Here we describe a 13-year-old adolescent female diagnosed with concurrent autoimmune disorders including Grave disease, Celiac disease, and autoimmune hepatitis within 3 months after infection with severe acute respiratory syndrome coronavirus 2. The patient initially presented to her pediatrician with complaints of epistaxis, cessation of menses, palpitations, and weight loss. Initial evaluation showed evidence of hyperthyroidism, elevated liver enzymes, and abnormal Celiac disease serologies. Additional testing including laboratory tests, liver biopsy, and an upper endoscopy with biopsies confirmed the diagnosis of Grave disease, Celiac disease, and type 1 autoimmune hepatitis. This case highlights the importance of recognizing the risk of autoimmune disorders associated with the novel coronavirus disease 2019.

Special AT-rich sequence-binding protein 2 (SATB2) is a sensitive and specific biomarker for sporadic colonic adenocarcinomas. Previous studies have found that SATB2 is lost in some adenocarcinomas and dysplasias associated with inflammatory bowel disease (IBD). In establishing these findings, the prior studies did not examine cases of IBD interpreted as indefinite for dysplasia. We examined SATB2 expression in this diagnostic category to determine if any potential loss is associated with a diagnosis of definitive dysplasia on follow-up. To investigate this possibility, we collected 87 biopsies of IBD indefinite for dysplasia from 62 patients and stained them with SATB2. Among patients' indefinite for dysplasia, we found SATB2 loss in 6/62 (9.7%). Among those with follow-up (n=51), we observed 5/6 (83%) with a future dysplasia in those with SATB2 loss compared with 10/45 (22%) in those with SATB2 retention, absolute difference 61.1% (95% confidence interval=28.9%-93.3%). We conclude that loss of SATB2 on biopsies otherwise interpreted as IBD indefinite for dysplasia may mark a population at high risk for showing definitive dysplasia on future biopsies.

ABSTRACT We describe a 9-year-old girl who presented with abdominal pain, found incidentally to have multiple liver granulomata. Extensive autoimmune and infectious workup was negative. The patient had esophagogastroduodenoscopy and colonoscopy, confirming the diagnosis of Crohn's disease. Hepatic granulomata are a rare complication of Crohn's disease and are often secondary to pharmacotherapy or infection in immunosuppressed patients. This case, to our knowledge, is the first reported case of a pediatric patient diagnosed with Crohn's disease after initially presenting with hepatic granulomata as an extraintestinal manifestation of the disease.
