A case report published in English can potentially be indexed in the Science Citation Index (SCI), but it depends on several factors such as the quality of the research, the journal's impact factor, and the relevance of the topic to the field. Case reports are generally considered lower-level research contributions compared to original research articles, experimental studies, or systematic reviews. However, if the case report is well-written, provides new insights, and is published in a reputable journal, it may still have the potential to be included in the SCI database.
