The purpose of our study is to review the literature for studies reporting the dosage of oral corticosteroids as part of the appropriate medical management prior to, immediately before, and after surgical intervention. We reviewed the literature for oral corticosteroid regimens given to patients with CRS from March 2012 to September 2018. Studies that did not disclose the exact doses of the regimen were excluded from our analysis. Our search resulted in 7 articles with 4 studies of Level of Evidence (LOE) 1b, 2 studies with LOE III, and 1 study with LOE IV. The daily doses varied from 15 mg to 1 mg/kg, and with total doses ranging from 150 to 352 mg. In addition, several studies gave the same regimen to both subtypes of CRS. There was no mention of side effects in most of the studies. There is a wide variation in the steroid doses given to patients with CRS and prospective or randomized controlled trials are needed to provide better improved evidence.

Clinical presentation is diverse, considering only less than 100 cases have been reported. However, we report a unique case of isolated collagenous gastritis in a 71-year-old female who presented with a 6-month history of dyspepsia and 27 kg weight loss. Her endoscopic findings revealed a tubular shaped stomach with diffuse gastric mucosal atrophy, findings that differ with previous case reports of a cobblestone pattern. Treatment remains unclear.We report the case of a 42-year-old woman who was diagnosed with breast cancer that recurred 3 years later, wit
