropenia .
a 64-year - old woman , diagnosed with diabetes mellitus and arterial hypertension in her 50s , presented with fever and malaise .
she had been taking pregabalin for the last 3 weeks because of peripheral neuropathy . during that period
a blood count showed mild anemia ( hb 11.2 g / dl ) and leukopenia ( wbc 1.32  10/l with neutrophils 5% ) .
a buffy coat smear showed many lymphocytes and monocytes , few eosinophils and very rare neutrophils ( fig.1 , left , 400 ) .
there were rare scattered erythroblasts and selective deficiency of maturing granulocytic cells with clear predominance of promyelocytes with heavy granulation ( fig.1 , right , 1000 ) .
these laboratory and morphologic features suggested a diagnosis of benign neutropenia possibly drug - associated .
thus , pregabalin was discontinued and therapy with granulocyte colony stimulating growth factor and empirical antibiotics ( ceftriaxone and levofloxacin ) was administered .
the temporal correlation between the initiation of pregabalin and the onset of feverish neutropenia as well as the normalization of white cell count after drug discontinuation strengthened the diagnosis .
although pregabalin - induced neutropenia is very rare and its exact prevalence is so far unknown , it is important to keep in mind that this drug like other anticonvulsants used for neuropathic pain can cause neutropenia [ 14 ] . on the other hand , the morphologic features of bone marrow promyelocytes , especially the presence of a clear golgi zone and the absence of auer rods , may be helpful in distinguishing them from dysplastic or leukemic promyelocytes allowing the differential diagnosis from a malignant disorder .
key clinical messagea case of feverish benign neutropenia occurring in a diabetic patient receiving pregabalin for peripheral neuropathy is reported . 
 although pregabalin - induced neutropenia is very rare , it is important to keep in mind that this drug like other anticonvulsants used for neuropathic pain , can cause severe neutropenia .
