BACKGROUND: Cryptococcosis is an opportunistic infection caused by the encapsulated yeast Cryptococcus neoformans and most remarkably manifests in HIV-infected individuals, especially in the settings of very low CD4 count. Development of cryptococcosis in HIV-uninfected individuals is exceedingly rare and usually signifies a marked immunodeficiency. Cryptococcosis in association with myasthenia gravis or thymoma has been previously documented in only very few cases in the literature. CASE PRESENTATION: We reported a complicated case of severe cutaneous cryptococcosis in a 39-year-old Vietnamese male patient with myasthenia gravis on long-term immunosuppressive therapy...

We clarified the performance of a cryptococcal glucuronoxylomannan (GXM) antigen test using bronchoalveolar lavage fluid (BALF) samples, in an HIV-negative Japanese population. Between March 2008 and December 2014, we examined cryptococcal GXM antigens in both serum and BALF specimens from 429 cases at Nagasaki University hospital. The diagnoses, underlying diseases, chest computed tomography findings, and cryptococcal GXM antigen test results were retrospectively investigated. Twenty-three patients were confirmed to have pulmonary cryptococcosis, another six were clinically diagnosed with cryptococcosis because they were seropositive for the GXM antigen, and five possible cryptococcosis cases had BALF samples that were positive for the GXM antigen and serum samples that were negative...

INTRODUCTION: Opportunistic pneumonias are a major cause of mortality and morbidity in Human Immunodeficiency Virus (HIV) reactive patients. Despite the significant role that fungi play in causation of this opportunistic mycoses, very few Indian studies have attempted to investigate the burden and aetiological spectrum of HIV/AIDS-associated fungal pneumonias. AIM: To document the prevalence of fungal aetiology in HIV/AIDS-related opportunistic pneumonias in an Indian setting; and to elucidate the various fungal opportunists responsible for the same...

Despite the strong association between Cryptococcus neoformans infection and the Human immunodeficiency virus (HIV) status of patients globally, most cryptococcosis cases in Far East Asia occur in non-HIV individuals. Molecular epidemiological studies, using multilocus sequence typing (MLST), have shown that more than 95% of cryptococcal strains belong to a specific subtype of VNI. However, this association has never been specifically examined in other parts of Asia. Therefore, in this study, we investigated the VNIc/ST5 genotype distribution among cryptococcosis patients in Thailand...

Cryptococcosis is a fungal infection caused by Cryptococcus neoformans that tends to affect immunocompromised individuals. The fungi are mostly acquired by inhalation, which leads to an initial pulmonary infection. Later, other organs - such as the central nervous system and the skin - can be affected by hematogenous spread. In addition, cutaneous contamination can occur by primary inoculation after injuries (primary cutaneous cryptococcosis), whose diagnosis is defined based on the absence of systemic involvement...

BACKGROUND: Deep cutaneous fungal infections, including subcutaneous mycoses and systemic fungal infection with cutaneous involvement, cause significant morbidity and mortality in light of increasing immunocompromised patients and global warming. Although a few studies reviewed deep fungal infections in temperate regions, a relevant study in tropical regions is lacking. We evaluated features of deep cutaneous fungal infections in southern Taiwan among the tropical regions. METHODS: We retrospectively reviewed all histopathological specimens with deep cutaneous fungal infections in a single referral center from 2001 to 2014 and successfully identified 23 cases...

A 73-year-old man with type 2 diabetes mellitus and end-stage renal disease was diagnosed with acute myocardial infarction. He required continuous dialysis after percutaneous coronary intervention. Subsequently, multiple nodules were discovered in both lungs for the first time, and Cryptococcus neoformans was isolated from the patient's sputum, blood, bilateral pleural fluid, and cerebrospinal fluid cultures, resulting in a diagnosis of disseminated cryptococcosis. This case represents an invaluable example of disseminated cryptococcosis with rapidly growing lung nodules in a dialysis patient, and illustrates that dialysis causes innate immune disorder and the reactivation of cryptococcosis...

