Hydatid Cyst of Unusual Sites, An Experience at Chandka Medical College Larkana

Abstract

Background: Hydatid cyst occurs throughout world but more in endemic areas where human beings live in close 
contact with cattle and dogs. Common organs affected by hydatid cyst are liver and lung but rarely occurs in other 
organs as well. 
Objective: To evaluate the unusual sites of hydatid cyst in human beings, this will help the clinicians in early 
diagnosis and management. 
Study Design: Observational  
Place & Duration: The study was conducted in the Department of Pathology, Chandka Medical College Larkana 
from January 1995 to December 2009. 
Patients & Methods: Total of 191 patients, admitted in various hospitals of Larkana, and operated for hydatid cyst 
or incidental findings at hisptopatholgical examination were included. All the fixed biopsies were cut into 
representative tissue blocks, processed, stained for haematoxylin and eosin and examined under light microscope. 
Results: Total of 191 cases of hydatid cyst were received in 15 years, out of which 119 (62.3%) cases occurred in 
liver with mean age 41.27 years +  16.27 SD, 44 (23%) in lung with mean age 44.04 +  15.81 SD and remaining 28 
(14.7%) in other uncommon organs. 
Conclusion: The presence of hydatid cyst in uncommon sites in Larkana is 14.7%, hence possibility of hydatid cyst 
in almost every organ of the body should be suspected.
