Abstract
Mucormycosis, a rare but life-threatening fungal infection, poses significant challenges in clinical management, particularly in patients with uncontrolled diabetes mellitus. This case report presents the clinical journey of a 44-year-old woman who developed a rapidly progressing Mucorales infection following a domestic knife injury. Her condition, complicated by diabetic ketoacidosis and co-infection with Candida albicans, led to severe hand phlegm and sepsis. Despite aggressive intervention, the infection continued to advance, ultimately resulting in the patient's demise.

Abstract
Although mucormycosis may have reached an epidemic situation during the COVID-19 pandemic, the term was much more familiar even before the COVID-19 period. The year 2020 showed an outbreak of novel coronavirus (SARS-CoV-2) which affected millions of people all over the world. One of the noticeable complications observed to be associated with this disease is mucormycosis. It is an opportunistic infection caused by members of the Order Mucorales existing worldwide and has been commonly reported as a laboratory contaminant for a long time. However, nowadays due to the changes in the host environment, they have been emerging as potent opportunistic pathogens responsible for causing primary infections or coinfections with other diseases eventually resulting in morbidity and even mortality in severe cases. Although immunocompromised patients are more susceptible to this infection, few cases have been reported in immunocompetent individuals. Various risk factors which are responsible for the acquisition of mucormycosis include diabetes mellitus type 2, ketoacidosis, hematological malignancies, organ transplants, and chemotherapy recipients. Among the various etiological agents, Rhizopus is found to be the most common, and rhino-cerebral to be the most frequent clinical presentation. As far as pathogenesis is concerned, host cell invasion, thrombosis, and necrosis are the main events in the progression of this disease. The aim of the present review is to address a complete spectrum of mucormycosis and COVID-19-associated mucormycosis (CAM) in a single article. Both global and Indian scenarios of mucormycosis are taken into account while framing this review.

Abstract
Mucormycosis (MCM) is a rare fungal disorder that has recently been increased in parallel with novel COVID-19 infection. MCM with COVID-19 is extremely lethal, particularly in immunocompromised individuals. The collection of available scientific information helps in the management of this co-infection, but still, the main question on COVID-19, whether it is occasional, participatory, concurrent, or coincidental needs to be addressed. Several case reports of these co-infections have been explained as causal associations, but the direct contribution in immunocompromised individuals remains to be explored completely. This review aims to provide an update that serves as a guide for the diagnosis and treatment of MCM patients' co-infection with COVID-19. The initial report has suggested that COVID-19 patients might be susceptible to developing invasive fungal infections by different species, including MCM as a co-infection. In spite of this, co-infection has been explored only in severe cases with common triangles: diabetes, diabetes ketoacidosis, and corticosteroids. Pathogenic mechanisms in the aggressiveness of MCM infection involves the reduction of phagocytic activity, attainable quantities of ferritin attributed with transferrin in diabetic ketoacidosis, and fungal heme oxygenase, which enhances iron absorption for its metabolism. Therefore, severe COVID-19 cases are associated with increased risk factors of invasive fungal co-infections. In addition, COVID-19 infection leads to reduction in cluster of differentiation, especially CD4+ and CD8+ T cell counts, which may be highly implicated in fungal co-infections. Thus, the progress in MCM management is dependent on a different strategy, including reduction or stopping of implicit predisposing factors, early intake of active antifungal drugs at appropriate doses, and complete elimination via surgical debridement of infected tissues.

Abstract
BACKGROUND Mucormycosis has emerged as an increasingly important fungal disease for immunocompromised children and neonates, with the cutaneous form being one of its most common presentations. METHODS We present a cutaneous mucormycosis case in a 10-year-old girl and analyze reports of single cases and case series of cutaneous mucormycosis in ≤16-year-old patients, recorded in PUBMED from 1953 to 2020, for epidemiology, risk factors, diagnostic and therapeutic procedures and outcome. RESULTS 113 cases were enrolled. Median age was 5 years [Interquartile Range (IQR) 10.9], without gender predominance. Underlying conditions were hematologic malignancies/disorders (25.7%), prematurity (23%), solid organ transplantation (3.5%), diabetes mellitus type 1 (4.4%), immunodeficiency and other diseases (14.2%), and no underlying conditions (29.2%). Inoculation occurred through major trauma (12.4%), including surgery and motor vehicle accidents, catheter sites (27.4%), dressings, patches and probes (11.5%), burns and farm-related accidents (8.8%). Rhizopus spp. was most frequently isolated (43.4%), followed by Lichtheimia corymbifera (9.7%), Saksenaea vasiformis (8%), Mucor and Rhizomucor spp. (5.3% each), other species/combinations (7.2%) and unspecified isolates (21.2%). Surgery was combined with antifungals in 62.8%. Each was performed solely in 27.4% and 6.2%, respectively. Amphotericin B was used in 78% (alone in 55.8% and combined with other antifungals in 22.2%) of the cases. Overall mortality was 26.5%. In regression analysis, prematurity and hematologic malignancies/disorders were associated with increased mortality, whereas combination of antifungals and surgery with improved survival. CONCLUSION Cutaneous mucormycosis mainly affects premature infants and children with hematologic malignancies/disorders. Outcome is improved when active antifungal therapy and surgery are combined.

