Seroprevalence of the IgG antibodies for Clonorchis sinensis, Paragonimus westermani, Taenia solium metacestode (cysticercus), and Spirometra erinacei plerocercoid (sparganum) was measured using enzyme-linked immunosorbent assay (ELISA) in sera of patients in Korea from 1993 to 2006. A total of 74,448 specimens referred nationwide from 121 hospitals revealed an IgG positive rate of 7.6% for the...

Primary malignant tumors of the maxillary sinuses are rare. The present study reports the case of a maxillary sinus adenocarcinoma that was misdiagnosed as a frog sparganum infection, and discusses the differential diagnosis between the two diseases. The patient was ultimately diagnosed with a carcinoma of the left maxillary sinus that presented as a progressive mass in the left eye and the max...

Sparganosis is a parasitic infestation of human by plerocercoid larvae. Sparganum is usually reported to be found in the subcutaneous tissues as well as other organs, including scrotum. However, testicular sparganosis is extremely rare, because of strong capsule of tunica albuginea. An urban-living 54-yr-old Korean man presented with left scrotal pain for 6 yr.

Using both traditional methods and broad-range 18S ribosomal DNA (rDNA) polymerase chain reaction, we examined 2 cases of lethal cestodiasis, in which the disease agent had been poorly identified or misidentified. In one case, involving a patient with AIDS, we identified the human dwarf tapeworm, Hymenolepis nana, as a cause of aberrant metastatic larval disease. In the second case with similar...

Cerebral sparganosis (CS) is a parasitic infection caused by the larva of Spirometra mansonoides. Rarely it can affect the human brain. We report the case of a 24-year old man from Paraguay who suffered from seizures and headache for one year. A frontal tumor was diagnosed by CT-scan and was subsequently resected. The pathological examination revealed a larva with Sparganum characteristics. The...

In the present study, the cestoid Pterobothrium crassicolle Diesing, 1850 (Trypanorhyncha), was observed parasitizing specimens of the violet goby (Gobioides broussonnetii Lacepède, 1800) collected from the estuary of the Paracauarí River on Marajó Island in the north of the Brazilian state of Pará, between January 2009 and December 2010. Tissue samples were analyzed, which led to identificatio...
