Aspergillus colonization of an echinococcal cyst cavity: case report

Abstract

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 left 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.

Sclerosing thymoma with numerous coarse calcifications

“…This may be due to dystrophic calcification, in which the solubility of calcification decreases as a result of severely poor blood flow, which stops CO 2 production in necrotic tissue and increases alkalinity. Although there have been cases 2 which had calcifications, there has never been one as significant as this case.…”
