[Pulmonary pneumocystosis in an adult patient]

A 34-year-old male with no diseases in the past developed, after a 7-day alcoholic abuse, an acute pancreatitis and ulcerative necrotic colitis. At the autopsy, apart from the underlying disease, the pulmonary pneumocystosis was found which is considered by the authors as a complication of a severe pathology of the alimentary tract organs followed by immune system dysfunction.
