Aspergillus colonization of an echinococcal cyst cavity: Case report Ekinokok kisti kavitesinde aspergillus kolonizasyonu: Olgu sunumu

Although lungs are common sites for the occurrence of saprophytic or invasive mycosis as well as hydatid cyst, aspergilloma within a hydatid cyst is a rare occurrence. A 36-year-old immunocompetent male presented with hemoptysis episodes of about 1 year duration. Chest X-ray revealed a smooth countered mass lesion located in the upper part of lower lobe of lef lung. Surgical enucleation of the cyst wall was performed. Microscopic examination showed that the laminated membranes of hydatid cyst were invaded by septated fungal hyphea oriented with acute angles consistent with aspergillus. Herein, we report such a unique coexistence of hydatid cyst and aspergilloma, and emphasize possible complications depending on the immunostatus of the patient, if the aspergillus colonization is unnoticed in resected cystectomy material.
