Abstract
We report a case of Candida glabrata endophthalmitis which was effectively treated by intravitreal liposomal amphotericin B (L-AMB) injection. A 72-year-old man was referred to our department for positive blood culture of Candida glabrata. First ophthalmologic examination revealed a chorioretinal lesion in left eye, and the patient was diagnosed as possible candida chorioretinitis. Despite systemic antifungal therapy, his chorioretinal lesion increased in both eyes and complicated by vitritis. Intravitreal administration of L-AMB was introduced for probable candida endophthalmitis. Finally, improvement of vitritis and regression of chorioretinal lesions were obtained by total of 9 times intravitreal injection. Our case suggests the safety and efficacy of intravitreal L-AMB injection for Candida glabrata endophthalmitis.

Abstract
Liposomal amphotericin B is a lipid formulation of the antifungal drug amphotericin B with some distinguishing characteristics in its pharmacological behavior that entail some clinical differences of great interest. The significant improvement in the systemic and renal tolerability is one of them. This fact is related to the great stability of the liposome, promoted by its negative charge, the presence of cholesterol and the remarkable thermo-stability of the remaining lipids that compose it. In this situation, amphotericin B seems to be released from the liposome not spontaneously but when the liposome binds to the ergosterol in the fungal cell membrane. For this reason, there is almost no free amphotericin B in plasma or tissues, although it seems that its availability is greater when there is fungal infection. As a consequence, when the pharmacokinetic behavior is studied, the concentration and availability of liposomal amphotericin B are very high, and its volume of distribution is reduced in comparison with the other formulations.

Abstract
PURPOSE To determine the intraocular penetration of amphotericin B (AMPH-B) after an intravenously injection of liposomal amphotericin B (L-AMB) in inflamed human eyes. METHODS Seven eyes of 5 patients with fungal eye diseases (endophthalmitis in 6 eyes and keratitis in 1 eye) were treated with intravenous injections of 100-250 mg/day of L-AMB. Samples of blood, corneal button, aqueous humor, and vitreous humor were collected and assessed for AMPH-B. RESULTS The AMPH-B level in the cornea (604.0 μg/g) of the case with fungal keratitis exceeded the minimum inhibitory concentration. However, the levels in the aqueous and vitreous humors of the cases with fungal endophthalmitis were lower, e.g., 0.02 ± 0.01 μg/ml (0.09% of serum level) in the aqueous humor and 0.05 ± 0.08 μg/ml (0.17% of serum level) in the vitreous humor. CONCLUSIONS The AMPH-B levels administered intravenously were very low in the aqueous and vitreous humors. Our findings indicate that intravenous L-AMB can be considered only for patients with mild endogenous fungal endophthalmitis, e.g., isolated chorioretinitis without vitreous extensions.

Abstract
BACKGROUND Post kala-azar dermal leishmaniasis (PKDL) is thought to be the reservoir of infection for visceral leishmaniasis in South Asia. The development of strategies for the diagnosis and treatment of PKDL are important for the implementation of the visceral leishmaniasis elimination program. AIMS Liposomal amphotericin B (L-AMB) has been an overwhelming success in the treatment of visceral leishmaniasis. However, the empirical three-week regimen of L-AMB proposed for PKDL was shown to be inadequate, especially in the macular variant. This study aimed to delineate response of the different variants of PKDL to L-AMB. METHODS Skin biopsies were collected from PKDL cases at disease presentation and upon completion of treatment with L-AMB. Parasite DNA was detected by Internal Transcribed Spacer-1 PCR (ITS-1 PCR) and quantified by amplification of parasite kDNA. CD68 + macrophages were estimated in tissue sections by immunohistochemistry. RESULTS Treatment with L-AMB decreased the parasite load by 97% in polymorphic cases but only by 45% in macular cases. The median parasite load (89965 vs 5445 parasites/μg of genomic DNA) as well as infiltration by CD68+ cells before treatment was much greater in the polymorphic cases. LIMITATIONS Although monitoring of the parasite load for 12 months post-treatment would have been ideal, this was not possible owing to logistical issues as well as the invasive nature of biopsy collection procedure. CONCLUSION A dramatic decrease in the parasite burden was noted in patients with polymorphic lesions. Although patients with macular disease also had a decrease in parasite burden, this was not as marked as in the polymorphic cases. There was also a significantly greater infiltration of CD68 + macrophages in polymorphic PKDL before therapy.

