The authors also reviewed historic articles to gather information about the initial discovery and descriptions of this condition. Results. The authors identified more than 50 articles on the topic. Generally, there was concordance regarding the diagnosis of this condition; however, some questions and controversy exist regarding the pathogenesis and treatment modality of choice. The authors relied on the most representative and complete articles for this review article. Clinical Implications.
