Cryptococcosis as a complication of therapy for sarcoidosis: a case report

Cryptococcosis is a rare complication of sarcoidosis, especially when it grows in lungs. It may escape from being diagnosed because of low prevalence and non-specific radiological presentation. Hereby, we reported an unusual case of pulmonary cryptococcosis secondary to the long-term use of glucocorticoids to treat sarcoidosis which can be misdiagnosed as progression of sarcoidosis due to the similar radiological presentation. After targeted therapy with fluconazole for 5 months, her chest computed tomography rescan revealed resolution of the pulmonary lesions.