Abstract
Paracoccidioidomycosis (PCM) is a systemic granulomatous fungal infection rarely associated with solid organ transplantation. We report the second case of PCM in an adult after liver transplantation. A 47-year-old woman who had undergone liver transplantation was hospitalized for flu-like symptoms and multiple erythematous ulcerated skin papules. There was lymphadenopathy, pulmonary compromise, and quickly progression to septic shock. PCM was confirmed by skin biopsy and serologic tests, and a satisfactory response to amphotericin B was achieved.

Abstract
Invasive trichosporonosis is a rare and lethal fungal infection that occurs in immunocompromised patients. Breakthrough trichosporonosis can occur in patients treated with echinocandins since Trichosporon spp. are resistant to these antifungal agents. We report a case of breakthrough Trichosporon asahii fungemia. A 62-year-old Japanese woman with relapsed follicular lymphoma was treated empirically with broad-spectrum antibiotics and micafungin due to an intermittent fever during reinduction chemotherapy. After four cycles of anti-cancer chemotherapy, she experienced a high neutropenic fever and T. asahii was subsequently detected from a blood culture. The patient was not given voriconazole due to the contraindication for use with carbamazepine, and she was successfully treated with fluconazole plus liposomal amphotericin B without any serious complications. The combined therapy of fluconazole and liposomal amphotericin B may therefore be useful in treating T. asahii fungemia, especially in patients receiving antiepileptic agents.

Abstract
Invasive aspergillosis is a significant cause of mortality in patients with hematological malignancy. Early diagnosis of invasive pulmonary aspergillosis (IPA) by bronchoscopy is recommended but is often difficult to perform because of small lesion size and bleeding risk due to thrombocytopenia. A 71-year-old woman had received initial induction therapy for acute myeloid leukemia. On day 22 of chemotherapy, she had a high fever, and the chest computed tomography scan revealed a 20-mm-sized nodule with a halo sign. Bronchoscopy assisted by virtual bronchoscopic navigation (VBN) and endobronchial ultrasonography with a guide sheath (EBUS-GS) was performed, and Aspergillus terreus was identified from the culture of obtained specimens. A. terreus is often resistant to amphotericin B; thus, voriconazole is usually recommended for treatment. However, the obtained A. terreus isolate showed minimal inhibitory concentrations of 2 µg/mL for voriconazole and 0.5 µg/mL for amphotericin B. Therefore, the patient was successfully treated with liposomal amphotericin B. For patients suspected of having IPA, early diagnosis and drug susceptibility testing are very important. This case suggests that bronchoscopy using VBN and EBUS-GS is helpful for accurate diagnosis and successful treatment even if the lesion is small and the patient has a bleeding risk.

Abstract
Amphotericin B (AmB) is a polyene antifungal agent used widely for systemic fungal infections. Infusion-related side effects, nephrotoxicity, and dyselectrolytemia are well-known adverse effects with the use of this drug. Liposomal preparation of AmB has less adverse events. However, ototoxicity due to AmB is scarcely mentioned in the literature. We report a case of disseminated histoplasmosis who was treated with liposomal amphotericin B (LAmB) and developed hearing loss during the treatment, which recovered after discontinuing the drug. This is a rare adverse effect of LAmB and reported only once from India, to the best of our knowledge.

