A Case of Pulmonary Cryptococcosis with Diffuse Pulmonary Involvement of Malignant Lymphoma

Abstract

A 39-year-old male was admitted to our hospital because of cough and dyspnea. The chest x-ray revealed consolidation in the bilateral middle-lower lung fields. The diagnosis of pulmonary cryptococcosis was made by transbronchial lung biopsy of the right lung, and symptoms and cosolidation were improved transiently by treatment with anti-fungal agents. We could not find any underlying diseases despite of intensive examination during the treatment. However pulmonary involvement became larger suddenly, he died of respiratory failure. Post-mortem examination revealed malignant lymphoma invading both lungs diffusely and pulmonary cryptococcosis.