Abstract
INTRODUCTION During Operation Enduring Freedom in Afghanistan, an outbreak of combat-related invasive fungal wound infections (IFIs) emerged among casualties with dismounted blast trauma and became a priority issue for the Military Health System. METHODS In 2011, the Trauma Infectious Disease Outcomes Study (TIDOS) team led the Department of Defense IFI outbreak investigation to describe characteristics of IFIs among combat casualties and provide recommendations related to management of the disease. To support the outbreak investigation, existing IFI definitions and classifications utilized for immunocompromised patients were modified for use in epidemiologic research in a trauma population. Following the conclusion of the outbreak investigation, multiple retrospective analyses using a population of 77 IFI patients (injured during June 2009 to August 2011) were conducted to evaluate IFI epidemiology, wound microbiology, and diagnostics to support refinement of Joint Trauma System (JTS) clinical practice guidelines. Following cessation of combat operations in Afghanistan, the TIDOS database was comprehensively reviewed to identify patients with laboratory evidence of a fungal infection and refine the IFI classification scheme to incorporate timing of laboratory fungal evidence and include categories that denote a high or low level of suspicion for IFI. The refined IFI classification scheme was utilized in a large-scale epidemiologic assessment of casualties injured over a 5.5-year period. RESULTS Among 720 combat casualties admitted to participating hospitals (2009-2014) who had histopathology and/or wound cultures collected, 94 (13%) met criteria for an IFI and 61 (8%) were classified as high suspicion of IFI. Risk factors for development of combat-related IFIs include sustaining a dismounted blast injury, experiencing a traumatic transfemoral amputation, and requiring resuscitation with large-volume (>20 units) blood transfusions. Moreover, TIDOS analyses demonstrated the adverse impact of IFIs on wound healing, particularly with order Mucorales. A polymerase chain reaction (PCR)-based assay to identify filamentous fungi and support earlier IFI diagnosis was also assessed using archived formalin-fixed, paraffin-embedded tissue specimens. Although the PCR-based assay had high specificity (99%), there was low sensitivity (63%); however, sensitivity improved to 83% in tissues collected from sites with angioinvasion. Data obtained from the initial IFI outbreak investigation (37 IFI patients) and subsequent TIDOS analyses (77 IFI patients) supported development and refinement of a JTS clinical practice guideline for the management of IFIs in war wounds. Furthermore, a local clinical practice guideline to screen for early tissue-based evidence of IFIs among blast casualties at the Landstuhl Regional Medical Center was critically evaluated through a TIDOS investigation, providing additional clinical practice support. Through a collaboration with the Uniformed Services University Surgical Critical Care Initiative, findings from TIDOS analyses were used to support development of a clinical decision support tool to facilitate early risk stratification. CONCLUSIONS Combat-related IFIs are a highly morbid complication following severe blast trauma and remain a threat for future modern warfare. Our findings have supported JTS clinical recommendations, refined IFI classification, and confirmed the utility of PCR-based assays as a complement to histopathology and/or culture to promote early diagnosis. Analyses underway or planned will add to the knowledge base of IFI epidemiology, diagnostics, prevention, and management.

Abstract
Mucormycosis is an opportunistic fungal disease that targets individuals having an impaired immune system due to a wide array of risk factors including HIV-AIDS, immunosuppressive therapy, diabetes mellitus, etc. The current explosive outbreak of coronavirus disease 2019 (COVID-19) has become the latest threat to such patients who are already susceptible to secondary infections. Physiological outcomes of COVID-19 end up in a cascade of grave alterations to the immunological profile and irreparable harm to their respiratory passage, heart and kidneys. Corticosteroidal treatment facilitates faster recovery and alleviates the adverse pathological effects of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). But clinical reports lend this approach a darker perspective especially if these patients have pre-existing diabetes mellitus. The mucormycotic fungal genera belonging to the order Mucorales not only survive but thrive under the comorbidity of COVID-19 and diabetes, often staying undetected until they have inflicted irreversible damage. Steroidal usage has been noted to be a common thread in the sudden spurt in secondary fungal infections among COVID-19 cases. Once considered a rare occurrence, mucormycosis has now acquired a notoriously lethal status in mainstream medical hierarchy. We set out to investigate whether corticosteroidal therapy against COVID-19 emboldens the development of mucormycosis. We also assess the conditions brought forth by steroidal usage and uncontrolled progression of diabetes in COVID-19 cases and their effect on the susceptibility towards mucormycosis.

Abstract
BACKGROUND Disseminated mucormycosis presenting with multiple subcutaneous nodules is a rare condition with a poor prognosis, and delayed diagnosis and treatment is common. CASE PRESENTATION We report a case of 64-year-old Thai woman with colorectal cancer who initially presented with Acinetobacter baumannii pneumonia and respiratory failure. Following 10 days after her admission to the intensive care unit, she developed hospital-acquired pneumonia. Five days later, multiple subcutaneous nodules appeared on both arms and both legs. Bronchoalveolar lavage and skin biopsy cultures both grew Mucor spp. She was diagnosed with disseminated mucormycosis and was treated with liposomal amphotericin B at a dose of 5 mg/kg/day. Despite treatment, our patient succumbed to septic shock and multiorgan failure on the third day after definitive diagnosis. CONCLUSIONS This case demonstrates that the subcutaneous nodules caused by hematogenously disseminated mucormycosis are unusual in a patient with a solid tumor. Clinicians should be aware of this atypical presentation of mucormycosis in patients with solid tumors.

