Microscopic colitis is a noninfectiouscolitis that is characterizedby chronic nonbloodydiarrhea and macroscopicallynormal colonic mucosa. Extraintestinalmanifestationsare rarely seen. In this report,we describe a nonspecific interstitialpneumonitis in a patientwith lymphocytic colitis.

Blastoschizomyces capitatus is an emerging pathogen that causes infection primarily in patients who have immune system dysfunction. The author reports a case of pulmonary blastoschizomycosis in an immunocompetent man who was successfully treated with voriconazole.

The authors report a case of idiopathic eosinophilic pneumonia in a man with sclerosing cholangitis and ulcerative colitis associated with features of sarcoidosis.

Allopurinol, commonly used to treat patients with gout, has been known to cause hypersensitivity reactions. We report a case of drug-induced delayed multiorgan hypersensitivity syndrome secondary to allopurinol use. To the best of our knowledge, this is the first reported case of diffuse alveolar hemorrhage in a patient presenting with allopurinol-induced rash with eosinophilia and systemic symptoms.
