Abstract
SESSION TITLE: Chest Infections SESSION TYPE: Original Investigation Poster PRESENTED ON: Wednesday, November 1, 2017 at 01:30 PM - 02:30 PM PURPOSE: Pulmonary cryptococcal infection is commonly seen in immunocompromised patients (ProPts), although immunocompetent patients (PePts) may also be infected. Our aim is to describe the clinicopathologic features of pulmonary cryptococcosis METHODS: We reviewed the clinicopathologic data of 21 patients with pulmonary cryptococcosis who were admitted to our hospital from 2008 to 2016. It was pathologically proven in all patients RESULTS: The patients were 14 ProPts and 7 PePts. Among 14 ProPts, it was composed of 5 cancer patients, 4 diabetes mellitus, 3 hematologic malignancy, 1 post-transplanted, and 1 rheumatoid arthritis. Mean patient age was 62 years, but, age of PePts was lower (mean age : 50). Male to female ratio was 1:1 in all patients. But, male ratio was more in PePts (71.4%) than ProPts (42.9%). Two-thirds of patients were asymptomatic. The pulmonary lesion was incidentally detected in health medical examination or during follow-up radiology of previous disease. Lesions were more common in lower than upper lung (5 pts, 71.4%) of PePts, but common in upper than lower (8 pts, 64.2%) of ProPts. More lesions (12 pts, 57.1%) were characterized by patchy consolidations, which was described as unusual. But, in 3 patients, cavitary lesion, suspicious for malignancy, was found. Of all patients, 14 were diagnosed by surgical complete removal, and 7 diagnosed by bronchoscopy. In pathologic features, most of cases (20 cases) showed the granuloma. But, necrosis was shown in 9 cases (8 in ProPts and 1 PePts). All patients had been treated by antifungal agent and showed a favorable outcome. CONCLUSIONS: Clinicopathologic features of pulmonary cryptococcosis was variable between ProPts and PePts. Early recognition and pathologic examination may help with improvement of its diagnosis and prognosis. CLINICAL IMPLICATIONS: Pulmonary cryptococcal infection is commonly seen in immunocompromised patients (ProPts), although immunocompetent patients (PePts) may also be infected. but, clinicopathologic features of pulmonary cryptococcosis was variable between ProPts and PePts.
