Pulmonary Cryptococcosis in a Human Immunodeficiency Virus Negative Patient: A Case Report.

Cryptococcosis is a major life-threatening fungal infection in patients with severe HIV infection and other immunocompromised states. Lung and central nervous system (CNS) are the most commonly involved organs in disseminated cryptococcosis. Others include skin, prostate, medullary cavity of bones, eyes, heart, liver, etc. Pulmonary cryptococcosis may be misdiagnosed because of comparatively nonspecific clinical and radiological features. We report the case of a 61-year-old male patient who is a known case of gastroesophageal reflux disease (GERD), myasthenia gravis, and steroid-induced diabetes mellitus. He was diagnosed with gangrenous cholecystitis at another institution but refused surgery. At our hospital, he experienced loss of consciousness in the out-patient department (OPD) and was therefore admitted for further evaluation where he was found to have pulmonary cryptococcosis and pancytopenia. Pulmonary cryptococcosis is usually found in HIV-positive immunosuppressed patients. However, sometimes it is also seen in HIV-negative patients, and they tend to have a good prognosis with adequate treatment.
