Gracin's Syndrome, a Rare Clinical Challenge in the Setting of Invasive Mucormycosis: A Systematic Review.

Garcin's Syndrome is a rare pathology involving multiple cranial nerves in the setting of invasive mucormycosis, usually in immunocompromised patients. Owing to its extremely high mortality rate, clinician should have a high suspicion for diagnosis. This article presents a rare case of Rhino-Orbito-Cerebral Mucormycosis with Garcin's syndrome in a 33-years old male along with a discussion of previously reported cases. The case is discussed in light of scant contemporary literature on the cited subject. A thorough search using the keywords Garcin's Syndrome, Invasive Mucormycosis, Rhino-orbital, Rhino-cerebral mucormycosis, was conducted on Pubmed/MEDLINE, Google scholar, LILACS, medRxiv and Google. A total of six reported cases found in international literature published between 2000 and 2020 were reviewed and analyzed. Garcin's Syndrome is associated with a high mortality rate. In our review, of the total seven patients, only three survived, bringing the collective mortality to 42.85%. Patients had multiple cranial nerve involvement leading to long term sequelae. Our case showed the unique finding of VIII nerve involvement. Early intervention helped in patient survival and better functional outcome. This literature review highlights the distinct clinical nature of the presentation of disease and the importance of prompt diagnosis and early management in the reversal of complications in an otherwise potentially fatal disease.
