RESUMEN
The paper describes a case of disseminated strongyloidosis in a 52-year-old woman living in Volgograd. Filariform and. rhabditiform larvae of the nematode Strongyloides stercoralis were found when analyzing her urine, sputum, and feces. She had been followed up and treated for duodenal ulcer for more than 15 years. During that time, the patient periodically underwent radiographic and ultrasonic studies and clinical and biochemical blood tests. Fecal tests were not been carried out. This case could convince that there was a risk for human strongyloidosis in the arid region having a temperate climate in European Russia and when timely detection of invasion and specific treatment were not performed, there might be disseminated strongyloidosis. The reason for late diagnosis was epidemiological history (possible contact with soil) underestimation and improper-patient examination.
