Mucormycosis is a rare life-threatening opportunistic infection caused by fungi of the order Mucorales. We report a case of rhinocerebral mucormycosis caused by Rhizopus arrhizus var. tonkinensis, the first formally reported case in the literature. Early diagnosis, reversal of predisposing factors, surgical debridement and prompt administration of antifungal therapy are critical for good outcome.

Actinomucor elegans is a fungus belonging to mucormycetes and is still probably underdiagnosed due to misidentification. Based on a recent first case of Actinomucor elegans sinusitis in Europe, in an immunocompromised patient under voriconazole treatment, this paper aims to summarize knowledge about A. elegans mucormycoses. Even if the diagnosis of mucormycosis was made using traditional mycology techniques, precise identification of the fungus could only be achieved using molecular tools. In this observation, the galactomannan dosage was positive until the introduction of treatment and surgical debridement...

Mucormycosis is a fungal infection with fulminant angioinvasion leading to high morbidity and mortality in susceptible individuals. The major predisposing conditions are uncontrolled diabetes, neutropenia, malignancies, receipt of a transplant and traumatic injury [1]. Over the past decade, mucormycosis has become an emerging fungal infection due to the increase in patient groups presenting with these pre-disposing conditions and our medical advances in diagnosing the infection [2-4]. Yet, we currently lack clinical interventions to treat mucormycosis effectively...

The purpose of presenting this case is to report a fatal case of rhinocerebral mucormycosis post-dental extraction in a patient with uncontrolled diabetes mellitus. Several cases of rhinocerebral mucormycosis have been reported, but mucocutaneous mucormycosis has not been commonly reported to be a part of polymicrobial wound infections at multifocal sites. To the best of author's knowledge, this is the second case of polymicrobial rhinocerebral infection involving mucormycosis.

Invasive fungal infections are a major cause of morbidity and mortality, especially for immunocompromised patients. Treatment options are few and most are limited by safety and formulation concerns. Isavuconazole is a new triazole antifungal agent with official indications for the treatment of invasive fungal infections caused by Aspergillus and Mucormycosis. Its clinical efficacy has been proven in two landmark trials, SECURE and VITAL. This review aims to summarize and evaluate the published literature reporting clinical pharmacokinetic and pharmacodynamic outcome data of isavuconazole in humans...

Pulmonary mucormycosis, a relatively rare pulmonary fungal disease, is difficult to diagnose and lacks effective treatment. The present study reports the case of a 64-year-old patient who was treated successfully for pulmonary mucormycosis in Xuan Wu Hospital. The patient presented with low-grade fever and a productive cough that persisted for 1 month with no evident cause, and also suffered from diabetes mellitus. Prior antibiotic treatment with levofloxacin had been ineffective. Culture of mucus obtained by bronchoscopy resulted in a diagnosis of pulmonary mucormycosis...

Two Vietnamese potbellied pigs ( Sus scrofa) had respiratory disease and, on autopsy, both pigs had large masses in the lungs and thoracic cavity. Microscopically, pulmonary and pleural masses contained large areas with hyphae surrounded by hypereosinophilic cellular debris rimmed by abundant eosinophils, lymphocytes, plasma cells, and histiocytes with occasional multinucleate giant cells. The hypereosinophilic debris usually formed tight cuffs, or "sleeves" around the hyphae, compatible with Splendore-Hoeppli-like material...

PURPOSE: The aim of this study was to describe radiological imaging findings of a complicated sinusitis, which should raise the suspicion of rhino-orbital-cerebral mucormycosis as being the underlying cause. METHODS: In this retrospective analysis, we describe the cases and imaging findings of 8 patients with proven mucormycosis. These patients presented mostly with new facial or orbital swelling and were referred for imaging to our institution. Magnetic resonance imaging and computed tomography images were classified as abnormal or normal with respect to orbital, paranasal and cerebral signal results...

Rhinocerebral mucormycosis is an acute, rapidly fatal, fungal infection, classically involving the nasal mucosa and paranasal sinuses. It is an aggressive, opportunistic infection that frequently progresses to involve the orbit and cerebrum. Cerebral extension in immunocompromised patients is almost universally fatal. There are limited data on mucormycosis in pediatric immunocompromised patients in the literature, with only few reports on rhinocerebral involvement. The immunocompromised patients described in this report presented with suspected periorbital and nasal cellulitis, progressing rapidly to necrotic changes in nasal tissue and oral palatal mucosa...

Introduction. Posaconazole is a triazole antifungal that is used in the treatment of a variety of fungal infections, as well as in the management of mucormycosis (on an off-label basis). Eosinophilia associated with exposure to azole antifungals has been described rarely in the literature. Case presentation. A 31-year-old male on peritoneal dialysis (PD) for end-stage renal disease, secondary to diabetic nephropathy, presented to hospital with abdominal pain after a trip to St Lucia. He was taken to the operating room, where the PD catheter was removed and an abdominal-wall abscess was debrided...

Mucormycosis is a life-threatening invasive fungal disease that affects a variety of patient groups. Although Mucorales are mostly opportunistic pathogens originating from soil or decaying vegetation, there are currently few data on prevalence of this group of fungi in the environment. The aim of the present study was to assess the prevalence and diversity of species of Mucorales from soil samples collected in France. Two grams of soil were homogenized in sterile saline and plated on Sabouraud dextrose agar and RPMI agar supplemented with itraconazole or voriconazole...

Background: Solid organ transplant (SOT) recipients are at risk for invasive fungal disease (IFD). Data on IFD burden in pediatric patients are limited. We aimed to determine the incidence and outcome of IFD in a large cohort of pediatric patients who underwent SOT. Methods: A single-center cohort of pediatric patients who underwent SOT between 2000 and 2013 was assembled retrospectively. The patients were followed for 180 days after transplant or until death to determine the presence or absence of IFD...

INTRODUCTION: Early diagnosis of acute invasive fungal rhinosinusitis (AIFR) is crucial for patients prognosis and may reduce the extent of surgical debridement. Initial evaluation usually includes paranasal Computed Tomography (CT), with an emphasis on bony erosion which is considered a specific but insensitive radiologic sign. Most studies made no distinction between Aspergillus and Mucor species while addressing CT findings. In this study, we seek to evaluate whether bony erosion on paranasal CT is a significant and reliable finding in the initial evaluation of invasive paranasal mucormycosis...

A 61-year-old man with relapsing chronic lymphocytic leukaemia, status post allogeneic stem cell transplant and multiple chemotherapy regimens presented to the emergency room after suffering a grand mal seizure. His evaluation revealed a 1.5-2 cm ring-enhancing left temporal lobe brain lesion on the CT scan. This brain lesion was resected and the histopathology revealed an invasive fungal organism resembling mucormycosis. Amplification and sequencing of the 28S ribosomal RNA gene identified the organism as Rhizomucor pusillus The patient was treated with liposomal amphotericin B 5 mg/kg every 24 hours for 4 weeks, and then was transitioned to oral posaconazole...

BACKGROUND AND PURPOSE: Invasive fungal infections cause morbidity and mortality in patients with hematologic malignancies and immunosuppression. Although these infections are commonly caused by Candida and Aspergillus species, infections caused by Mucoralean fungi are also on a growing trend. The definitive diagnosis of mucormycosis includes visualization of non-septate hyphae on pathology or growth of Mucoralean fungi culture. Polymerase chain reaction (PCR) is used to diagnose mucormycosis from paraffin blocks; however, it yields discrepant results in diagnosis of mucormycosis from blood samples...
