Sparganosis is infection by a sparganum, the genetic term for the plerocercoid larva of a pseudophyllidean tapewarm. The majority of infections in man are caused by raw consuming of snakes and frogs in Korea. Clinically, subcutaneous mass or lump was the most frequent problem but retroperitoneal mass was very rare. We treated a case of sparganosis invading the retroperitoneal space that was diagnosed initially as soft tissue tumor.

We report herein a human sparganosis that presented confusing features in aspect of its correct identification, The patient was 35-year-old man who had a past history of eating fried frogs since 3 years prior to his first admission in 198I. Three mature Sparganum mansoni and 69 encapsulated spargana pieces were excised from his left inguinal area, left thigh and scrotum by three consecutive operations in 19 months. The encapsulated spargana were irregular in shape and size and mummified. They were identified histopathologically as degenerated spargana by no sexual organs and many calcareous bodies in the parenchyma. Differentiation of our case from proliferating sparganosis caused by Spargarrum proliferum was discussed.

Sparganosis is a parasitic infestation caused by sparganum on several species of tapeworm related to diphyllobothrium latum. We experienced a case of the sparganum infestation with giant hematoma in scrotum.

Sparganum infestation of the human body was reported over 120 cases and of the urogenital region was reported over 30 cases in korean literatures since 1924. But, infestation of the penis was reported two cases. We experienced a case of sparganosis in the penile shaft and reporte this case with the review of literature of sparganosis of the genitourinary region.

Sparganosis is an uncommon infection caused by sparganum, a migrating plerocercoid larva. Currently, various imaging modalities have been actively used for the diagnosis of sparganosis before surgery. We present a case of sparganosis arising in the subcutaneous layer of the thigh that was diagnosed only by an ultrasound examination.

The migration and distribution pattern of spargana in mouse body was observed after experimental infection through mouth. The spargana were obtained from the snake, Natrix tigrina lateralis, caught in Hoengseong-gun, Kangwon-do. A total of 28 male mice (ICR strain), 21-25g in body weight, were fed each with 5 scolices (and necks) of spargana and killed after 10 minutes to 14 days. Systemic autopsy was performed on each mouse to recover the spargana. The results are as follows: The spargana were found to penetrate into the stomach or duodenal wall of mice as early as 10 minutes after infection. They completed the penetration within 30 minutes and appeared in abdominal cavity. It was observed that spargana did not migrate tangentially along the gut wall but directly perforated the wall. After 1 hour to 1 day the majority of spargana distributed in abdominal cavity of mice except few which migrated to muscles or subcutaneous tissues. It was within 7 days that nearly all of the spargana migrated to subcutaneous tissues. Out of total 28 in number found from subcutaneous tissues, 13 distributed around neck region, 12 around trunk and other 3 on head of mice and the most common sites were submandibular and subscapular areas. There was nearly no host tissue reaction to migrating spargana. The initial length of spargana given was 4 mm in average but it increased to 12 mm after 7 days and to 35 mm after 14 days. The results suggest that spargana orally given to mice penetrate the gut wall within 30 minutes followed by escaping into abdominal cavity, and after passing through thoracic cavity or abdominal wall they finally localize in subcutaneous tissues chiefly around neck region within 7 days.

Sparganosis mansoni is a kind of parasitic infective disease, rarely seen in clinic. A case of sparganosis mansoni is reported in this article. The patient was a 25-year-old male, who came to Xiangya Hospital on September 26, 2007 because of a mass in the left cheek. A white tape-like body was found during the operation and recognized to be a live parasite. Enzyme linked immunosorbent assay of the serum revealed positivity against Spirometra mansoni. The final identification proved that the white tape-like body was Sparganum mansoni. The disease of this patient was caused by eating raw flesh of frogs infected with the Sparganum mansoni.

A case of Sparganosis mansoni, in scrotum and subcutaneous layer of suprapubic region, in a three year-old Korean child is reported. Life cycle and route of infection of Sparganum mansoni in this case are briefly discussed. Administration of these sparganums into the dog failed to identify species of Diphyllobotrium.

PURPOSE: The subconjunctival sparganosis is rare tissue helminthiasis which developed frequently in abdominal, urethral, ureteral and vertebral cases. Authors report a case of sparganosis in the subconjunctival mass. METHODS: A 51-year-old man with reddish non painful mass in his left eye on the subconjunctiva that was unresponsive to medications for 6months was evaluated and treated surgically. On surgical exploration, a white thread-like plerocercoid 0.2 x 4.7 cm in size was extracted from the subconjunctival mass and actively motile in the bottle filled with saline. It was confirmed as a typical sparganum under histologic examination. Three months after surgery, the lesion disappeared completely. RESULTS: Although rare, parasitic disease should be suspected in a palpable subconjuntival mass unresponsive to the medical treatment.

A survey on the infection status of sparganum and Gnathostoma in frogs was carried out in 11 areas in Gyeongsangnam-do and Cheonlanam-do province, a southern part of Korea. Among 626 frogs examined, 4 percent were infected with sparganum, but none with Gnathostoma. The infection rates of sparganum were variable according to the areas. Those from Kimhae, Sunchun, Jinhae, Sachun, Kosung, Keoje, and Hadong were 16 percent, 9.1 percent, 9.1 percent, 4.1 percent, 2 percent, 2 percent, and 1.5 percent respectively, but frogs from Hapchun, KwangJu, Namwon and Sanchung were not found infected. Rana nigromaculata was the only species infected with sparganum. Rana rugosa and Bombina orientalis were not infected. Sparganum was mainly found in the legs and the trunk of frog. About 92.5 percent of worms were detected in the femoral intermuscular connective tissue. Number per infected frog was in range of one to five, and 2.8 percent of frogs were infected by only one worm. The heavier the frog weight, the higher the infection rate of sparganum. In frogs of 51-60 grams, 28.6 percent were infected.