Abstract
Background Liposomal amphotericin B (L-AMB), a broad-spectrum antifungicidal drug, is often used to treat fungal infections. However, clinical evidence of its use in patients with renal dysfunction, especially those receiving renal replacement therapy (RRT), is limited. Therefore, we evaluated the usage and occurrence of adverse reactions during L-AMB therapy in patients undergoing RRT. Methods Using claims data and laboratory data, we retrospectively evaluated patients who were administered L-AMB. The presence of comorbidities, mortality rate, treatment with L-AMB and other anti-infective agents, and the incidence of adverse reactions were compared between patients receiving RRT, including continuous renal replacement therapy (CRRT) and maintenance hemodialysis (HD), and those that did not receive RRT. Results In total, 900 cases met the eligibility criteria: 24, 19, and 842 cases in the maintenance HD, CRRT, and non-RRT groups, respectively. Of the patients administered L-AMB, mortality at discharge was higher for those undergoing either CRRT (15/19; 79%) or maintenance HD (16/24; 67%) than for those not receiving RRT (353/842; 42%). After propensity score matching, the average daily and cumulative dose, treatment duration, and dosing interval for L-AMB were not significantly different between patients receiving and not receiving RRT. L-AMB was used as the first-line antifungal agent for patients undergoing CRRT in most cases (12/19; 63%). Although the number of subjects was limited, the incidence of adverse events did not markedly differ among the groups. Conclusion L-AMB may be used for patients undergoing maintenance HD or CRRT without any dosing, duration, or interval adjustments.

Abstract
INTRODUCTION Invasive fungal diseases are crucial causes of morbidity and mortality among patients with febrile neutropenia (FN). Though liposomal amphotericin B (L-AMB) is one of the agents recommended for first-line empirical antifungal therapy in patients with FN, large-scale clinical studies have not been performed in Japan. METHODS An open-label prospective multi-center study was carried out to evaluate the safety and efficacy of L-AMB in Japanese patients with FN suspected of having fungal infection. RESULTS Of the 426 patients registered, safety and efficacy evaluations were conducted for 424 and 399, respectively. By clinical response criteria using 5 composite endpoints, the response rate was 46.6% (186/399). The response rate by age were 54.5% (child: 30/55), 47.5% (adult: 97/204), 42.1% (elderly: 59/140) respectively. Regarding the composite endpoints, resolution of fever was observed in 61.2% (244/399), no breakthrough fungal infection in 99.0% (395/399), survival for 7 days or longer after the completion of treatment in 83.7% (334/399), no discontinuation of treatment due to toxicity or lack of efficacy in 60.9% (243/399), and successful treatment of any baseline fungal infection in 10/18. Adverse drug reactions (ADRs) developed in 61.1% (259/424), and frequent ADRs were hypokalemia, kidney dysfunction, and liver dysfunction, as previously reported. CONCLUSIONS The safety and efficacy profile of L-AMB in Japanese patients with FN suspected of having fungal infection were elucidated for the first time, through the analysis of a large number of cases including pediatric patients under real-world clinical settings collected in this nationwide study.

Abstract
We report the case of a 56-year-old Caucasian male affected by thymoma and myasthenia gravis that developed recurrent visceral leishmaniasis 11 years after thymectomy. After treatment of each relapse with liposomal amphotericin B the PCR-Leishmania was negative and the patient showed clinical improvement. An immunologic work-up was performed showing lymphopenia with an important decrease in CD4+ T cells (52 cells/μ) and CD4/CD8 ratio (0.2). HIV test was negative. On the basis of previous thymoma and myasthenia gravis and on the basis of the immunological profile a diagnosis of Good's syndrome was made. Since IFNγ plays a main role in the control of Leishmania infection the production of IFNγ was evaluated. After mitogen stimulation of peripheral blood mononuclear cells the production of IFNγ was lower than normal. This is the second reported case of Good's syndrome with recurrent leishmaniasis and indicates that a definitive cure for leishmaniasis in patients with Good's syndrome is not possible. Immunologic work-up in our patient strongly suggests that relapses could be correlated with the low CD4+ T cell number and with the low IFNγ production. Immunotherapy with IFNγ or with compounds able to block the Th2 interleukin production could be a therapeutic option in these patients.

