Distribution of Sparganum mansoni in 7 species of terrestrial snakes in Wonju City was surveyed. All kinds of snakes were found to be served as intermediate hosts of this larval worm except Elaphe schrenkii which has already been recorded as important host. Authors believe that Zamenis spinalis was firstly recorded as intermediate host of Sparganum mansoni in Korea. Some aspects of infection status, host-parasite relations and sources of human infection were briefly discussed.

To observed whether the specific IgG antibody test using ELISA was useful in diagnosis of presently ill patients of paragonimiasis, a total of 95 sera were tested. The sera were collected from 21 egg positive cases, 8 from positive reactors of intradermal test, 7 from Clonorchis infected, 9 from other parasitic diseases and 50 from apparently non-infected cases. By the result, the sensitivity of the test was 86% and the specificity was 100%. There were no cross reactions between Paragonimus antigen and other parastic infections. Specific IgG antibody test by micro-ELISA was concluded to be useful for mass screening of the presently ill paragonimiasis in the field.

Sparganosis is a parasite infestation caused by the larval stage of Spirometra erinacei. Ingestion of raw or undercooked flesh of numerous intermediate hosts results in human infection. Sparganum infestation of human body was reported over 120 cases including urogenital lesions in Korean literatures since 1924. But, no case of sparganosis in the spermatic cord was reported until now. We experienced a case of sparganosis in the spermatic cord.

Human sparganosis in Korea was discussed on the bases of five human cases experienced by the present authors and 58 case records already reported by many previous authors, in aspects of epidemiology and clinical features. Sparganosis is not infrequent tissue helminthiasis now in Korea and the incidence has been evidently increased during past 10 years. It might be interpreted that improved medical delivery system and health care exposed the hidden but prevalent disease. The distribution of sparganosis in Korea is apparently subdivided into three major endemic areas; Kyunggi Do, Kyungsang Do and Hamkyung Nam Do. Although scanty in other areas of Korea, the distribution of this disease is presumably throughout the whole peninsula of Korea except Cheju Do. The majority of human cases of sparganosis in Korea has revealed raw consuming of snakes for treatment of tuberculosis, syphilis and joint pain, for tonics and for the belief of special nutrition among very limited group of Korean population. Because of this kinds of mode of infection, comprising four fifths of all cases, the majority of cases detected were male adult consisting of about 70% of total cases. And drinking of untreated water in rural area where no protective, sanitary measures for water sources were provided in the past, seems another important causes of infection especially in women and children in Korea. Thus it may be concluded that sparganosis in Korea is concluded by eating of infective stages per os voluntarily or involuntarily, but not through the direct invasion. Clinically, subcutaneous mass or lump was the most frequent problem in those patients and those masses were associated with inflammatory signs. By the anatomical location of the lesion, some peculiar manifestations could be developed as in orbital, abdominal, urethral, ureteral and vertebral cases. And the lesions could be complicated by haemorrhage or abscess formations. The larval worms hitherto collected in Korea has been identified tentatively as Sparganum mansoni because neither branched larvae nor Sparganum proliferum were ever reported.

Sparganosis is an infection caused by the migrating larvae of the cestode genus Spirometra. The most common clinical presentation of a sparganosis is a slow-growing, sometimes migratory, sub-cutaneous mass. In this report, a case of eosinophilic panniculitis by sparganum in a Korean woman is presented. The diagnosis was confirmed from the histopathologic findings, the micro-ELISA tests and a living sparganum derived from the patient while excising the new lesion

Sparganosis is a parasitic infestation caused by the larval stage of Spirometra erinacei. Human infection results from ingestion of raw or undercooked flesh of any of the numerous intermediate hosts and from application of such flesh as poultices. Sparganosis have been reported from orbit and bulbar conjunctiva. But, urogenital infestation of Sparganum is rarely observed. We report an additional case of the sparganum infestation in the right scrotum.

Spargana were collected from human and frogs in Liaoning and Hubei Provinces, China. PCR amplification and direct sequencing of A cox1 fragment was PCR-amplified from genomic DNA extracted from 7 specimens (5 from humans and 2 from frogs). The cox1 fragment (390 bp) showed 97–100% similarity to the reference sequence of S. erinaceieuropaei and 88–89% to the reference sequence of S. decipiens. There were 1–12 bases different between these worms, but no obvious genetic variation (0–3.3%) to the references. There was little difference of cox1 gene between sparganum samples of humans and frogs (1–3%). This study is the first report on S. erinaceieuropaei spargana from humans in Liaoning and Hubei Provinces.

Sparganosis is a parasitic infection caused by the sparganum, the plercercoid of the genus Spirometra. The preoperative diagnosis of breast sparganosis is difficult in most cases because it is a rare parasitic infection less than 2% of all cases. We report a 62-year-old woman case of breast sparganosis that were confirmed by surgical removal of worms from the right breast. The radiologic images of the patient also revealed characteristic features of breast sparganosis. The patient described the migrating palpable breast mass, which strongly suggested the possibility of breast sparganosis. The treatment of choice and confirmative diagnosis for sparganosis are complete surgical extraction of the sparganum irrespective of infected site. Inspection of the mass site with detailed medical history and radiological examinations are important for preoperative diagnosis of sparganosis patients.

Based on 16 cases of human sparganosis, a histopathological study was made. There was a striking similarity among histological features of sparganosis involving different tissues. The histological change of the affected tissues was characterized by a necrotizing and granulomatous inflammation with or without worm parasite in the lesions. There was also a remarkable polymorphonuclear leukocytic mobilization, predominantly of eosinophils, plasma cells and lymphocytes in and near the lesions. Tunnel formation lined by palisading histiocytes was another charateristic feature of the host tissue reaction. These findings were quite distinguishable from those of cysticercosis which were more localized and self-limited. Several features that were prominent in section slides of sparganum worm parasite were also noted. Laminated calcospherules found in the cytoplasm of the proliferating macrophages and giant cells were of diagnostic value of sparganosis in the absence of the worm, particularly when these were accompanied with tunnel-like lesion in the host tissue.

Sparganosis is a kind of parasitic skin disease caused by sparganum, the plerocercoid larvae of the taper worm of the genus Spirometra. Sparganosis usually manifests as migrating or fixed subcutaneous nodules; therefore, it should be differentiated from lipoma, cysts, and cutaneous malignancies. Although the final diagnosis of sparganosis in humans depends on the identification of the worm in an infected tissue, suspicion for the presence of the parasite and careful history taking are important before making the diagnosis. However, it might be difficult for a clinician to suspect the existence of sparganosis because the incidence of this disease is extremely low. Therefore, an effective method for differentiating sparganosis from other skin disorders is needed. We suggest that ultrasonography could be an answer to this problem, on the basis of our experience of a case of cutaneous sparganosis in a 65-year-old woman showing very characteristic ultrasonographic findings.
