Background:
To systematically review all cases of orofacial granulomatosis (OFG) and evaluate the association between OFG and Crohn disease (CD).
Summary:
This review was conducted according to PRISMA guidelines and a search of the PubMed, MEDLINE, and Embase databases, and the Cochrane Library in March 2020, using keywords and MeSH terms associated with "orofacial granulomatosis," "Crohn disease," and their variants, with no language restrictions and across all age groups. All relevant articles were accessed in full text. Single case reports and articles on sarcoidosis, allergy, ulcerative colitis, and infectious diseases were excluded from the analysis.
Results:
We retrieved 507 reports on OFG. The mean age at onset was 23.3 years (range 2-89 years). A total of 240 (47.3%) females and 267 (52.6%) males were included. CD was present in 93 children aged <16 years (68.3%) and in 43 adults (31.9%). In most cases, the OFG appeared before the CD. The most common clinical manifestations were intraoral mucosa abnormalities (n = 251; 49.5%), lower-lip swelling (n = 249; 49.1%), upper-lip swelling (n = 227; 44.7%), and gingivae (n = 193; 38.7%). Patients with concurrent CD were more likely to experience involvement of the buccal sulcus. Key Messages: OFG presents primarily as a solo entity. The OFG that was associated with CD was present in 93 children aged under 16 years (68.3%) and in 43 adults (31.9%). Childhood onset of OFG carries with it a higher risk of developing CD.

Inflammatory Bowel Disease II: Crohn's Disease
Inflammatory bowel disease, commonly known as IBD, refers to a collection of disorders that lead to persistent inflammation of the gastrointestinal tract. The two types of IBD are ulcerative colitis, which impacts the colon, and Crohn's disease, which can involve any part of the gastrointestinal segment.

Inflammatory Bowel Disease I: Ulcerative Colitis
Inflammatory bowel disease, or IBD, encompasses a group of disorders characterized by chronic inflammation or ulceration of the gastrointestinal tract.
Risk Factors
The exact cause of IBD remains unclear, although it is believed to be due to a mix of genetic, environmental, microbial, and immune factors. Genetic factors are significant in determining susceptibility to IBD, with family history being a critical risk factor. Individuals with a first-degree relative who has IBD are at...
