Although Saccharomyces boulardii is usually a non-pathogenic fungus, in rare occasions it can cause invasive infection in children. We present the case of an 8-year-old patient in pediatric surgical intensive care unit who developed S. cerevisiae fungemia following probiotic treatment containing S. boulardii. Caspofungin was not effective in this case and he was treated with amphotericin B. We want to emphasize that physicians should be careful about probiotic usage in critically ill patients.

Phaeohyphomycosis is a rare but emerging disease caused by dematiaceous fungi. Here we describe the case of an immunosuppressed dog with disseminated phaeohyphomycosis secondary to Bipolaris spicifera infection. Regionally extensive infiltration of the paw pads, skin, myocardium, liver, renal interstitium and diaphragm was identified on histopathology. Candida glabrata and Fusarium oxysporum were also cultured from multiple sites post-mortem. The dog was treated with fluconazole, itraconazole, terbinafine and liposomal amphotericin B, but was euthanized due to its poor prognosis after 12 days of therapy...

Yeasts are common etiologic agents of onychomycosis. This study reported a case of onychomycosis due to Cryptococcus friedmannii (Naganishia friedmannii). This yeast was isolated of the right great toenail of 57-year-old man. Microscopic examination of nail scrapings showed budding cells with thin capsule. Sequence analyzes of the internal transcribed spacer regions was closely related to Cryptococcus friedmannii. The results of susceptibility testing showed the Cryptococcus friedmannii to be sensitive to fluconazole, itraconazole and amphotericin B...

We report a rare case of phaehyphomycosis in a 71-year-old heart transplant recipient Togo native patient. Four months after the transplant, he presented painless nodules on the right heel with superficial ulceration. The polyphasic identification uncovered a rare cause of phaehyphomycose: V. botryosa. The treatment combined surgical excision of the lesions and anti-fungal therapy with posaconazole. We discussed eleven reported cases in literature since 1990.

Cutaneous alternariosis is an uncommon fungal infection that most commonly presents in organ transplant patients on immunosuppressive therapy. There are no clinical trials or guidelines to guide treatment of this condition, however itraconazole is the most commonly used antifungal in published cases. Here we report on a case of cutaneous alternariosis in a renal transplant recipient treated with a newer antifungal, posaconazole. A review of published reports of cutaneous alternariosis since 2008 is also discussed...

This is a case report of concurrent of blastomycosis and pseudomycetoma in a 3 year-old Persian cat from Bangkok, Thailand. Histopathology from antemortem and postmortem samples revealed blastomycosis and dermatophyte pseudomycetoma. The PCR analysis of the formalin-embedded tissue of antemortem sample confirmed that blastomycosis was caused by Blastomyces dermatitidis. Dermatophyte infection was caused by Microsporum canis. According to the author's knowledge, this is the first case of Blastomyces dermatitidis and dermatophyte pseudomycetoma in South-East Asia...

A 65-year-old Japanese male had severe bronchial asthma had increased mold-containing sputum. Serum total IgE level had increased to 798 IU/mL and antigen-specific precipitating antibodies to P. luteum and P. notatum were present but not those reactive toward any species of Aspergillus. Chest computed tomography revealed central bronchiectasis and bronchial wall thickness. After antigen-specific provocation with 10 mg/mL of P. luteum, the patient developed asthma exacerbation, but not with A. fumigatus. We present a rare case of Penicillium-induced allergic bronchopulmonary mycosis caused by P...

Verruconis gallopava is an uncommon cause of phaeohyphomycosis. We describe an unusual case of disseminated V. gallopava infection in a renal transplant recipient involving the endocardium but without endocarditis, associated with fungaemia and infection in the skin, oral cavity, brain and lung. The isolate was first detected from blood cultures which is rare. Surgical resection of cardiac fungal mass was not possible. The patient died despite resolution of fungaemia and combination antifungal therapy.

