A 44-year-old female presented to her general dentist with the chief complaint of a painful mouth sore of 2 weeks duration. Clinical examination revealed an irregularly shaped ulcer of the buccal and lingual attached gingiva of the anterior mandible. A biopsy was performed and microscopic evaluation revealed histoplasmosis. Histoplasmosis, caused by Histoplasma capsulate, is the most common fungal infection in the United States. Oral lesions of histoplasmosis are generally associated with the disseminated form of histoplasmosis and may present as a fungating or ulcerative lesion of the oral mucosa...

BACKGROUND: The prevalence of the Histoplasma capsulatum var. capsulatum (Hcc) histoplasmosis may be underestimated West Africa, both because the diagnosis is not mentioned in the early stages of the disease and due to limited biological resources available. CASE REPORT: We report a case of disseminated histoplasmosis due to Hcc in a Senegalese HIV patient. The diagnosis was suspected following the demonstration of small encapsulated yeasts within neutrophils on a thin blood smear...

Histoplasmosis is the most common endemic mycoses among HIV-infected people. Patients with suppressed cell immunity mainly due to HIV are at increased risk of disseminated disease. Dermatological manifestations of immune reconstitution inflammatory syndrome (IRIS) and cutaneous manifestations of histoplasmosis similar to an IRIS event have been previously described. We report the case of a 43-year-old male who presented with cutaneous disseminated histoplasmosis due to Histoplasma capsulatum var. capsulatum 4 months after the onset of the antiretroviral therapy and some improvement in the immune reconstitution...

A 6-year-old boy presented with a 3-month history of high-grade fever and night-sweats but without chills/rigors. On examination, he had moderate hepatosplenomegaly with multiple enlarged cervical and axillary lymph nodes. His hemogram revealed anemia and marked eosinophilia. Initial investigations were negative, except anti-HCV IgG antibodies, that were positive. Bone marrow aspirate showed a single histiocyte containing suspicious intracellular yeast-like forms. Cervical lymph node aspiration revealed a heavy load of intra- and extra-cellular Histoplasma spp...

In Bangladesh there are several published papers on superficial mycoses. Deep mycoses are also recognized as an important emerging problem. Here, we estimate the annual incidence and prevalence of serious fungal infections in Bangladesh. Demographic data were obtained from world population reports and the data on TB and HIV extracted from the online publications on tuberculosis in Bangladesh and Asia Pacific research statistical data information resources AIDS Data HUB. All the published papers on fungal infections in Bangladesh were identified through extensive search of literature...

We present a case of antigen-negative disseminated histoplasmosis manifesting as an isolated ileal stricture in a patient on chronic infliximab and methotrexate. Diagnosis can be challenging due to imperfect tests, and this condition should remain in the differential, even with negative testing. Mortality of untreated disseminated histoplasmosis can be as high as 80%.

Granulomas of the skin may be classified in several ways. They are either infectious or non-infectious in character, and they contain areas of necrobiosis or necrosis, or not. Responsible infectious agents may be mycobacterial, fungal, treponemal, or parasitic organisms, and each case of granulomatous dermatitis should be assessed histochemically for those microbes. In the non-infectious group, examples of necrobiotic or necrotizing granulomas include granuloma annulare; necrobiosis lipoidica; rheumatoid nodule; and lupus miliaris disseminates faciei...

BACKGROUND: Tumor necrosis factor antagonist inhibitors have transformed the approach to patients with severe autoimmune conditions, such as rheumatoid arthritis. Although the therapy can be highly effective, TNF-α inhibitors are associated with an increased risk of opportunistic infections. CASE PRESENTATION: Here, we report a case of concomitant disseminated histoplasmosis and tuberculosis in a 65-year-old female with rheumatoid arthritis treated with TNF-α inhibitor...

Deaths from AIDS (1 500 000 in 2013) have been falling more slowly than anticipated with improved access to antiretroviral therapy. Opportunistic infections account for most AIDS-related mortality, with a median age of death in the mid-30s. About 360 000 (24%) of AIDS deaths are attributed to tuberculosis. Fungal infections deaths in AIDS were estimated at more than 700 000 deaths (47%) annually. Rapid diagnostic tools and antifungal agents are available for these diseases and would likely have a major impact in reducing deaths...

