It develops from scarring reaction secondary to ulcerative injury during long‐term NSAID use. The histological features of the diaphragm‐like stricture include fibrosis in the submucosa and thickening of the muscularis mucosa. 4 Since the muscularis propria layer is intact, the risk of intestinal perforation is low with endoscopic balloon dilation, which is why it is a preferred treatment modality than surgical intervention. 5 However, diaphragm‐like strictures tend to be multiple, and resection and/or strictureplasty of the involved intestinal segment may be required.

“A 46-year-old woman presented with a 3-month history of malaise and weight loss (20 kg). These symptoms were accompanied by epigastric pain and watery diarrhea in the last 2 weeks before she was admitted. Her past medical history was significant for chronic kidney disease of unknown etiology for which she had received a cadaveric kidney transplant six years earlier. Immunosuppression consisted of tacrolimus, mycophenolate mophetil and prednisone. She had never traveled outside Portugal. Physical examination
was unremarkable. Laboratory tests revealed an elevated C reactive protein (7.3 mg/dL) and found no evidence of HIV, HBV, HCV, CMV, EBV and Leishmania infections. The patient was submitted in a single session to an upper digestive endoscopy and colonoscopy. In the duodenum, ileum and colon, there were multiple ulcers with raised borders which were biopsied (Figure 1 and Figure 2). Pathology evaluation revealed intense acute old inflammatory infiltrate and numerous intra- and extra-cellular microorganisms identified as Histoplasma spp ( Fig. 3). The patient was started on liposomal amphotericin B, but there was rapid clinical deterioration and she died from multiple organ failure. Histoplasmosis is caused by the fungus H. capsulatum which is found in soil contaminated with bird and bat droppings and is endemic in Southeast Asia, India, Africa and America. Healthy people exposed to H. capsulatum are generally asymptomatic but they may develop acute pulmonary histoplasmosis, a “flu-like” illness. 1 Disseminated histoplasmosis is a severe form of infection which mostly occurs in immunosuppressed individuals and frequently involves the gastrointestinal tract, although often asymptomatically. 2 and 3 Endoscopic lesions include ulcerations and polypoid masses, most often involving the colon or ileum.