Coccidioides species are endemic to the southwestern United States and typically cause a mild or asymptomatic primary infection. In some instances, infection can disseminate and involve the central nervous system with meningitis being the most common manifestation. Non-osseous spinal cord involvement is exceedingly rare. We report a case of disseminated coccidioidomycosis in an otherwise healthy 20 year old man with diffuse leptomeningeal enhancement, cerebrospinal fluid findings suggestive of meningitis, and intramedullary spinal cord abscesses...

An 85-year-old man complained of a 2-month history of pain on the left side of his face. Brain computed tomography (CT) and magnetic resonance imaging/magnetic resonance angiography did not clearly show any intracranial abnormality and only showed fluid effusion in his left sphenoid sinus. Filamentous fungi were detected from the left sphenoid sinus specimen. The isolate was Scedosporium apiospermum. He was empirically treated with voriconazole, to which the isolate was susceptible. His consciousness decreased rapidly...

Candida spp. are opportunistic unicellular fungi, known to cause oral, vaginal, lung and occasionally systemic infections. Characteristically, they colonize the oral cavity, the mucosal surfaces of the cheek, palate, and tongue. Usually harmless, oral Candidas may become pathogenic under immunosuppressive conditions, dentures presence, or salivary flow impairment. Accurate species identification is important because C. dubliniensis can rapidly develop fluconazole resistance. We report C. dubliniensis in an immunocompetent patient with a metal lingual frenulum piercing...

Mixed fungal infection and acquired echinocandin resistance of Candida spp. remain infrequent. In this study we have reported the case of a patient hospitalized for tuberculosis who experienced multiple infections due to three common Candida species (C. albicans, C. glabrata, C. tropicalis). Furthermore, consecutive isolates from blood cultures and heart valve were found resistant to azoles (C. tropicalis) and to echinocandin with either novel (C. tropicalis) or previously described (C. albicans) missense mutations in the Fks gene...

Cryptococcosis is a fungal disease which has been characterized by its identified risk groups. There are many risk factors identified. We present a surprising four cases of disseminated cryptococcosis in intravenous drug abuse (IVDA) patients in a short period of time and in one geographical area, this observation suggest that there may be a new association with IVDA and cryptococosis.

Paracoccidioidomycosis is a systemic fungal infection caused by Paracoccidioides brasiliensis and endemic in certain areas of Central and South America. We report a case of a 62-year-old-man with a complex history of tuberculosis and imaging findings of a cerebral lesion and bilateral adrenal enlargement. Biopsy of adrenal gland revealed Paracoccidioides brasiliensis. This case highlights the importance of travel history for diagnosis of paracoccidioidomycosis in non-endemic areas and emphasizes the clinical and histopathological similarities with tuberculosis...

Arthrographis kalrae is a hyalin fungus. It is a saprophyte of the environment, mainly found in soil and compost. In recent years, cases of opportunistic infections attributed to this pathogen have been described. Our patient was a 19-year-old woman with cystic fibrosis. She presented a bacterial and fungal pulmonary colonization with Aspergillus fumigatus and Arthrographis. kalrae. After her lung transplantation, she developed an A. kalrae fungemia, treated with caspofungin 50 mg/day associated to liposomal amphotericin B i...

Disseminated histoplasmosis affecting the adrenal gland(s) of immunocompetent adults is a very rare infection. Here, we present a case of bilateral adrenal histoplasmosis in an immunocompetent, 62-year-old gentleman from Texas along with a brief review of the published literature. Given the risk of patient decompensation secondary to adrenal insufficiency and the wide availability of effective treatments, adrenal histoplasmosis must be considered even in immunocompetent adults who acquire adrenal masses.

We document the first case of haematogenous cerebral spread in Rhizopus arrhizus rhino-orbital mucormycosis, and of posaconazole related adrenal insufficiency. A patient presenting with diabetic ketoacidosis and sinusitis was treated with right medial maxillectomy, ethmoidectomy and IV liposomal amphotericin. Orbital exenteration was performed after intraorbital spread of infection. IV caspofungin and posaconazole was added but complicated by adrenal insufficiency. MRI revealed a new left lentiform nucleus and thalamus rim-enhancing lesion indicating haematogenous cerebral spread...
