Sparganosis is an infection with a parasitic tapeworm larva that occurs by eating infected foods or drinking contaminated water. The larvae can migrate to a tissue or muscle in the chest, abdominal wall, extremities, eyes, brain, urinary tract, pleura, pericardium, spinal canal, or scrotum. Herein, we report a 5-month old infant with scrotal sparganosis who was initially suspected to have a scrotal inflammatory mass with a history of applying raw frog meat into the umbilicus. Preoperative ultrasound examinations and computed tomography (CT) scanning misdiagnosed the mass as a scrotal teratoma. The scrotal mass was surgically removed, and the histopathology proved it to be scrotal sparganosis. This case displays the youngest patient ever reported with scrotal sparganosis, and the first description of CT characteristics of scrotal sparganosis. A detailed medical history is necessary for patients with scrotal masses suspected of sparganosis. In addition, ultrasound and CT examinations are helpful to rule out other causes of a scrotal mass.

Cerebral cysticercosis is the most common worldwide parasitic infection of the central nervous system. Intraventricular involvement is apparent in 15% to 28.8% of cases with neural compartment infestation.' Although different forms of the disease (parenchymatous, subarachnoid, and mixed form ) have been treated successfully with chemotherapy, direct surgical excision of simple cystic lesions appears to be an adequate primary therapeutic strategy in the majority of intraventricular forms. In recent years, however, some authors have advocated the use of anthelmintic treatment in all cases of intraventricular cysts so that surgical procedures of the posterior fossa and their potential complications can be avoided. The strict definition for managing the spectrum of intraventricular infestation remains controversial. We present our experience in the treatment of a patient with primary isolated intraventricular cysticercosis.

Cutaneous larva migrans (CLM) is a rare serpiginous cutaneous eruption caused by accidental penetration and migration in the skin with infective larvae of nematode that normally do not have the human as their host. Although CLM has a worldwide distribution, the infection is most frequent in warmer climates. More recently, they have been increasingly imported from the tropics or subtropics by travelers. We experienced two patients who had pruritic serpiginous linear eruption in their skin for a few weeks after traveling to the endemic areas (Brazil and Thailand, respectively). After the treatment with albendazole, the skin lesions resolved with post-inflammatory hyperpigmentation. We report herein two cases of cutaneous larva migrans successfully treated with albendazole.

Three cases of cutaneous larva migrans (CLM) were diagnosed in a returnee from a trip to Thailand and in 2 domestic farmers during July and September, 2003. The linear and serpiginous skin lesions on the lower extremities were presented in all 3 cases. Routine laboratory findings were normal. In the imported case, a 650 x 30 micrometer sized filariform nematode larva, presumably a species of hookworm, was detected in the lesion. All cases were treated with 400 mg albendazole once daily for 3-5 days, and their skin lesions gradually improved. In the present study, a causative agent of CLM was isolated for the first time in the Republic of Korea. Moreover, we speculate that CLM is prevalent in farmers who are in frequent contact with soil in the Republic of Korea.

6.Is it necessary to take anthelmintics every year in Korea?
Journal of the Korean Medical Association 2018;61(3):198-204
Is it necessary to intake anthelmintics every year in Korea? To answer to this question, the recent nation-wide egg positive rate of the intestinal nematodes in Korea was presented. The anthelminthics which are purchasable without physician's prescription were also introduced with their pharmacological reaction and indication. The egg positive rate of Ascaris lumbricoides in 2012 was 0.025%. Those of Trichuris trichiura and Enterobius vermicularis were 0.27% and 0.004%, respectively. In 2018, purchasable anthelmintics without physician's prescription in Korea were albendazole and flubendazole only. Those two anthelmintics were derivatives of benzimidazole that may cause some side effects such as hepatitis, increase of hepatic enzymes, granulocytopenia, or pancytopenia. These anthelmintics showed excellent effect to ascariasis; while, they are not sufficient to treat trichuriaiss. For treatment of enterobiasis, repeated taking 3 times with 3 weeks interval and mass treatment of the family of egg positive person are required. In conclusion, it is not necessary to take anthelmintics every year without specific diagnosis because of negligible egg positive rate of intestinal nematodes and complicated therapeutic module for enterobiasis. There was no specific symptom of ascariasis or trchuriasis if worm burden is not high. The common symptoms of enterobiasis were pain or itching at the perianal area, sleep difficulty, or diarrhea. If intestinal nematode infection is suspected, stool examination or perianal swab should be done before prescribing anthelmintics.

8.Historical Overview of Taenia asiatica in Taiwan.

The Korean Journal of Parasitology 2013;51(1):31-36
An overview of the epidemiological, biological, and clinical studies of Taenia and taeniasis in Taiwan for the past century is presented. The phenomenal observations that led to the discovery of Taenia asiatica as a new species, which differ from Taenia solium and Taenia saginata, are described. Parasitological surveys of the aborigines in Taiwan revealed a high prevalence of taeniasis, which might be due to the culture of eating raw liver of hunted wild boars. Chemotherapeutic deworming trials involving many patients with taeniasis were discussed. Praziquantel was found to be very effective, but sometimes complete worms could not be recovered from the feces after treatment, probably due to the dissolution of the proglottids. Atabrine, despite some side effects, can still be used, in properly controlled dosages, as the drug of choice for human T. asiatica infection if we need to recover the expelled worms for morphological examinations. Research results on the infection of T. asiatica eggs from Taiwan aborigines in experimental animals were also noted. Since the pig serve as the natural intermediate host of T. asiatica and the predilection site is the liver, a differential comparison of other parasitic pathogens that might cause apparently similar lesions is also presented.

Human toxocariasis is a helminthozoonosis due to the migration of Toxocara species larvae through human organism. Humans become infected by ingesting either embryonated eggs from soil (geophagia, pica), dirty hands or raw vegetables, or larvae from undercooked giblets. The diagnosis relies upon sensitive immunological methods (ELISA or western-blot) which use Toxocara excretory-secretory antigens. Seroprevalence is high in developed countries, especially in rural areas, and also in some tropical islands. The clinical spectrum of the disease comprises four syndromes, namely visceral larva migrans, ocular larva migrans, and the more recently recognized "common" (in adults) and "covert" (in children) pictures. Therapy of ocular toxocariasis is primarily based upon corticosteroids use, when visceral larva migrans and few cases of common or covert toxocariasis can be treated by anthelmintics whose the most efficient appeared to be diethylcarbamazine. When diagnosed, all of these syndromes require thorough prevention of recontamination (especially by deworming pets) and sanitary education.

Human alveolar echinococcosis (AE), a hepatic disorder that resembles liver cancer, is a highly aggressive and lethal zoonotic infection caused by the larval stage of the fox tapeworm, Echinococcus multilocularis. E. multilocularis is widely distributed in the northern hemisphere; the disease-endemic area stretches from north America through Europe to central and east Asia, including northern parts of Japan, but it has not been reported in Korea. Herein, we represent a first case of AE in Korea. A 41-year-old woman was found to have a large liver mass on routine medical examination. The excised mass showed multinodular, necrotic, and spongiform appearance with small irregular pseudocystic spaces. Microscopically, the mass was composed of chronic granulomatous inflammation with extensive coagulation necrosis and parasite-like structure, which was revealed as parasitic vesicles and laminated layer delineated by periodic acid-Schiff (PAS) stain. Clinical and histologic features were consistent with AE. After 8 years, a new liver mass and multiple metastatic pulmonary nodules were found and the recurred mass showed similar histologic features to the initial mass. She had never visited endemic areas of AE, and thus the exact infection route is unclear.