Cryptococcosis is an invasive fungal infection that is common in immunocompromised patients. A 22-year-old woman with Ewing sarcoma in the right proximal humerus was treated by resection and chemotherapy. Computed tomography detected a small nodule in her right upper pulmonary lobe after completion of her chemotherapy. With the presumptive diagnosis of pulmonary metastasis, she underwent resection. Evaluation of the resected specimen revealed pulmonary cryptococcosis, and the patient was treated with oral fluconazole for 18 weeks...

Cryptococcosis is a fungal infection of opportunistic behavior that is unusual in immunocompetent patients. We report a rare case of disseminated cryptococcosis with cutaneous involvement in an immunocompetent individual. During hospitalization, Cryptococcus gattii was isolated from skin lesions, lung and spinal fluid. The diagnosis of disseminated cryptococcosis was confirmed and treatment was established. The patient showed improvement. Due to the probable clinical severity of the disease and the possibility that skin lesions may be the first manifestation of this illness, prompt diagnosis must be established and treatment provided...

Cryptococcosis is an infection that may be lethal in patients with nephrotic syndrome (NS). However, there is relatively limited epidemiological and clinical data about cryptococcosis in NS patients. We performed a pooled analysis to systemically summarize the epidemiology, risk factors, clinical and laboratory characteristics, treatments and outcomes of cryptococcosis in NS patients. Using data pooled from our hospital and studies identified via searches of three literature databases, 17 cases were identified for inclusion in this analysis...

A case of disseminated cryptococcus infection in an immunocompetent host is described. The present case attests to the importance of using a cautious approach for the diagnosis of granulomatous lymphadenitis. The patient was initially misdiagnosed and treated as disseminated tuberculosis. Later the patient developed visual loss and skin lesions. Periodic Acid Schiff stained sections of lymph node biopsy and cerebrospinal fluid culture established the diagnosis.

Cryptococcosis is a mycosis caused by yeasts of genus Cryptococcus, mainly the species C. neoformans and C. gattii that can affect humans and animals. These yeasts are widely distributed in the environment and are typically associated with avian droppings and decaying wood. Most infections are related to the respiratory tract, but the central nervous system and cutaneous lesions are also reported in the literature. The present report is a case of cryptococcosis in an 18-month-old unspayed female English Bulldog with the main complaint of weight loss and diarrhea...

BACKGROUND: Cryptococcal infections have been mostly associated with immunocompromised individuals, 80-90% of whom have been HIV-positive patients. Increasingly, cryptococcal infections are being reported in cirrhotic patients who are HIV-negative. The underlying immunologic defects in cirrhotic patients seem to play an important role in predisposing them to cryptococcosis and affecting their morbidity and mortality. CASE PRESENTATION: We present a case of disseminated cryptococcosis in an HIV-negative patient with underlying cirrhosis, who had rapid worsening of his hyponatremia with renal failure and was unable to recover, despite aggressive measures...

BACKGROUND: An infectious disease (ID) consultation is often obtained to treat patients with cryptococcosis due to the complex nature of the disease, but has never been demonstrated to impact outcomes. METHODS: We assembled a retrospective cohort of 147 consecutive cases of cryptococcosis in patients without HIV. Patients who were diagnosed less than 24 hours prior to death were excluded. Survival analysis was performed with Cox regression with survival censored past 90 days...

Cryptococcosis has been one of the most common opportunistic infections and causes of mortality among HIV-infected patients, especially in resource-limited countries. Cryptococcal meningitis is the most common form of cryptococcosis. Laboratory diagnosis of cryptococcosis includes direct microscopic examination, isolation of Cryptococcus from a clinical specimen, and detection of cryptococcal antigen. Without appropriate treatment, cryptococcosis is fatal. Early diagnosis and treatment is the key to treatment success...
