American Journal of Case Reports is ranked the World leading among journals dedicated to publishing clinical case reports. AJCR is indexed in Web of Science, PubMed/ PMC, Scopus

(1) CiteScore (Impact Factor - like by Scopus, Elsevier) is the number of citations received by a journal in one year to documents published in the three previous years, divided by the number of documents indexed in Scopus published in those same three years.

(2) SNIP (Source Normalized Impact per Paper) measures a source’s contextual citation impact by weighting citations based on the total number of citations in a subject field. It helps you make a direct comparison of sources in different subject fields. SNIP takes into account the characteristics of the source's subject field, which is the set of documents citing that source.

(3) SJR is weighted by the prestige of a journal. Subject field, quality, and reputation of the journal have a direct effect on the value of a citation. SJR assigns relative scores to all of the sources in a citation network. Its methodology is inspired by the Google PageRank algorithm, in that not all citations are equal. A source transfers its own 'prestige', or status, to another source through the act of citing it. A citation from a source with a relatively high SJR is worth more than a citation from a source with a lower SJR.

Clinical case reports are an invaluable first-hand source of evidence in medicine and a tool most often used in practice to exchange information and generate a more expanded search for evidence. In addition to the “evidence of what happened”, single or multiple cases are an important basis for further and more advanced research on diagnosis, treatment effectiveness, causes and outcomes of disease. However limited their conclusions may be, case reports remain a fundamental component of medicine, contributing greatly to the advancement of health care. In today's ever-expanding Evidence-Based Medicine, case reporting require a well-defined focus, content, and structure.

Presently, only a fraction of case reports is useful for clinical decision-making and bedside-decision oriented research. Therefore, the aim of the Journal is to gather case reports across medical disciplines, thereby integrating interdisciplinary, international medical knowledge.

BACKGROUND: Fibroepithelial polyps are benign lesions of mesodermal origin, which have been reported in the head and neck area. The aim of this study is to describe the management of an oropharyngeal fibroepithelial polyp causing stridor.
CASE REPORT: A 39-year-old male presented with 24 hours of stridor and dysphagia. Flexible laryngoscopy revealed a pedunculated sessile polyp on the posterior oropharynx. The mass was excised using bipolar diathermy and histopathology revealed a fibroepithelial polyp. The differential diagnoses for stridor are extensive. Although uncommon, a fibroepithelial polyp should be considered.
CONCLUSIONS: We present a rare case of a fibroepithelial polyp causing stridor and imminent airway obstruction. We recommend the use of SponTaneous Respiration using IntraVEnous anaesthesia and High-flow nasal oxygen (STRIVE Hi) for general anaesthesia and resection of pharyngeal polyps.
