A nasopharyngeal human infestation caused by Linguatula serrata nymphs in Van province: a case report.

The reason for the presentation of this case is that Linguatula serrata, a parasite rarely encountered in humans, was found in a patient in Van province. The patient, who was 26 years old, lived in Erciş a town in Van province, East Turkey. She was admitted to the Outpatient Clinic of Infectious Diseases of Erciş Government Hospital with a complaint of coughing a few worms about 4 cm long from the oral cavity, and also sore throat, partial voice loss and vomiting. The polyclinic doctor suspected that the worm was a parasite but he could not make a diagnosis, and the patient was referred to Health Research and Training Hospital, Yüzüncü Yıl University. The parasite was examined in the Parasitology Laboratory and it was observed that this parasite was the nymph of L. serrata whose mouth was surrounded with four hooks and had approximately 90 body segments with small hooks. No medical treatment was given to the patient except that gargling with saline solution was recommended. As a result, we think that physicians should consider L. serrata infestation in patients applying to health foundations with complaints such as pharyngitis accompanied by pharyngeal pain, coughing, sneezing and vomiting.
