A Solitary Abscessed Hydatid Cyst of the Buttock: A Rare Case.

ABSTRACT

The hydatid cyst is a cosmopolitan parasitic infection caused by tapeworms of the genus Echinococcus and is a major public health problem in developing countries. Solitary hydatid cysts located in the buttocks are very rare, and the unusual location of the cyst can aid in the differential diagnosis of subcutaneous masses in this area, particularly in endemic areas. In this report, we present the case of a 39-year-old man who was admitted to the emergency department with a painful, abscessed cyst in the buttock region. The cyst was completely excised, and histopathological examination confirmed the diagnosis of a hydatid cyst. Further investigations did not reveal any other locations. Although the buttock region is an extremely rare site of infection for a hydatid cyst, it should be considered in cystic lesions, especially in endemic areas.
