Successful Treatment of Maxillary Mucormycosis: Report of a Case and Literature Review

Opportunistic fungal infections, such as mucormycosis, often occur in immunocompromised patients. Predisposing conditions include metabolic disorders (e.g. uncontrolled diabetes), corticosteroid or immunosuppressive therapy, desferoxamine therapy, burns, solid organ or bone marrow transplants, or neutropenic hematologic malignant diseases and their corresponding treatment. The infection begins in the nose and paranasal sinuses due to inhalation of fungal spores. The infection can spread to orbital and intracranial structures either by direct invasion or through the blood vessels. The fungus invades the arteries leading to thrombosis that subsequently causes necrosis of hard and soft tissues. We report a case of maxillary necrosis by mucormycosis in an uncontrolled diabetic patient and its successful treatment to emphasize that early diagnosis and prompt treatment can reduce the mortality and morbidity of this lethal fungal infection.

Maxillary necrosis by mucormycosis. a case report and literature review

Medicina oral, patología oral y cirugía bucal, 2007

The maxilla rarely undergoes necrosis due to its rich vascularity. Maxillary necrosis can occur due to bacterial infections such as osteomyelitis, viral infections such as herpes zoster or fungal infections such as mucormycosis, aspergillosis etc. Mucormycosis is an opportunistic fulminant fungal infection, which mainly infects immunocompromised patients. The infection begins in the nose and paranasal sinuses due to inhalation of fungal spores. The infection can spread to orbital and intracranial structures either by direct invasion or through the blood vessels. The fungus invades the arteries leading to thrombosis that subsequently causes necrosis of hard and soft tissues. We report a case of maxillary necrosis by mucormycosis in an uncontrolled diabetic patient to emphasize early diagnosis of this potentially fatal fungal infection. We briefly discuss different diseases which can lead to maxillary necrosis and review the current concepts in management of mucormycosis. Early diagno...

Mucormycosis causing maxillary osteomyelitis

Mucormycosis is an opportunistic fungal infection, more commonly observed in immunocompromised patients. The mode of infection is via the inhalation route and infection begins initially in the nose and paranasal sinuses with subsequent invasion into the vascular tissue, eventually leading to thrombosis and necrosis of nearby hard and soft tissues. Here, we report a case of chronic osteomyelitis of the maxillary bone with fungal infection (mucormycosis) and extensive tissue necrosis in an uncontrolled diabetes mellitus patient.

Mucormycosis of maxillary sinus invading maxilla: A case report

International Journal of Medical and Dental Case Reports, 2018

Mucormycosis is a fungal infection caused by saprophytic fungus that can be found in soil, fruits, and decaying vegetables. Mucormycosis is usually noted in immunocompromised individuals, patients on systemic steroid therapy, in patients having malignant hematologic conditions, poorly controlled diabetic patients, and organ transplant patients. In this report, a case of 49-year-old male with well-controlled diabetes who was diagnosed with mucormycosis of the left maxillary sinus invading maxilla is discussed. Systemic antifungal therapy along with debridement followed by the extraction of teeth and removal of necrotic bone was carried out. Complete debridement was achieved with well-healed maxillary sinus and alveolus with no signs of recurrence of the disease.

Maxillary osteomyelitis associated with COVID-19: mucormycosis or not? A series of cases