Abstract
OBJECTIVES Mucormycosis is a rare angioinvasive infection caused by filamentous fungi with a high lethality among the immunocompromised. In healthy people, the innate immune system is sufficient to prevent infection. The exception to this is deep tissue exposure seen during trauma. The purpose of this study is to evaluate the epidemiology of mucormycosis using a statewide population-based data set. METHODS This is a retrospective cohort study of all hospital admissions for mucormycosis within the state of Florida from 1997 through the beginning of 2020. A distribution map was created to evaluate for geographic variation. Botanical growth zones, based on plant hardiness, used by state environmental agencies and landscapers were also used to detect possible patterns based on climate conditions throughout Florida. A multivariable regression analysis was performed to account for confounders and limit bias. RESULTS A total of 1190 patients were identified for mucormycosis infection. Only 86 of these patients were admitted for trauma. Cutaneous infections were more prevalent among trauma patients while non-trauma patients had more pulmonary infections (P = .04). Trauma patients with infection tended to be younger and less likely to suffer from comorbidities such as immunosuppression (36% vs 46%, P = .07) and diabetes (22.1% vs 47.1%, P ≤ .0001) as compared to their non-trauma counterparts. Mortality was similar with 17.8% for non-trauma patients and 15.1% for traumatized patients (AOR .80 [.42, 1.52]). Length of stay was longer for trauma patients (37.3 vs 23.0, P < .0001). Infections were less prominent in plant hardiness Zone 9 and Zone 10 as compared to Zone 8 (AOR .71 [.61, .82]; AOR .54 [.46, .64], respectively). CONCLUSION Trauma patients who develop infection from mucormycosis are at high risk of death despite being a younger and healthier population. Mucormycosis infections were primarily soft tissue based among trauma patients. These infections are more prevalent in colder regions within Florida.

Abstract
CASE A healthy 21-year-old man underwent an elective gastrocnemius recession for plantar fasciitis. At 10 days postoperatively, he developed a severe limb-threatening cutaneous mucormycotic infection that led to multiple debridements and eventual skin grafting. CONCLUSION Cutaneous mucormycosis is a rare but severe fungal infection. Early recognition, deep surgical biopsy for diagnosis, and aggressive treatment with frequent thorough surgical debridements and antifungal pharmacotherapy are necessary. Although mucormycosis is more frequently seen in the immunocompromised host, it can occur in the immunocompetent patient most commonly after trauma. If not aggressively treated, it can be limb and life threatening.

Abstract
In India, Apophysomyces species complex is the second common agent of mucormycosis mainly affecting immunocompetent hosts unlike other Mucorales. It is frequently involved in causing necrotizing cutaneous infections. The present two-year study was planned to investigate the causative role of Apophysomyces spp. in cutaneous necrotizing infections. The tissue samples were processed using standard techniques and in five out of 65 patients, Apophysomyces variabilis was the etiological agent. Diabetes mellitus and trauma were common risk factors and despite appropriate treatment only one patient could be survived. Apophysomyces variabilis is emerging as agent of necrotizing infections which invariably result in poor patient outcomes.

Abstract
Mucormycosis is a deadly infection which is caused by fungi of the order Mucorales including species belonging to the genus Rhizopus, Mucor, Mycocladus, Rhizomucor, Cunninghamella, and Apophysomyces. Despite antifungal therapy and surgical procedures, the mortality rate of this disease is about 90-100% which is exceptionally high. The hypersensitivity of patients with raised available serum iron indicates that the Mucorales are able to use host iron as a critical factor of virulence. This is because iron happens to be a crucial element playing its role in the growth of cells and development. In this review, we have described Lactoferrin (Lf) as a potential iron-chelator. Lf is a naturally occurring glycoprotein which is expressed in most of the biological fluids. Moreover, Lf possesses exclusive anti-inflammatory effects along with several anti-fungal effects that could prove to be helpful to the pathological physiology of inexorable mucormycosis cases. This literature summarises the biological insights into the Lf being considered as a potential fungistatic agent and an immune regulator. The review also proposes that unique potential of Lf as an iron-chelator can be exploited as the adjunct treatment for mucormycosis infection.

Abstract
Mucormycosis is a rare but aggressive fungal disease that mainly affects patients with poorly controlled diabetes mellitus and those who are severely immunocompromised, including patients with hematological malignancies and solid organ transplant recipients. Early recognition of infection is critical for treatment success, followed by prompt initiation of antifungal therapy with lipid formulation amphotericin B. Posaconazole and isavuconazole should be used for stepdown and salvage therapy. Surgical debridement is key for tissue diagnosis and treatment and should be pursued urgently whenever possible. In addition to surgery and antifungal therapy, reverting the underlying risk factor for infection is important for treatment response.

