Abstract
Human sparganosis is a food-borne zoonosis mainly caused by the plerocercoid belonging to the genus Spirometra. The most common clinical sign of sparganosis is a subcutaneous mass in the trunk including abdominal or chest wall. The mass may be mistaken for a malignant tumor, thereby causing difficulty in terms of diagnosis and treatment. A 66-year-old woman visited our clinic for the removal of a lipoma-like mass. It was movable, hard, and painless. We identified 2 white mass, measuring 0.2×4 cm and 0.2×1 cm. Pathologic findings indicated the white mass was a sparganum. She recalled having eaten a raw frog approximately 60 years before. A 35-year-old who lived North Korea was also presented to our clinic with an asymptomatic nodule on her abdomen. Intraoperatively, we found sparganum approximately 24 cm size. Subcutaneous masses are associated with clinical signs of inflammation or they may mimic a soft tissue neoplasm. While the incidence rate of sparganosis has decreased with economic development and advancements in sanitation, surgeons still encounter patients with sparganosis in the clinical setting. Therefore, a careful history is required in order to diagnose sparganosis.

Abstract
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.

Abstract
In determining the etiology of eosinophilia, it is necessary to consider the type of patient, including previous travel and exposure history, comorbidities, and symptoms. In this review, we discuss the approach to the patient with eosinophilia from an infectious diseases perspective based on symptom complexes.

Abstract
Human sparganosis is a food borne zoonosis caused by the plerocercoid larvae (spargana) of various diphyllobothroid tapeworms of the genus Spirometra. Human infections are acquired by ingesting the raw or undercooked meat of snakes or frogs, drinking untreated water, or using raw flesh in traditional poultices. More than 1600 cases of sparganosis have been documented worldwide, mostly in east and southeast Asia. Sporadic cases have been reported in South America, Europe, and Africa, and several cases have been described in travellers returning from endemic regions. Epidemiological data suggest that the increased effect of sparganosis on human health is because of greater consumption of raw meat of freshwater frogs and snakes. This Review provides information about the Spirometra parasites and their lifecycles, summarises clinical features, diagnosis, and treatment of human sparganosis, and describes geographical distribution and infection characteristics of Spirometra parasites in host animals.

Abstract
Sparganosis is an infestation caused by a tapeworm belonging to the genus Spirometra. We describe a surgically confirmed case of sparganosis in several organs including the breast, both lower extremities, anterior chest wall, inguinal area, and the psoas and gluteus muscles. Mammography, ultrasonography, and MRI imaging findings for our patient were characteristic of sparganosis. Ultrasonography revealed multiple elongated tubular hypoechoic structures with surrounding increased echogenicity. Mammographic findings included tortuous, lobular, and tubular densities. Short tau inversion recovery (STIR) MR images contained several elongated tubular tracts of high signal intensity. These imaging features were highly consistent with pathology results.

Abstract
Sparganosis of the breast is an uncommon disease, but should be considered in the differential diagnosis of unusual and suspicious breast masses. A history of ingesting contaminated water and direct ingestion of snakes and frogs may help in differential diagnosis of the mass. Complete surgical removal is the treatment of choice and provides a definite diagnosis. We report a case of multiple axillary lymph node sparganosis. It was first considered as an axillary metastasis of breast cancer because a newly axillary mass appeared in follow-up radiologic study after neoadjuvant chemotherapy. We performed curative breast cancer surgery and sparganosis was confirmed by extracting the worm during axillary dissection.