65 year-old-male presented with a one-week history of high grade fever, fatigue and confusion which began abruptly two days after a cystoscopy procedure. Past medical history included pulmonary sarcoidosis diagnosed by mediastinal lymph biopsy, diabetes and hypertension. On admission he was febrile and confused with stable vital signs. Initial workup included negative Head CT and lumbar puncture. Blood work revealed normal metabolic and liver function tests with progressive anemia, thrombocytopenia and atypical lymphocytosis of 15-20%...

To compare clinical features, diagnosis and therapeutic effect between pulmonary histoplasmosis and progressive disseminated histoplasmosis.
 Methods: A retrospective analysis for 12 cases of hospitalized patients with histoplasmosis, who was admitted in Xiangya Hospital, Central South University during the time from February 2009 to October 2015, was carried out. Four cases of pulmonary histoplasmosis and 8 cases of progressive disseminated histoplasmosis were included. The differences of clinical features, imaging tests, means for diagnosis and prognosis were analyzed between the two types of histoplasmosis...

Histoplasma capsulatum causes a spectrum of manifestations from asymptomatic to fatal disseminated disease. Disseminated histoplasmosis is mostly seen in endemic areas among immunocompromised patients such as those with AIDS. Here, we present a patient living in a non-endemic area with previously undiagnosed diabetes mellitus, who presented with septic shock and diabetic ketoacidosis (DKA), and was ultimately diagnosed with disseminated histoplasmosis. The patient rapidly recovered on administration of intravenous liposomal amphotericin followed by oral itraconazole...

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.

A retrospective study was carried out on 171 cases of disseminated histoplasmosis diagnosed in HIV/AIDS patients during the period 2009-2014. Although HIV diagnosis rates remained stable over the study period, a sensible increase in the number of histoplasmosis cases was observed in the last three years. Disseminated histoplasmosis was prevalent in males with an average age of 37.8 years. At diagnosis, only 54/171 (31.6%) were receiving HAART, and CD4+ T-lymphocyte counts ranged from 4 to 264 cells/upsilon...

Histoplasmosis is well characterized as an endemic fungal disease restricted to certain areas of the USA. In Middle Europe, most patients present with acute pulmonary symptoms after travelling to endemic areas. Here, we want to illustrate the case of a 67-year-old man who presented with persistent oral ulcers, hoarseness, dysphagia, diarrhea, and weight loss to our Department of Otorhinolaryngology in December 2014. He was a retired construction worker and had a history of soil-disruptive activities in Africa and Middle and South America during employment...

Histoplasmosis is a systemic fungal infection caused by dimorphic fungus, Histoplasma capsulatum. Immunocompetent individuals usually have self-limiting or localized disease whereas immunocompromised individuals develop disseminated disease. The occurrence of progressive disseminated histoplasmosis in juvenile systemic lupus erythematosus is extremely rare with only one reported case in literature showing such association. Therefore, we report a case of severe opportunistic fungal infection caused by Histoplasma in a 13-year-old girl who was diagnosed with juvenile lupus erythematosus, subsequently developed septic shock and died of the disease despite of aggressive antifungal therapy...

The diagnosis of progressive disseminated histoplasmosis is often a challenge to clinicians, especially due to the low sensitivity and long turnaround time of the classic diagnostic methods. In recent years, studies involving a variety of non-culture-based diagnostic tests have been published in the literature. We performed a systematic review by selecting studies evaluating non-culture-based diagnostic methods for progressive disseminated histoplasmosis. We searched for articles evaluating detection of antibody, antigens, as well as DNA-based diagnostic methods...

In immunocompromised patients, histoplasmosis may present as disseminated disease. We present a 52-year-old Caucasian male with symptoms of dyspepsia, postprandial epigastric pain, nausea, and nonbloody diarrhea. Upper and lower gastrointestinal endoscopies were suspicious for inflammatory bowel disease (IBD); however, biopsies were consistent with histoplasmosis, specifically in the duodenum.