Abstract
Superficial mycoses of skin, nails and hair are among the common fungal infections. They are caused by dermatophytes, non-dermatophyte moulds, yeasts and yeast-like fungi. Such fungal infections are widespread all over the world and are predominant in tropical as well as subtropical regions. Environmental factors, such as warm, humid and pitiable hygienic conditions, are conducive for their growth and proliferation. Although it does not cause mortality, it is known to be associated with excessive morbidity which may be psychological or physical. This affects the quality of life of the infected individuals which leads to a negative impact on their occupational, emotional and social status. Such infections are increasing on a global scale and, therefore, are of serious concern worldwide. This review article covers the global and Indian scenario of superficial mycoses taking into account the historical background, aetiological agents, prevalence, cultural and environmental factors, risk factors, pathogenesis and hygienic practices for the prevention of superficial mycoses.

Abstract
BACKGROUND The body of evidence on cutaneous mucormycosis is largely derived from case reports or single-centre databases. OBJECTIVES Our study aimed to describe incidence, predisposing factors and inpatient outcomes of cutaneous mucormycosis in the United States. METHODS We conducted a population-based retrospective study using the National Inpatient Sample 2016-17 data. Fifty-six discharges had a diagnosis of cutaneous mucormycosis on the International Classification of Diseases, tenth revision. Descriptive analysis was performed for the demographics, predisposing factors, length of stay (LOS), cost and inpatient mortality. The NIS represents 20% of all discharges in the United States, which allowed us to estimate the national incidence of cutaneous mucormycosis. RESULTS An estimated total of 280 admissions occurred between 2016 and 2017, indicating 3.9 cases per million admissions across the United States. The estimated incidence rate was 0.43 cases per million people per year. Median age was 49.5 (19-59) years, 44.6% were female, and 54.9% were Caucasian. We identified haematologic malignancies (48.2%) and solid organ transplantations (10.7%), often accompanied by skin/soft tissue or post-procedural infections, were the most common predisposing conditions. Median LOS was 15 (6-31) days, median total charges were 187,030 (65,962-446,265) USD, and in-hospital mortality rate was 16.1%. CONCLUSIONS In current clinical practice, physicians may encounter cutaneous mucormycosis most commonly in severely immunocompromised hosts with haematologic malignancies or transplantations, accompanied by skin/soft tissue or post-procedural infections. A high index of suspicion and prompt tissue sampling in at-risk groups is important to improve the outcomes.

Abstract
Mucormycosis are a group of infections that affect principally immunocompromised host and have a high mortality. Liposomal amphotericin B is the first-line treatment with combined surgical removal of the infectious focus. We report the case of 67-year-old man with idiopathic granulocytic aplasia and a cutaneous lesion caused by Rhizopus arrhizus treated with isavuconazole. Its safety profile and spectrum of activity make it an important therapeutic option.

Abstract
Gradations in skin color are a consequence of differing amounts of melanin and their varying distribution. Although many darkly pigmented skin lesions are melanocytic and can be attributed to melanin content, the color of a black lesion can also be due to blood, necrotic tissue, or exogenous pigment. The source, pattern, and distribution of the color in black lesions usually offer important insight into its etiology. This contribution reviews conditions that can take on a black color, discussing the cause of the hue and any additional impact sun exposure may have.

Abstract
Patients with extensive burns are an important group at risk for cutaneous mucormycosis. This study aimed to perform a systematic review of all reported mucormycosis cases in burn patients from 1990 onward. A Medline search yielded identification of 7 case series, 3 outbreaks, and 25 individual cases reports. The prevalence reached 0.04%–0.6%. The median age was 42–48 in the case series and outbreaks, except for the studies from military centers (23.5–32.5) and in individual reports (29.5). The median total body surface area reached 42.5%–65%. Various skin lesions were described, none being pathognomonic: the diagnosis was mainly reached because of extensive necrotic lesions sometimes associated with sepsis. Most patients were treated with systemic amphotericin B or liposomal amphotericin B, and all underwent debridement and/or amputation. Mortality reached 33%–100% in the case series, 29%–62% during outbreaks, and 40% in individual cases. Most patients were diagnosed using histopathology and/or culture. Mucorales qPCR showed detection of circulating DNA 2–24 days before the standard diagnosis. Species included the main clinically relevant mucorales (i.e., Mucor, Rhizopus, Absidia/Lichtheimia, Rhizomucor) but also more uncommon mucorales such as Saksenaea or Apophysomyces. Contact with soil was reported in most individual cases. Bandages were identified as the source of contamination in two nosocomial outbreaks.