Brazilian Dental Science, 2024

Aim: A series of cases have been presented involving the oral cavity focusing on the presentation, diagnosis and treatment of mucormycosis that can form a basis for successful therapy. Background: The management of severe coronavirus disease (COVID-19) in conjunction with comorbidities such as diabetes mellitus, hematological malignancies, organ transplants, and immunosuppression have led to a rise of mucormycosis which is an opportunistic infection. Cases Description: The various forms that have been enlisted till date are rhinocerebral, rhino-orbital, gastrointestinal, cutaneous, and disseminated mucormycosis. From the dentistry and maxillofacial surgery perspective, the cases depicting extension of mucormycosis into the oral cavity have been less frequently recorded and thus, require a detailed study. The patients that reported to our private practice had non-tender swelling, draining sinuses and mobility of teeth. A similarity was observed in the clinical signs both in osteomyelitis and mucormycosis. Thus, a histopathological examination was used to establish the definitive diagnosis. Conclusion: Mucormycosis is a life threatening pathology that requires intervention by other branches to make an early diagnosis and commence the treatment. The characteristic ulceration or necrosis is often absent in the initial stage and thus, histopathological examination and radiographic assessment are required to formulate a definitive diagnosis. Early intervention is a necessity to avoid morbidity. The treatment involves surgical debridement of the necrotic infected tissue followed by systemic antifungal therapy. Mucormycosis has recently seen a spike in its prevalence, post the second-wave of coronavirus pandemic in India. It was seen commonly in patients with compromised immunity, diabetes mellitus, hematological malignancies, or on corticosteroid therapy. Mucormycosis invading the palate mostly via maxillary sinus has been less frequently described. In the post-COVID era the features associated with mucormycosis involving oral cavity, should warrant a possible differential diagnosis and managed appropriately.

Mucormycosis: A Case Report and Review of Literature

Journal of Oral Medicine and Pain, 2014

Mucormycosis is a rare but fatal fungal infection with low survival rate in immune-compromised patients. It is caused by a fungus belonging to the Mucoraceae family of the Zygomycetes class. Mucormycosis is classified as rhino-orbital-cerebral, pulmonary, cutaneous, gastrointestinal, disseminated, and miscellaneous types according to its clinical manifestations. Early diagnosis and treatment along with correction of the underlying medical condition is important for favorable results. This case presentation describes mucormycosis involving the anterior maxillary region in a leukemic patient with prolonged neutropenia. The patient benefited from a timely biopsy and immediate treatment with amphotericin B, and was successfully managed with an interdisciplinary team approach consisting of dental and several medical specialists.

Mucormycosis of Mandible with Unfavorable Outcome

Case Reports in Dentistry, 2012

Mucormycosis is a fulminant fungal infection that occurs most often in diabetic and immunocompromised individuals. Our patient, with uncontrolled diabetes mellitus and multiple systemic disorders, developed postextraction mucormycosis of mandible, an extremely rare complication. An initial clinical and radiographic diagnosis of mandibular osteomyelitis was made and the lesion was treated medically and surgically with curettage and saucerisation. The specimen was sent for histopathological evaluation, which showed necrotic area containing broad aseptate fungal hyphae with right angle branching consistent with mucormycosis. The patient succumbed to multipleorgan failure secondary to septicemia. The disease is usually fatal with a poor survival rate; there is still paucity of literature on the definitive management of this disease involving the mandible. This paper emphasizes the need for correction of underlying immunodeficiency and early diagnosis with aggressive multimodality treatm...

Mucormycosis of the jaw after dental extractions: two case reports

Sultan Qaboos University medical journal, 2006

Mucormycosis is a rare opportunistic fungal infection, which is mainly reported to occur in patients with immunocompromised conditions such as uncontrolled diabetes mellitus and leukaemias. In this paper, two cases of mucormycosis are reported after dental extractions. The first case of mucormycosis occurred in the maxilla and mandible of a 14 year old male patient undergoing chemotherapy for acute myeloid leukaemia. The second case occurred in the mandible of a 49 year old male patient with a recently diagnosed type-2 diabetes mellitus, presenting with ketoacidosis and underlying undiagnosed acute lymphoblastic leukaemia. The outcome of these reported cases of mucormycosis was favourable after comprehensive surgical and medical management.

A Case of Successfully Treated Rhinocerebral Mucormycosis: Dental Implications

International Journal of Dentistry, 2010

This paper presents a case of rhinocerebral mucormycosis in a 22-year-old female patient with type I diabetes mellitus, who was successfully treated with surgery and long-term antifungal medication. The patient had initially been submitted to extraction of an upper third molar by a general dental practitioner but was referred to our department three days postoperatively because of double vision. Immediately following histopathological confirmation of the infection, the patient was administered Amphotericin B and Posaconazole intravenously. Surgical excision of the affected site was relatively conservative. The patient was free of the disease 15 months after initial admission to the hospital and has recently returned for reconstruction. The aim of this paper is to increase the awareness of general dental practitioners regarding uncommon serious conditions in diabetic patients, which may be confused with periodontal or dental diseases.
