Extensive Oral Mucormycosis in a Transplanted Patient.

Mucormycosis is an invasive fungal disease caused by fungi from the Mucorales order that are found in the soil and decaying organic debris. Mucormycosis has been reported to be the third most common fungal disease in stem cell transplanted patients. The fungi have a tendency for vascular invasion, resulting in thrombi development, which decreases blood supply and leads to extensive tissue necrosis. Here, the authors present a patient of mucormycosis affecting the soft palate, oropharynx, and hypopharynx in a type II diabetic male patient who underwent allogeneic stem cell transplantation, and the authors further review the literature on oral mucormycosis for the last 10 years.