Abstract
Mucormycosis is an angio-invasive fungal infection, associated with high morbidity and mortality. A change in the epidemiology of mucormycosis has been observed in recent years with the rise in incidence, new causative agents and susceptible population. The rise has been perceived globally, but it is very high in the Asian continent. Though diabetes mellitus overshadow all other risk factors in Asia, post-tuberculosis and chronic renal failure have emerged as new risk groups. The rhino-cerebral form of mucormycosis is most commonly seen in patients with diabetes mellitus, whereas, pulmonary mucormycosis in patients with haematological malignancy and transplant recipients. In immunocompetent hosts, cutaneous mucormycosis is commonly seen following trauma. The intriguing clinical entity, isolated renal mucormycosis in immunocompetent patients is only reported from China and India. A new clinical entity, indolent mucormycosis in nasal sinuses, is recently recognized. The causative agents of mucormycosis vary across different geographic locations. Though Rhizopusarrhizus is the most common agent isolated worldwide, Apophysomycesvariabilis is predominant in Asia and Lichtheimia species in Europe. The new causative agents, Rhizopus homothallicus, Mucor irregularis, and Thamnostylum lucknowense are reported from Asia. In conclusion, with the change in epidemiology of mucormycosis country-wise studies are warranted to estimate disease burden in different risk groups, analyse the clinical disease pattern and identify the new etiological agents.

Abstract
Mucormycosis is an emerging life-threatening fungal infection caused by Mucorales. This infection occurs mainly in immunocompromised patients, especially with hematological malignancy, transplantation, or diabetes mellitus. Rhino-orbito-cerebral and pulmonary mucormycosis are the predominant forms. Interestingly, location is associated with the underlying disease as pulmonary mucormycosis is more frequent in hematological malignancy patients whereas rhino-orbito-cerebral mucormycosis is associated with diabetes. Cutaneous mucormycosis results from direct inoculation, mainly after trauma or surgery. Gastro-intestinal mucormycosis occurs after ingestion of contaminated food or with contaminated device and involves the stomach or colon. Disseminated disease is the most severe form and is associated with profound immunosuppression. Uncommon presentations with endocarditis, osteoarticluar or isolated cerebral infections are also described. Finally, health-care associated mucormycosis is a matter of concern in premature newborns and burn units. Clinical symptoms and CT scan findings are not specific, only the early reversed halo sign is associated with pulmonary mucormycosis. Circulating Mucorales DNA detection is a recent promising diagnostic tool that may lead to improving the diagnosis and prompting therapeutic initiation that should include antifungal treatment, correction of the underlying disease and surgery when feasible.

Abstract
BACKGROUND Accurate diagnosis of mucormycosis, a life-threatening fungal infection, remains a challenge for physicians. OBJECTIVES To identify the causative Mucorales in fresh clinical samples and formalin-fixed paraffin-embedded (FFPE) samples of patients with proven mucormycosis by molecular method. PATIENTS/METHODS Fresh clinical samples of patients with proven mucormycosis according to the EORTC/MSG criteria admitted between 2015 and 2017 and histopathologically proven FFPE archives collected during 2004-2007 and 2015-2017 from Mazandaran University-affiliated hospitals of northern Iran were included. Seminested PCR targeting the 18S rDNA of Mucorales and ITS region was performed, and PCR products were then sequenced. RESULTS While culture was positive only in 5 of 9 (56%) of fresh specimen cases, PCR was positive in all 9 (100%) histologically proven mucormycosis. Ten of 18 (56%) FFPE samples were PCR-positive. Overall, Mucorales PCR was positive in 19 of 27 (70%) samples. Mucorales species were Rhizopus arrhizus in 16 (84%) cases, R. arrhizus/Amylomyces rouxii in 2 (10.5%) cases and Rhizopus stolonifer in one case (5.5%). Among 27 mucormycosis cases, 25 (93%) cases were rhinocerebral, and 2 (7%) cases were disseminated. Diabetes mellitus (74%) and neutropaenia (63%) were the main risk factors. CONCLUSIONS Seminested PCR targeting 18S rDNA region of Mucorales is useful for identification of the causative agents of mucormycosis.

Abstract
Cutaneous mucormycosis is an emerging fungal infection caused by opportunistic
fungi of the phylum Glomeromycota. It is frequent in poorly controlled diabetic
patients and individuals with immunosuppression. It is usually acquired by
direct inoculation through trauma. The clinical presentation is nonspecific, but
an indurated plaque that rapidly evolves to necrosis is a common finding.
Diagnosis should be confirmed by demonstration of the etiological agent and new
molecular diagnostic tools have recently been described. It is an invasive
life-threatening disease and in order to improve survival, a prompt diagnosis
and multidisciplinary management should be provided. The treatment of choice is
amphotericin B, but new azoles, such as posaconazole and isavuconazole, must be
considered.

Abstract
PURPOSE OF REVIEW Skin and soft tissue infections are frequent contributors to morbidity and mortality in the immunocompromised host. This article reviews the changing epidemiology and clinical manifestations of the most common cutaneous pathogens in non-HIV immunocompromised hosts, including patients with solid organ transplants, stem cell transplants, solid tumors, hematologic malignancies, and receiving chronic immunosuppressive therapy for inflammatory disorders. RECENT FINDINGS Defects in the innate or adaptive immune response can predispose the immunocompromised host to certain cutaneous infections in a predictive fashion. Cutaneous lesions in patients with neutrophil defects are commonly due to bacteria, Candida, or invasive molds. Skin lesions in patients with cellular or humoral immunodeficiencies can be due to encapsulated bacteria, Nocardia, mycobacteria, endemic fungal infections, herpesviruses, or parasites. Skin lesions may reflect primary inoculation or, more commonly, disseminated infection. Tissue samples for microscopy, culture, and histopathology are critical to making an accurate diagnosis given the nonspecific and heterogeneous appearance of these skin lesions due to a blunted immune response. SUMMARY As the population of non-HIV immunosuppressed hosts expands with advances in medical therapies, the frequency and variety of cutaneous diseases in these hosts will increase.

