OBJECTIVE: To investigate the formative mechanisms of the fibrous capsule around hepatic and splenic hydatid cyst. METHODS: HE stain was used to observe the histopathologic changes of the fibrous capsules around hepatic and splenic hydatid cysts and the adjacent parenchyma. The expression of collagen IV, fibronectin (FN), laminin (LN), transforming growth factor-beta1 (TGF-beta1) and tumor necrosis factor-alpha (TNF-alpha) were detected by using immunohistochemistry or in situ hybridization in fibrous capsules around 40 hepatic hydatid cysts and 15 splenic hydatid cysts including adjacent parenchyma. RESULTS: A special delaminated phenomenon was observed in the fibrous capsules around hepatic hydatid cysts. Granuloma-like pathologic changes were found in the fibrous capsules near worm and there were many depressed Glisson capsules and hepatic vein system in the fibrous capsules near hepatic parenchyma while these phenomena could not be observed in splenic hydatid cysts. All parameters were highly expressed in the fibrous capsules near hepatic parenchyma and the difference between the two fibrous capsules was significant (P<0.01). CONCLUSION: The mechanisms of forming fibrous capsule around hepatic and splenic hydatid cysts are different. The fibrous capsule around hepatic hydatid cyst is a granuloma-like structure, covered by the pressed Glisson system and hepatic vein system with a small gap between them; while the fibrous capsule around splenic hydatid cyst is formed by granuloma-like tissue covering the worm and there is no gap between the capsule and the splenicparenchyma.

Hydatid cyst is a significant health problem in endemic regions. Although progress has been made in medical treatment and interventional radiology techniques, surgery is currently the treatment of choice. The hydatid cysts are known to occur at several unusual sites in the body. With increasing experience in laparoscopy and retroperitoneoscopy, attempts have been made to offer the advantages of minimal access procedures to hydatid disease patients. We present a case report of such a patient whose retroperitoneal hydatid cyst was removed endoscopically.