Abstract
Aspergillus spp. cholangitis is an uncommon presentation of invasive aspergillosis. Only few cases are described in the literature affecting severely immunocompromised patients or patients following biliary surgery. Especially, invasive aspergillosis in non-haematological patients is associated with high mortality rates, caused by atypical presentations, which is associated with a delay in diagnosis and therapy. We report a 72-year-old man with primary diagnosis of cholangiocarcinoma and stent implantation by endoscopic retrograde cholangiopancreatography (ERCP) for biliary decompression who developed severe cholangitis with invasive aspergillosis. The patient had no history of prior hospitalisation, no immunosuppressive therapy and no preceding biliary surgery. Furthermore, in this exceptional case of extrapulmonary aspergillosis, there were no signs of pulmonary involvement. From the literature review, only three cases of Aspergillus cholangitis could be identified. Clinical manifestations of invasive aspergillosis can be variable and classical risk factors such as immunosuppression are not mandatorily present. Clinical awareness of these rare cases is of vital importance for initiation of correct therapy.

Abstract
Leishmaniasis is prevalent in Southern Europe, the Middle East, India, Africa, and Central and South America. Cutaneous leishmaniasis may spontaneously heal over time without treatment; however, risk of visceral dissemination and the impact of cosmetic defect are important concerns. We report a Case of cutaneous leishmaniasis in a patient who ever traveled to Mexico before the onset of a deteriorating wound around the swollen left eyebrow. A diagnosis of infection with Leishmania mexicana was made based on histopathological examination and molecular identification. Systemic treatment with liposomal amphotericin B and ketoconazole were administered with gradual healing of the lesion. Also, this traveler case implicates that the spread of endemic parasitic diseases may be a concealed risk on the public health for Taiwan underlying globalization.

Abstract
Background Mucormycosis is an uncommon fungal infection caused by the members of the order Mucorales. In susceptible patients, mucormycosis can infect any tissue or organ, and without suitable treatment (i.e., debridement and antifungal therapy), this infection can be fatal. Our patient was a woman with lymphoma and cerebral mucormycosis who was treated with antifungals and without any neurosurgical debridement. Case Presentation Herein, we present the case of a 35-year-old woman with diagnosis of B-cell lymphoma and rhino-orbito-cerebral mucormycosis (ROCM). She was a candidate for enucleation of the left eye, orbital decompression, and sinocerebral debridement. Nevertheless, the patient refused eye enucleation and craniotomy. Finally, she was treated with a combination of antifungals and sinus debridement without eye enucleation and craniotomy. Conclusion debridement, along with a combination of liposomal amphotericin B (LAMB) and posaconazole, may be a suitable therapeutic option for patients with ROCM, who are not eligible candidates for extensive surgery or craniotomy.

Abstract
Mucormycosis isolated to the mandible is a rare presentation occurring generally after dental procedures. The case we report presented with discharging sinuses over facial region with radiological appearance of isolated osteomyelitis of the mandible. The patient used to apply an addictive dental powder over his teeth leading to caries. Following this, he pulled out all his teeth, which probably led to his condition. Invasive sampling revealed mucormycosis. An extensive search for an underlying immunodeficiency revealed that the patient had chronic granulomatous disease (CGD). Despite a prolonged course of L-Amphotericin B, the patient continued to have intermittent pus discharge and surgical debridement and curettage was eventually required. The patient had a chronic course with minimal soft tissue involvement which initially did not raise the suspicion of mucormycosis. The main learning point is that an unusual invasive fungal infection in an otherwise healthy host can be the first symptom of an underlying primary immunodeficiency, like CGD. Invasive fungal infections in patients with CGD often have an indolent course. Mucormycosis isolated to the mandible is a rare presentation, occurring generally after dental procedures. Self-extraction of teeth as in our patient can result in isolated mucormycosis of the mandible. Isolated mucormycosis of the mandible can be a presenting symptom of chronic granulomatous disease. Combination of medical and surgical treatment is usually needed in mandibular mucormycosis.

