Pulmonary cryptococcosis in an immunocompetent patient—A case report

Abstract

Cryptococcosis is an infection caused by fungi that belong to the genus Cryptococcus. There are several species of Cryptococcus, but two species-Cryptococcus neoformans and Cryptococcus gattii-cause nearly all cryptococcal infections in humans. Cryptococcosis is one of the most common fungal infections in Brazil and becomes even more important after the onset of the AIDS epidemic. The lung is the main gateway, and also is the most common site, with diverse clinical manifestations ranging from an asymptomatic to severe pneumonia. When symptommatic, most patients present with fever and cough with expectoration or hemoptysis. The most common radiological findings in immunocompetent patients are located images of masses and nodules, while immunosuppression shows interstitial infiltrates and diffuses interstitial opacity. This is a case report of a patient in the third decade of life with breathing-dependent pain at the base of the left hemithorax, who has radiological examination of a mass in the left lung base in contact with the pleura mimicking malignant lung. Lobectomy was performed, as well as the pathological diagnosis of cryptococcosis.