Abstract
Mucormycosis is an aggressive fungal infection caused by zygomycetes from the order of Mucorales. Immunocompromised patients or patients with comorbidities are susceptible to this infection. There are many forms of mucormycosis such as rhino-orbito-cerebral, cutaneous, gastrointestinal, and pulmonary. Cutaneous mucormycosis is rare in trauma patients with no comorbidities. Morel-Lavallée lesions are rare degloving injuries in trauma patients. We report a case of cutaneous mucormycosis in a trauma patient with the Morel-Lavallée lesions.

Abstract
Invasive fungal infection (IFI) is a rare but serious complication of traumatic injury. The purpose of this article is to review the epidemiology, natural history, mycology, risk factors, diagnosis, treatment, and outcomes associated with post-traumatic IFI in military and civilian populations. The epidemiology of post-traumatic IFI is poorly characterized, but incidence appears to be rising. Patients often suffer from severe injuries and require extensive medical interventions. Fungi belonging to the order Mucorales are responsible for most post-traumatic IFI in both civilian and military populations. Risk factors differ between these cohorts but include specific injury patterns and comorbidities. Diagnosis of post-traumatic IFI typically follows positive laboratory results in the appropriate clinical context. The gold standard of treatment is surgical debridement in addition to systemic antifungal therapy. Patients with post-traumatic IFI may be at greater risk of amputation, delays in wound healing, hospital complications, and death as compared to trauma patients who do not develop IFI. More research is needed to understand the factors surrounding the development and management of post-traumatic IFI to reduce the significant morbidity and mortality associated with this disease.

Abstract
Basidiobolomycosis is an uncommon cutaneous zygomycete infection typically seen in immunocompetent individuals. Diagnosis can be made by biopsy and fungal culture of the lesion. Treatment with Potassium iodide and co-trimoxazole is simple and effective. Early and accurate diagnosis of basidiobolomycosis is essential to avoid dissemination and mortality. We present a case with basidiobolomycosis resembling Fournier's gangrene.

Abstract
BACKGROUND Opportunistic fungal infections caused by Aspergillus and Candida followed by infections with Fusarium, Rhizopus, Mucor, and Alternaria species are an important cause of morbidity and mortality in patients with hematological malignancies. Cutaneous mucormycosis infections are rare, and the incidence, outcomes, and factors associated with survival in the setting of hematological malignancies are not clear. METHODS A literature search was conducted for all cases of primary cutaneous mold infections in patients with hematological malignancy, of which 50 cases were found. Our case of a patient with a hematological malignancy who sustained a cat bite that in turn caused a primary cutaneous mold infection is also included. RESULTS In the 51 cases identified, 66.7% were neutropenic upon presentation, and 54.9% were male with an average age of 32 years. Aspergillus species (33.3%) was the most cited followed by Rhizopus species (19.6%). Overall mortality rate was 29.4% and was observed more frequently in patients with neutropenia (60.0%) and without surgical intervention (73.3%). Survival rate was higher (35.3%) for cases utilizing both antifungal and surgical intervention. The antifungal agent with the highest survival rate was amphotericin B and its formulations (58.8%). CONCLUSIONS Neutropenia within hematological malignancies demonstrate a risk for developing severe cutaneous fungal infections, of which primary cutaneous mucormycosis can carry significant mortality. Combination antifungal therapy and surgical debridement appears to be associated with higher survival outcomes and warrants further investigation.

Abstract
OBJECTIVE Clinicians have anecdotally noted that combat-related invasive fungal wound infections (IFIs) lead to residual limb shortening, additional days and operative procedures before initial wound closure, and high early complication rates. We evaluated the validity of these observations and identified risk factors that may impact time to initial wound closure. DESIGN Retrospective review and case-control analysis. SETTING Military hospitals. PATIENTS/PARTICIPANTS US military personnel injured during combat operations (2009-2011). The IFI cases were identified based on the presence of recurrent, necrotic extremity wounds with mold growth in culture, and/or histopathologic fungal evidence. Non-IFI controls were matched on injury pattern and severity. In a supplemental matching analysis, non-IFI controls were also matched by blood volume transfused within 24 hours of injury. INTERVENTION None. MAIN OUTCOME MEASUREMENTS Amputation revision rate and loss of functional levels. RESULTS Seventy-one IFI cases (112 fungal-infected extremity wounds) were identified and matched to 160 control patients (315 non-IFI extremity wounds). The IFI wounds resulted in significantly more changes in amputation level (P < 0.001). Additionally, significantly (P < 0.001) higher number of operative procedures and longer duration to initial wound closure were associated with IFI. A shorter duration to initial wound closure was significantly associated with wounds lacking IFIs (Hazard ratio: 1.53; 95% confidence interval, 1.17-2.01). The supplemental matching analysis found similar results. CONCLUSIONS Our analysis indicates that IFIs adversely impact wound healing and patient recovery, requiring more frequent proximal amputation revisions and leading to higher early complication rates. LEVEL OF EVIDENCE Prognostic Level III. See Instructions for Authors for a complete description of levels of evidence.

