We describe a patient with jaundice who demonstrated granulomas on liver biopsy in response to dapsone. Her symptoms were only evident once steroids, used to also treat her pyoderma gangrenosum, had been tapered. Case Presentation In this case, a 67-year-old female was hospitalized due to 1 day of jaundice. She had started dapsone and prednisone concurrently 7 weeks ago to treat her pyoderma gangrenosum. Steroids were discontinued 4 days prior to symptoms. Her laboratories were notable for newly elevated alkaline phosphatase (756 U/L), aspartate transaminase (199 U/L), alanine transaminase (273 U/L), and total bilirubin (12.6 mg/dL). Dapsone was held due to suspicion for DILI. A liver biopsy was performed and disclosed non-necrotizing hepatic granulomas. After infectious and autoimmune causes were excluded, dapsone was determined to be the cause of her hepatic granulomas. Her bilirubin and liver enzymes steadily normalized over the next 4 weeks following discontinuation of dapsone. Conclusion Thus, dapsone-related liver injury may present following a steroid taper if dapsone and steroids had been initially started together.

GGT is detected incidentally during esophagogastroduodenoscopy (EGD) in a proportion of patients. Endoscopic ultrasound (EUS) evaluation of GGT is essential to establish the diagnosis and to differentiate it from gastrointestinal stromal tumors or gastric neuroendocrine tumors. An 80-year-old man who presented for abdominal discomfort was incidentally found to have a gastric antral nodule on EGD. Endoscopic biopsy demonstrated moderately erythematous gastric antral mucosa and a 1.5 cm subepithelial lesion along the greater curvature. An EUS revealed a subepithelial 1.6 cm × 1.3 cm isoechoic, homogenous lesion with small calcifications. Immunohistochemical staining of the fine needle biopsy specimen of the nodule was positive for neoplastic cells, smooth muscle actin, vimentin, patchy muscle-specific actin, and synaptophysin. There were no atypical cytologic features. These findings were consistent with GGT. The patient was not deemed to be a candidate for surgical resection due to advanced age and resolution of his symptoms. A shared decision was made to pursue regular surveillance. EUS is essential for evaluation of GGT. Currently, there are no guideline recommendations for surveillance of GGT detected on routine EGD in asymptomatic individuals. A definitive surgical treatment with partial gastrectomy was favored in previously published literature. For asymptomatic patients with GGT or those with resolution of symptoms, careful surveillance with serial abdominal imaging and EUS may be a reasonable option, especially in older patients with poor surgical candidacy.","PeriodicalId":9614,"journal":{"name":"Case Reports in Gastroenterology","volume":"24 22","pages":"356 - 361"},"PeriodicalIF":0.6,"publicationDate":"2023-12-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138589507","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