Abstract
IMPORTANCE Pulmonary mucormycosis is life threatening and carries a poor prognosis. Identification of factors that improve prognosis is urgently necessary. OBJECTIVE To analyze the clinical features and outcomes of pulmonary mucormycosis in children. METHODS A retrospective analysis of clinical data of four cases with pulmonary mucormycosis was conducted in Beijing Children's Hospital from January 2017 to December 2018. RESULTS Underlying diseases were identified in all four cases (diabetes in three individuals and a hematological malignancy in one individual). The predominant clinical manifestations were fever, cough, chest pain and hemoptysis. Imaging features included consolidation or nodules with cavities. All four cases were treated with liposomal amphotericin B, one case underwent lobectomy, and three cases received a full course of posaconazole. All four cases were cured. INTERPRETATION Patients with pulmonary mucormycosis often have underlying diseases. Imaging features are relatively characteristic. Treatment with liposomal amphotericin B at an early stage and a sufficient course of posaconazole for maintenance significantly improves prognosis.

Abstract
A diagnosis of rhino-orbital-cerebral mucormycosis was made in a 59-year-old man with a secondary acute myeloid leukemia a few days after hematopoietic stem cell transplantation. Prompt treatment with combined antifungal therapy (liposomal amphotericin B and isavuconazole) followed by a procedure of endoscopic sinus surgery resulted in the resolution of the infection. Therapeutic drug monitoring of isavuconazole was performed during the year of treatment showing an increment of plasma concentrations in correspondence with the improvement of intestinal GvHD, thus suggesting that in this or similar conditions TDM for isavuconazole can be of value. A literature review of cases of rhino-orbital-cerebral and rhino-cerebral mucormycosis in allogeneic hematopoietic stem cell transplant recipients was carried out.

Effect of serum concentration and concomitant drugs on vancomycin-induced acute kidney injury in haematologic patients: a single-centre retrospective study. Eur J Clin Pharmacol 2019; 75:1695-1704. [PMID: 31511938 DOI: 10.1007/s00228-019-02756-4] [Citation(s) in RCA: 10] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/12/2019] [Accepted: 09/01/2019] [Indexed: 12/28/2022]
Abstract
PURPOSE Appropriate use of vancomycin (VCM) is important in preventing acute kidney injury (AKI). Because of the high frequency of VCM use for febrile neutropenia and concomitant use of other nephrotoxic drugs, haematologic patients have a different nephrotoxic background compared with patients with other diseases. Therefore, it is unclear whether the risk factors of VCM-induced AKI identified in other patient groups are also applicable to haematologic patients. Herein, we performed a single-centre retrospective analysis to identify the factors associated with VCM-induced AKI in haematologic patients. METHODS We retrospectively analysed 150 haematologic patients to whom VCM was administered between April 2010 and March 2018 at Tokushima University Hospital. VCM-induced AKI was defined according to Kidney Disease Improving Global Outcomes (KDIGO) criteria. Multivariate logistic regression analyses were performed to identify risk factors for VCM-induced AKI. RESULTS Seventeen patients had VCM-induced AKI. Multivariate analysis revealed that the risk factors of VCM-induced AKI were an initial VCM trough concentration of > 15 mg/L and concomitant use of tazobactam/piperacillin (TAZ/PIPC) and liposomal amphotericin B (L-AMB). Patients with an initial VCM trough concentration of < 10 mg/L showed significantly lower efficacy in febrile neutropenia. Interestingly, concomitant L-AMB use increased the incidence of VCM-induced AKI in a VCM concentration-dependent manner, whereas concomitant TAZ/PIPC increased the incidence in a VCM concentration-independent manner. CONCLUSIONS The optimal initial VCM trough concentration was 10-15 mg/L in haematologic patients, considering safety and effectiveness. There were differences in the effect of VCM-induced AKI between nephrotoxic drugs.

