ABSTRACT

Subcutaneous localization of an hydatid cyst is quite rare, and is found in literature in the form of case presentations. Other points worthy of attention are the lack of other foci in the majority of these cases, and the negative results of serology. In this study, two primary subcutaneous hydatid cyst cases, one in the facial area (53-year old female) and the other on the back (37-year old female), have been examined with reference to literature. In both cases, no other foci were determined, and the hydatid cyst serology was negative. When these two cases and the cases in literature are studied, it can be said that the hydatid cyst grows faster than previously known. It is noteworthy that, generally, in atypically localized cyst hydatids, there are no other foci (liver and lungs) and the serology is negative. This shows that the etiopathogenesis of the disease is not fully understood as yet. (Turkiye Parazitol Derg 2013; 37: 219-21)