Abstract
Combat trauma wounds with invasive fungal infections (IFIs) are often polymicrobial with fungal and bacterial growth, but the impact of the wound microbiology on clinical outcomes is uncertain. Our objectives were to compare the microbiological features between IFI and non-IFI wounds and evaluate whether clinical outcomes differed among IFI wounds based upon mold type. Data from U.S. military personnel injured in Afghanistan with IFI wounds were examined. Controls were matched by the pattern/severity of injury, including blood transfusion requirements. Wound closure timing was compared between IFI and non-IFI control wounds (with/without bacterial infections). IFI wound closure was also assessed according to mold species isolation. Eighty-two IFI wounds and 136 non-IFI wounds (63 with skin and soft tissue infections [SSTIs] and 73 without) were examined. The time to wound closure was longer for the IFI wounds (median, 16 days) than for the non-IFI controls with/without SSTIs (medians, 12 and 9 days, respectively; P < 0.001). The growth of multidrug-resistant Gram-negative rods was reported among 35% and 41% of the IFI and non-IFI wounds with SSTIs, respectively. Among the IFI wounds, times to wound closure were significantly longer for wounds with Mucorales growth than for wounds with non-Mucorales growth (median, 17 days versus 13 days; P < 0.01). When wounds with Mucorales and Aspergillus spp. growth were compared, there was no significant difference in wound closure timing. Trauma wounds with SSTIs were often polymicrobial, yet the presence of invasive molds (predominant types: order Mucorales, Aspergillus spp., and Fusarium spp.) significantly prolonged the time to wound closure. Overall, the times to wound closure were longest for the IFI wounds with Mucorales growth.

Abstract
This article reviews four immunocompetent patients who developed a rare fungal infection, mucormycosis, secondary to multiple traumatic injuries sustained during an EF-5 tornado in Joplin, MO. Commonly found in soil and decaying organic matter, mucorales are fungi associated with soft tissue and cutaneous infections. Onset of this fungal infection can occur without clinical signs, presenting several days to several weeks after injury, delaying diagnosis. A multidisciplinary treatment approach including aggressive antifungal therapy and aggressive surgical debridement is critical. This diagnosis should be considered in all patients presenting with injuries sustained from high-velocity embedment of debris such as natural disasters or explosions. We present four cases of mucormycosis, species Apophysomyces trapeziformis. Data reported includes predisposing factors, number of days between injury and diagnosis of mucormycosis, surgical treatment, antifungal therapy, outcomes, and potential risk factors that may have contributed to the development of mucormycosis.

Abstract
BACKGROUND The mucoralean fungi are emerging causative agents of primary cutaneous infections presenting in the form of necrotizing fasciitis. AIMS The aim of this study was to investigate a series of suspected necrotizing fasciitis cases by Apophysomyces species over one-year period in a northern Indian hospital. METHODS The clinical details of those patients suspected to suffer from fungal necrotizing fasciitis were recorded. Skin biopsies from local wounds were microscopically examined and fungal culturing was carried out on standard media. The histopathology was evaluated using conventional methods and special stains. Apophysomyces isolates were identified by their morphology and by molecular sequencing of the internal transcribed spacer (ITS) region of the ribosomal genes. Antifungal susceptibility testing was carried out following EUCAST guidelines and treatment progress was monitored. RESULTS Seven patients were found to be suffering from necrotizing fasciitis caused by Apophysomyces spp. Six isolates were identified as Apophysomyces variabilis and one as Apophysomyces elegans. Five patients had previously received intramuscular injections in the affected area. Three patients recovered, two died and the other two left treatment against medical advice and are presumed to have died due to their terminal illnesses. Posaconazole and terbinafine were found to be the most active compounds against A. variabilis, while the isolate of A. elegans was resistant to all antifungals tested. CONCLUSIONS Apophysomyces is confirmed as an aggressive fungus able to cause fatal infections. All clinicians, microbiologists and pathologists need to be aware of these emerging mycoses as well as of the risks involved in medical practices, which may provoke serious fungal infections such as those produced by Apophysomyces.

Abstract
Cutaneous disease is the third most frequent manifestation of mucormycosis. The clinical manifestations of and subsequent mortality due to cutaneous mucormycosis are dependent on the mode of acquisition and the host immune status. Here, we describe the epidemiology, clinical presentation, microbiology, and outcomes of 16 cutaneous mucormycosis infections managed in an Australian tertiary hospital over a 15-year period. The proportion with localized (56%), deep (38%), and disseminated (6%) cutaneous disease as well as the overall mortality (25%) were consistent with findings reported in the published literature. Two novel forms of hospital-acquired infection were reported following a sacral pressure sore and insertion of a foreign body during a bone graft procedure. The majority of patients were immunocompetent (75%) and/or suffered trauma (56%) with associated environmental contamination. A novel finding was that motor vehicle accidents (MVAs) accounted for 78% of all trauma-related cases, suggesting MVAs should receive greater recognition as a potential precipitant of cutaneous mucormycosis. Aggressive decontamination and debridement of devitalized tissue following trauma is therefore likely to play an important role in the prevention of this rare but potentially devastating infection.