Cutaneous leishmaniasis in non-endemic countries: An emerging yet neglected problem. IDCases 2019; 17:e00570. [PMID: 31275804 PMCID: PMC6587016 DOI: 10.1016/j.idcr.2019.e00570] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/05/2019] [Revised: 05/29/2019] [Accepted: 05/29/2019] [Indexed: 11/21/2022] Open
Abstract
Cutaneous leishmaniasis (CL) is the most common leishmaniasis syndrome, yet a neglected disease in industrialized non-endemic countries, where it has become an emergent problem. The lack of clinical experience, evidence-based literature and availability of some treatments complicates its management. We report a CL case in a 30 year-old man returned from Brazil, with a cutaneous ulcerated lesion, where it was possible to isolate Leishmania braziliensis/guyanensis complex (subgenus Viannia). An initial course of treatment with miltefosine was attempted, but considering the lack of response, liposomal amphotericin B was used, with very good results. Our report highlights the obstacles faced in the diagnosis and treatment of New World CL in non-endemic countries and the need for more funding and research.

Case of endobronchial metastasis from breast cancer accompanied with Cunninghamella bertholletiae tracheobronchial mycetoma. J Infect Chemother 2019; 25:1065-1069. [PMID: 31227382 DOI: 10.1016/j.jiac.2019.05.031] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/26/2019] [Revised: 05/09/2019] [Accepted: 05/27/2019] [Indexed: 11/19/2022]
Abstract
Cunninghamella is a member of the class Zygomycetes. Cunninghamella species include ubiquitous filamentous fungi; infections caused by Cunninghamella species are less frequent but have higher mortality rates than infections caused by Mucorales group members such as Rhizopus and Mucor. Herein, we reported a rare fatal case of endobronchial metastasis from breast cancer accompanied with Cunninghamella bertholletiae tracheobronchial mycetoma. A 73-year-old female with a history of right-sided breast cancer who had undergone mastectomy 11 years previously and had no recurrence presented to our emergency department with a 1-week history of left-sided back pain. Chest X-ray revealed left lung atelectasis; bronchoscopy revealed an endobronchial mass lesion in the left main bronchus. Pathological examination revealed fungal mycetoma but malignant lesions were not detected. Endobronchial and lung mycetoma caused by Cunninghamella bertholletiae were initially diagnosed; liposomal amphotericin B was administered, but her condition deteriorated. Rigid endoscopy showed growth of hemorrhagic tissue occupying the left main bronchus just under the carina. Pathological examination of the shaved lesion revealed metastasis from breast cancer covered with abundant necrotic tissue. No mold was observed in the necrotic tissue; this was probably due to liposomal amphotericin B treatment. To our knowledge, this is the first case of endobronchial metastasis from breast cancer accompanied with Cunninghamella bertholletiae mycetoma. Distinguishing endobronchial metastases from breast cancer and atypical presentations of Cunninghamella endobronchial mycetomas can be very difficult. Repeated bronchoscopies maybe helpful in establishing an accurate diagnosis when clinical prognosis does not match the initial diagnosis.

Abstract
The introduction of the prophylactic use of antifungal drugs caused the increased occurrence of invasive fungal infections due to previously rare molds, such as fusariosis, after allogeneic hematopoietic stem cell transplantation. We herein report the case of a patient with diffuse large B-cell lymphoma who developed fungemia due to Fusarium solani during liposormal amphotericin B on day 25 after cord blood transplantation (CBT). Because Fusarium species might differ in virulence and drug susceptibility, the sequencing of the internal transcribed spacer region of the ribosomal RNA gene accurately identified Fusarium solani to be the cause of fungemia at the species level. This case highlights Fusarium solani as the cause of fungemia in a patient under liposormal amphotericin B treatment after CBT.

