Case Report: Hydatid Disease as a Potential Cause of Leukocytoclastic Vasculitis in Endemic Regions.

Leukocytoclastic vasculitis (LCV) is a type of vasculitis that affects small vessels and is commonly associated with infections, malignancies, drugs, and autoimmune diseases. In this case, a 75-year-old female patient presented with clinical signs of LCV, and after ruling out common etiologies, hydatid disease (HD) emerged as a potential cause. This case highlights the importance of considering parasitic infections, particularly HD, in the differential diagnosis of LCV, especially in regions where these infections are endemic and in patients exposed to relevant environmental risk factors.