Abstract
Combat-related invasive fungal (mold) wound infections (IFIs) have emerged as an important and morbid complication following explosive blast injuries among military personnel. Similar to trauma-associated IFI cases among civilian populations, as in agricultural accidents and natural disasters, these infections occur in the setting of penetrating wounds contaminated by environmental debris. Specific risk factors for combat-related IFI include dismounted (patrolling on foot) blast injuries occurring mostly in southern Afghanistan, resulting in above knee amputations requiring resuscitation with large-volume blood transfusions. Diagnosis of IFI is based upon early identification of a recurrently necrotic wound following serial debridement and tissue-based histopathology examination with special stains to detect invasive disease. Fungal culture of affected tissue also provides supportive information. Aggressive surgical debridement of affected tissue is the primary therapy. Empiric antifungal therapy should be considered when there is a strong suspicion for IFI. Both liposomal amphotericin B and voriconazole should be considered initially for treatment since many of the cases involve not only Mucorales species but also Aspergillus or Fusarium spp., with narrowing of regimen based upon clinical mycology findings.

Abstract
Mucormycoses are life-threatening infections with fungi from the order Mucorales (Mucoromycotina). Although mucormycoses are uncommon compared to other fungal infections, e.g. aspergillosis and candidiasis, the number of cases is increasing especially in immunocompromised patients. Lichtheimia (formerly Absidia) species represent the second to third most common cause of mucormycoses in Europe. This mini review presents current knowledge about taxonomy and clinical relevance of Lichtheimia species. In addition, clinical presentation and risk factors will be discussed. Proper animal infection models are essential for the understanding of the pathogenesis and the identification of virulence factors of fungal pathogens. To date, several animal models have been used to study Lichtheimia infection. A brief overview of the different models and the main conclusions from the infection experiments is summarised in this review.

Abstract
BACKGROUND Deep cutaneous fungal infections (DCFIs) are responsible for significant morbidity and mortality, particularly in immunocompromised patients. Although a direct correlation between histopathologic examination and culture is expected, discordant findings may be seen, presenting a unique diagnostic and therapeutic challenge. OBJECTIVES We sought to determine the correlation between skin tissue cultures and histopathologic examination in patients with DCFI. METHODS This is a 10-year retrospective review (2003-2012) of patients with a diagnosis of DCFI seen at a single tertiary care institution. Tissue cultures and histopathologic findings were reviewed. RESULTS In 8 of 33 cases, fungal elements were seen on routine histopathologic sections but skin cultures were negative. Three of 8 of the discordant cases had concurrent positive non-skin tissue cultures that correlated with the pathology interpretation, and 3 of 8 patients in the discordant group died of systemic fungal infection. LIMITATIONS This was a retrospective study design and a single tertiary care institution experience. CONCLUSIONS The histopathologic interpretation of skin tissue specimens is critical for rapid and accurate diagnosis of DCFI. Despite the identification of fungal organisms on histopathologic assessment of skin tissue specimens, skin tissue culture may fail to show fungal growth. A diagnosis of a DCFI and initiation of appropriate treatment should always be considered in spite of discordant results.

Abstract
BACKGROUND An outbreak of invasive fungal infections (IFI) began in 2009 among United States servicemen who sustained blast injuries in Afghanistan. In response, the military trauma community sought a uniform approach to early diagnosis and treatment. Toward this goal, a local clinical practice guideline (CPG) was implemented at Landstuhl Regional Medical Center (LRMC) in early 2011 to screen for IFI in high-risk patients using tissue histopathology and fungal cultures. METHODS We compared IFI cases identified after initiation of the CPG (February through August 2011) to cases from a pre-CPG period (June 2009 through January 2011). RESULTS Sixty-one patients were screened in the CPG period, among whom 30 IFI cases were identified and compared with 44 pre-CPG IFI cases. Demographics between the two study periods were similar, although significantly higher transfusion requirements (p<0.05) and non-significant trends in injury severity scores and early lower extremity amputation rates suggested more severe injuries in CPG-period cases. Pre-CPG IFI cases were more likely to be associated with angioinvasion on histopathology than CPG IFI cases (48% versus 17%; p<0.001). Time to IFI diagnosis (three versus nine days) and to initiation of antifungal therapy (seven versus 14 days) were significantly decreased in the CPG period (p<0.001). Additionally, more IFI patients received antifungal agent at LRMC during the CPG period (30%) versus pre-CPG period (5%; p=0.005). The CPG IFI cases were also prescribed more commonly dual antifungal therapy (73% versus 36%; p=0.002). There was no statistical difference in length of stay or mortality between pre-CPG and CPG IFI cases; although a non-significant reduction in crude mortality from 11.4% to 6.7% was observed. CONCLUSIONS Angioinvasive IFI as a percentage of total IFI cases decreased during the CPG period. Earlier diagnosis and commencement of more timely treatment was achieved. Despite these improvements, no difference in clinical outcomes was observed compared with the pre-CPG period.
