Objective: Endoscopic ultrasound-guided fine-needle aspiration cytology (EUS-FNAC) is a precise and safe technique that provides both radiological and pathological diagnosis with a better diagnostic yield and minimal adverse events. EUS-FNAC led to the remarkable increase in the detection rate of incidentaloma found during radiologic staging or follow-up in various malignancy or unrelated conditions. Aims: We did this preliminary study with an aim to evaluate the role of EUS-FNA in diagnosing and classifying adrenal lesions, clinical impact, and compare the outcome with the previously published literature...

We report a case of a Puerto Rican male with advanced AIDS who presented with multiple falls and pancytopenia. Magnetic resonance imaging (MRI) of the brain, as initial workup, revealed 2 ring-enhancing brain lesions. Initial cerebrospinal fluid analysis revealed minimal cells, mildly elevated protein, and no organism seen on gram stain. Due to prohibitive thrombocytopenia, brain biopsy was deferred. He had neither clinical nor radiographic improvement despite empiric therapy for both toxoplasmosis and bacterial abscesses...

Mud runs are an increasingly popular recreational fitness activity across the United States, combining a running race through an obstacle course with submersion in mud. Recent reports estimate 4 million people have participated in these types of events over the last 5 years. We describe an atypical case of myocarditis and multiorgan failure from disseminated histoplasmosis in a previously healthy pediatric patient, likely acquired during participation in a mud run. Although cases of histoplasmosis-associated endocarditis and pericarditis have been reported in the literature, cases of histoplasmosis myocarditis are rare...

Fungal infections are frequent in Cameroon, and invasive fungal infections are sometimes detected, usually in HIV-infected patients. For these reasons, we have estimated the burden of fungal infections. Using published literature and population estimates for the at-risk group, we used deterministic modelling to derive national incidence and prevalence estimates for the most serious fungal diseases. HIV infection is common and an estimated 120,000 have CD4 counts <200 × 10⁶/mL and commonly present with opportunistic infection...

Central nervous system (CNS) involvement occurs in 5 to 10% of individuals with disseminated histoplasmosis. Most experience has been derived from small single center case series, or case report literature reviews. Therefore, a larger study of central nervous system (CNS) histoplasmosis is needed in order to guide the approach to diagnosis, and treatment.A convenience sample of 77 patients with histoplasmosis infection of the CNS was evaluated. Data was collected that focused on recognition of infection, diagnostic techniques, and outcomes of treatment...

Epidemiological cutoff values (ECV) have been used as a tool to detect the acquisition of resistance mechanisms to antifungal drugs. In this context, the objective of this study was to determine the epidemiological cutoff values for classic antifungals against Histoplasma capsulatum var. capsulatum isolates from HIV-infected patients with the diagnosis of disseminated histoplasmosis. Initially, the minimum inhibitory concentrations (MIC) for amphotericin B, itraconazole, fluconazole, voriconazole and caspofungin against 138 isolates of H...

Extracerebral toxoplasmosis, with pulmonary involvement and shock, is a rare form of toxoplasmosis in patients with advanced AIDS. It can mimic pneumocystosis, histoplasmosis, and disseminated tuberculosis, and should be considered in the differential diagnosis of causes of respiratory failure and fulminant disease in this group of individuals, especially in areas where the Toxoplasma gondii infection is highly prevalent and in those without proper use of antimicrobial prophylaxis. We report the case of a 46-year-old male patient who presented to the emergency department with uremia, requiring urgent dialysis...

Histoplasmosis is an important cause of mortality in patients with AIDS, especially in countries with limited access to antiretroviral therapies and diagnostic tests. However, many disseminated infections in Latin America go undiagnosed. A simple, rapid method to detect Histoplasma capsulatum infection in endemic regions would dramatically decrease time to diagnosis and treatment, reducing morbidity and mortality. The aim of this study was to validate a commercial monoclonal Histoplasma galactomannan (HGM) ELISA (Immuno-Mycologics [IMMY], Norman, Oklahoma, USA) in two cohorts of people living with HIV/AIDS (PLHIV)...

Introduction: Gastrointestinal histoplasmosis (GH) is a well-described albeit uncommon disease. It is found almost exclusively in the immunocompromised host, especially those with untreated HIV and low CD4 counts. Presentation with intestinal perforation is seen mostly commonly in the colon. We present a patient with jejunal perforation, and there have been only 3 previous cases reported in the literature. Case: A 39-year-old male with known, untreated HIV presented to the ED with an acute abdomen after experiencing worsening intermittent abdominal pain for 2 months before that was associated with nausea, vomiting, diarrhea, and weight loss...