Abstract
We report on an elderly male patient with headache and right-side weakness. Imaging studies revealed multiple space-occupying lesions in the parietal and occipital cerebral regions. Biopsy revealed broad aseptate ribbon-like structures branching at right angles, suggestive of mucormycosis. Improvement was observed after medical therapy with 20 weeks of liposomal amphotericin B (5 mg/kg/day) combined with posaconazole, followed by posaconazole (400 mg twice a day) alone for 1 month. The patient recovered without neurological deficits; however, multidrug-resistant bacteraemia and hospital-acquired pneumonia occurred, resulting in death. Nevertheless, our report shows that this lethal fungal infection can sometimes show favourable progress with drug therapy alone.

Abstract
PURPOSE The incidence of Acute invasive fungal rhinosinusitis (AIFRS) is on the rise considering the multitude of comorbidities present in a single patient.The delay in suspecting the fungal etiology, presentation of the patient for an Otorhinolaryngology consult and lack of defined protocols affects outcome.This study looks in to the various aspects of treatment of AIFRS including sample collection, diagnosis and medicosurgical treatment. We propose a protocol for the management of these patients crafted from our outcome. METHODS Between September 2015-September 2017, 14 patients presented with AIFRS. Targeted samples were taken for Potassium hydroxide mount, histopathological studies and fungal culture. Management was initiated with antifungals and multi-approach surgical debridement. RESULTS Six of these patients had multiple comorbidities and most were uncontrolled diabetics. The average delay in presentation was 9 days. Potassium hydroxide mount was the screening test of choice. A minimum of two sittings of debridement was essential. In an average follow-up period of 15.12 months, all the patients are alive and disease free. CONCLUSION A high index of suspicion, awareness among medical fraternity and precise sample collection aids a firm diagnosis. Simultaneous initiation of surgical debridement and anti-fungals is fundamental.

Abstract
A 47-year-old man with acute myeloid leukemia and myelodysplastic-related changes relapsed after an allogenic bone marrow transplant and received a cord blood transplant as salvage therapy. The patient developed febrile neutropenia that was resistant to broad-spectrum antibiotics and multiple, painful, nodular skin lesions on his trunk and extremities before engraftment. A skin biopsy and blood culture found mold, and the subsequent microscopic examination, mass spectrometry, and DNA sequencing of the fungal colonies identified Fusarium solani. The patient's fever and skin lesions began to improve with the administration of liposomal amphotericin B at 5 mg/kg/day. Neutrophilic engraftment occurred on day 19. Stage 3 acute skin graft-versus-host disease was cured by the application of topical steroid. Unexpectedly, a change from liposomal amphotericin B to voriconazole on day 38 exacerbated the Fusarium infection. The Fusarium infection was finally cured by the administration of liposomal amphotericin B for a total of 19 weeks. Neutrophilic engraftment, an immediate definitive diagnosis, the sufficient and long-term administration of appropriate antifungal medication, and avoidance of the systemic administration of steroids might have contributed to the successful outcome of this patient.

Abstract
Gastrointestinal basidiobolomycosis (GIB), a rare fungal infection associated with high mortality, has been reported worldwide mainly from tropical and subtropical regions of Asia, USA, and Latin America. The clinical manifestations are highly diverse and non-specific depending on the underlying disease, but fever, abdominal pain, weight loss, diarrhea, constipation and chills have been observed. There are no prominent risk factors for GIB but climatic conditions and life style are related to this infection in arid and semi-arid regions. Therefore timely diagnosis and early treatment is a challenge. Herein, we present an unusual case of gastrointestinal basidiobolomycosis in a 54-year-old male, initially misdiagnosed as colon cancer. After follow-up, no evidence of relapse and the patient was successfully cured by liposomal amphotericin B. In addition, the differential diagnosis and histopathological findings are discussed with a review of the literature.
