Large mass-like pulmonary cryptococcosis: report of 2 cases.

Abstract

Pulmonary cryptococcosis, a less common fungal infection, frequently reveals nodular lesions (single or multiple) and patchy infiltrations (alveolar or interstitial) on chest X rays. A large mass-like pattern is less common. Here we report 2 cases of pulmonary cryptococcosis with negative bronchoscopic findings. One patient received a right lower lobectomy under the impression of malignancy; the other received a transthoracic needle aspiration, and numerous cryptococci were found by India ink preparation. Thus, pulmonary cryptococcosis should be included in the differential diagnosis of a mass lesion. A brief review of the literature is also included about diagnostic approach and management of pulmonary cryptococcosis.
