ABSTRACT We report an uncommon case of a primary Echinococcus cyst that developed in the subcutaneous tissue of the right popliteal fossa, at the spot of a previous wasp sting, suggesting the possibility of an unusual transmission of the eggs by insects. This unusual presentation was initially considered as a Baker cyst until parasytological results verified Echinococcus hydatidosus, the larval form of Echinococcus granulosus, as diagnosis. However, the most common path of Echinococcus granulosus infection is through contact with a definitive host or by ingestion of ova through contaminated water or food. Transmission by insects should also be reconsidered in endemic areas.

    ABSTRACT: ?Increasing world population worsens the serious problem of food security in developing countries. On the other hand in industrialized countries, where the problem of food security is of minor concern, health problems related to food refer to 2 main factors: food safety and environmental sustainability of food production. For these reasons, new ways must be found to increase yields while preserving food quality, natural habitats, and biodiversity. Insects could be of great interest as a possible solution due to their capability to satisfy 2 different requirements: (i) they are an important source of protein and other nutrients; (ii) their use as food has ecological advantages over conventional meat and, in the long run, economic benefits. However, little is known on the food safety side and this can be of critical importance to meet society's approval, especially if people are not accustomed to eating insects. This paper aims to collect information in order to evaluate how insects could be safely used as food and to discuss nutritional data to justify why insect food sources can no longer be neglected. Legislative issues will also be discussed.

    ABSTRACT: Hydatid cyst is the disease of liver and lungs and is common in some regions especially sheep rearing countries of the world, but this disease may occur in any part of world and anywhere in the body. This report presents primary hydatid cysts located in intramuscular region of left side of the abdomen. A 54-year-old female patient from central India, farmer by occupation, non vegetarian by diet came with chief complaints of a painless mass in the left iliac fossa, gradually increasing in size over a period of 6 months. Superficial ultrasound revealed a lesion resembling a hydatid cyst. Surgical excision was done without injuring the cyst. Diagnosis was confirmed on histo-pathological examination and was compatible with a hydatidcyst. Ahydatid cyst should be considered in the differential diagnosis of subcutaneouscystic lesions, it should be excised totally, with an intact wall and postoperative albendazole should be given to avoid recurrence.