Biologic agents are effective treatments for rheumatoid arthritis but are associated with important risks, including severe infections. Tumor Necrosis Factor (TNF) α inhibitors are known to increase the risk of systemic fungal infections such as disseminated histoplasmosis. Abatacept is a biologic agent with a mechanism different from that of TNFα inhibitors: It suppresses cellular immunity by competing for the costimulatory signal on antigen-presenting cells. The risk of disseminated histoplasmosis for patients on abatacept is not known...

A woman in her late 60s with disseminated histoplasmosis was treated with posaconazole since first-line therapies were not tolerated. She subsequently presented with decompensated heart failure, hypertension, and hypokalemia. Labs revealed low renin and aldosterone levels. A potential mechanism is inhibition of the enzyme 11 beta-hydroxysteroid dehydrogenase 2, with resultant apparent mineralocorticoid excess.

Histoplasmosis is a fungal infection caused by a dimorphic fungus, Histoplasma capsulatum. We report a first case of disseminated histoplasmosis in a 34-year-old woman, infected with human immunodeficiency virus (HIV), originating from Ivory Coast and living in Tunisia for 4 years. She was complaining from fever, chronic diarrhoea and pancytopenia. The Histoplasma capsulatum var. capsulatum was identified by direct microscopic examination of the bone marrow. She was treated by Amphotericin B, relayed by itraconazole...

The dermatological manifestations of disseminated histoplasmosis present in about 17% of the cases, is a challenge for its diagnosis. We report the case of a patient from the northern coast of Peru, who presented diffuse dermal lesions, erythema-violaceous nodules, and ulcers histopathologically compatible with the infection of the genus Histoplasma var. capsulatum.

A 46-year-old Dominican man, known to have HIV, presented with constitutional symptoms of two week's duration. The patient was found to have cytopenias, significantly elevated ferritin level and lymphadenopathy. Biopsies and laboratory studies met the criteria for hemophagocytic lymphohistiocytosis (HLH). A concomitant diagnosis of histoplasmosis was confirmed as the trigger for HLH and treatment resulted in clinical improvement and resolution of symptoms.

Histoplasmosis is a systemic mycosis caused by the dimorphous fungus Histoplasma capsulatum (H. capsulatum). The fungus enters the body through the respiratory tract in the form of microconidia, which are transformed into intracellular yeast-like structures in the lungs before disseminating hematogenously. Primary infection is usually asymptomatic and self-resolving. Some patients develop severe disease with acute or chronic respiratory involvement. Immunosuppressed patients, mainly those with altered cellular immunity, may have disseminated disease with variable mucocutaneous involvement characterized by papules, nodules, gummas, or ulcers with a granulomatous base...

A total of 23/45 (51%) patients with AIDS and histoplasmosis from Medellín, Colombia had other infections. Tuberculosis was the most common (n = 16/23, 70%). Pneumocystosis and cryptococcosis were found in three patients each (13%), bacterial infection and cytomegalovirus occurred each in two patients (9%) while toxoplasmosis, herpes virus and esophageal candidiasis were recorded in one patient each (4%). Of all co-infected patients, 18/23 (78%) had one, four (17%) had two and one (4%) had three additional opportunistic infections...

Disseminated histoplasmosis and hemophagocytic lymphohistiocytosis show overlapping features, which require careful contextual interpretation. Histopathologic evaluation can potentially rapidly identify cases of possible histoplasmosis. A high index of clinical suspicion, particularly in endemic areas and in a setting of immunosuppression, is critical to appropriate diagnosis and treatment.

Fungal diseases kill more than 1.5 million and affect over a billion people. However, they are still a neglected topic by public health authorities even though most deaths from fungal diseases are avoidable. Serious fungal infections occur as a consequence of other health problems including asthma, AIDS, cancer, organ transplantation and corticosteroid therapies. Early accurate diagnosis allows prompt antifungal therapy; however this is often delayed or unavailable leading to death, serious chronic illness or blindness...

A 30-year-old Javanese-Indonesian man was admitted with complaints of 3 months persistent fever, weight loss, and fatigue. He had never known his past history of unprotected HIV until the admission. His only risk factor is unsafe sex. The patient seemed well nourished. Physical examination revealed blood pressure 100/60 mmHg, pulse 100 beats per minute, respiratory rate 20 times per minute, and temperature 38.8°C. Multiple cervical and inguinal lymphadenopathies were also found. Electrocardiogram showed anterolateral ischemic finding, whereas chest X-ray were normal...
