The tongue is a rare site of localization of cystic echinococcosis. We report a 3-year-old patient with cystic echinococcosis of the tongue demonstrated by histopathology. The cyst of the tongue was surgically removed. The tongue lesion led us to find additional liver and lung cystic lesions that were successfully treated with albendazole therapy.

Mexico is considered a virtually free region of cystic echinococcosis. Almost all case reports within the country involve immigrants or traveling patients. This manuscript presents a Mexican-native human echinococcosis that developed in the setting described below. Review of current evidence suggests that this infection has been underestimated.

The report presents two cases where diagnosis of alveolar echinococcosis was confirmed by Echinococcus multilocularis and Echinococcus granulosus PCR. The extrahepatic osseous involvement and the absence of initial hepatic involvement are unusual in both cases. Due to limitations of serological interpretation, PCR was useful to diagnose atypical echinococcosis.

Cardiac involvement in hydatid cyst disease is uncommon, occurring in approximately 2% of hydatid cases. Two cases of cardiac hydatid cysts with negative serologic tests are reported herein. In Case 1, the patient underwent surgery to remove cysts from the liver and 10 years later presented with symptoms and signs of ischaemic heart disease. In Case 2, the patient first underwent surgery to rem...

Echinococcosis is one of the diseases common to humans and animals worldwide and its metacestode form Echinococcus granulosus is the cause of disease. Diagnosis based on clinical symptoms is a problem. However, using serological methods such as ELISA, specific antibodies can be determined. Based on the medical and economic importance of the disease, this study aimed to undertake a serological s...
