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 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...

Histoplasma capsulatum var. farciminosum, the causative agent of epizootic lymphangitis (EZL), is endemic in parts of Africa. Diagnosis based on clinical signs and microscopy lacks specificity and is a barrier to further understanding this neglected disease. Here, a nested PCR method targeting the internal transcribed spacer (ITS) region of the rRNA operon was validated for application to equine clinical samples. Twenty-nine horses with signs of EZL from different climatic regions of Ethiopia were clinically examined...

Disseminated histoplasmosis most commonly occurs in immunosuppressed individuals and involves the skin in approximately 6% of patients. Cutaneous histoplasmosis with an intraepithelial-predominant distribution has not been described. A 47-year-old man was admitted to our institution with fever and vancomycin-resistant enterococcal bacteremia. He had been diagnosed with T-cell prolymphocytic leukemia 4 years earlier and had undergone matched-unrelated-donor stem cell transplant 2 years earlier; on admission, he had relapsed disease...

We present the case of a 46 years old gentleman with longstanding ulcerative lesion of the right upper eyelid. Biopsy of the lesion revealed intracellular periodic acid-Schiff positive round to oval organisms with a surrounding clear halo suggestive of histoplasmosis. Histoplasma capsulatum specific polymerase chain reaction was positive. The patient was treated with oral antifungals and showed a prompt response to treatment. We report this rare case of primary cutaneous histoplasmosis of the eyelid in an otherwise healthy adult patient...

Histoplasmosis, caused by the dimorphic fungus Histoplasma capsulatum, is a disease of protean manifestations and of global distribution. Although increasingly reported in Asia, there are few reports from the Philippines. Here, we describe a case of microbiologically diagnosed histoplasmosis, probably acquired from the Philippines, in a returning traveler who presented with a right foot wound and papular rash. The final diagnosis was disseminated histoplasmosis with cutaneous and bone involvement, both unusual manifestations of the disease...

Histoplasmosis is an endemic systemic mycosis caused by the dimorphic fungus Histoplasma capsulatum. In immunocompromised patients, histoplasmosis generally occurs as an opportunistic disease, with dissemination to various organs. Cutaneous involvement is observed in 38% to 85% of cases, with oral mucosal involvement in 30% to 60% of cases. This article describes the case study of a 32-year-old woman who presented an extensive tongue ulcer due to histoplasmosis and had the HIV infection diagnosis based on laboratory tests requested by the dentist...

The information on the prevalence of fungal infections in the Caribbean region including Trinidad and Tobago (population 1,339,000 million) is scanty. Tinea capitis is common in children, being predominant in those of African descent, with no definitive estimate. Asthma is also common affecting 77,000-139,000 adults with an estimated 1927-3491 affected by allergic bronchopulmonary aspergillosis (ABPA) and 2544-4608 with severe asthma and fungal sensitisation (SAFS). An estimated 23,763 women have ≥4 attacks of vaginal candidiasis annually...

Infections with Histoplasma capsulatum are rare in Germany, and mostly imported from endemic areas. Infections can present as localized or disseminated diseases in immunocompromised as well as immunocompetent hosts. A travel history may be a major clue for diagnosing histoplasmosis. Diagnostic tools include histology, cultural and molecular detection as well as serology. Here we present four cases of patients diagnosed and treated in Freiburg between 2004 and 2013 that demonstrate the broad range of clinical manifestations of histoplasmosis: an immunocompetent patient with chronic basal meningitis; a patient with HIV infection and fatal disseminated disease; a patient with pulmonary and cutaneous disease and mediastinal and cervical lymphadenopathy; and an immunosuppressed patient with disseminated involvement of lung, bone marrow and adrenal glands...

A 70-year-old male presenting a 3-month history of genital painless erythematous nodules in the balanopreputial sulcus was referred to our service. Histopathological exam presented a chronic dermatitis with epithelioid granulomas and Grocott staining revealed numerous fungal structures with a suggestive morphology of Histoplasma sp. Cultures evidenced Histoplasma capsulatum var. capsulatum. Treatment with oral itraconazole led to complete remission of lesions.

In a retrospective study, we investigated 52 formalin-fixed, paraffin-embedded (FFPE) samples from cats with histologically confirmed cutaneous and subcutaneous mycoses to determine if the pathogens could be identified by molecular methods. Aim of the study was to obtain a deep understanding of the spectrum of infectious agents, which, as we hypothesized, was not available by histopathology alone. Detection of feline and fungal DNA was achieved in 92.3% and 94.2% of the samples, respectively. Most of the subcutaneous infections in cats were caused by Alternaria spp...

OBJECTIVES: African histoplasmosis, caused by Histoplasma capsulatum var. duboisii, is an invasive fungal infection endemic in Central and West Africa. Cases seen outside Africa are generally imported. We report a disseminated purely cutaneous form of this infection in an otherwise healthy person from Kerala, in southern India. METHODS: A 59-year-old farmer presented with asymptomatic, generalized, reddish skin lesions of five months in duration. Dermatologic examination revealed multiple erythematous papules and plaques of varying sizes, predominantly over the trunk and upper limbs...

This is a case of primary cutaneous histoplasmosis, without any systemic involvement, that occurred without a history of trauma. Due to its rarity and varied clinical presentation, there is much difficulty in diagnosis of this disease entitiy, especially in differentiating it from pyoderma gangreosum. This patient required deep tissue sampling and a DNA probe for Histoplasma to establish a time-sensitive diagnosis as multiple superficial biopsies are nondiagnositic.

We report an imported case of Histoplasma capsulatum var. duboisii (H. duboisii) infection in a white French woman revealed by cutaneous lesions of the scalp, 18 years after her last stay in West and Central Africa. Asymptomatic bilateral pulmonary infiltrates were discovered on thoracic computed tomography. Skin biopsy allowed the positive diagnosis showing the typical yeasts; culture of biopsy specimens was positive for H. capsulatum. In the absence of criteria of severity, the patient was treated for one year with oral itraconazole 400mg/day...

The frequency of histoplasmosis among solid organ transplant (SOT) recipients appears to be low where there are only a few case series, mostly among renal and liver transplant recipients. Herein we report a case of a 44-year-old woman who underwent a living-related renal transplant 18 years prior to evaluation, developed a nodule after followed by ulceration upon her posterior right leg and a second one upon her left leg 3 months and 2 months before her hospitalisation, respectively. The biopsy of lesion revealed the presence of Histoplasma spp...

Histoplasmosis is caused by the dimorphic fungus Histoplasma capsulatum.Primary infection occurs through inhalation of spores from the air. Immunocompetent individuals are usually asymptomatic, but may develop pulmonary disease. Immunocompromised patients tend to present systemic histoplasmosis with cutaneous lesions occurring by secondary invasion. In this case report, we describe a probable primary cutaneous histoplasmosis (PCH) in a patient with adult onset Still's disease under immunosuppression.

Primary cutaneous histoplasmosis in a HIV positive patient ie isolated cutaneous involvement without any deeper structures is a very rare entity. Only a handful cases have been reported worldwide. This patient presented with cutaneous lesion simulating Molluscum but histopathology revealed Histoplasma capsulatum. The patient had no deep organ involvement. The patient was put on Itraconazole which caused rapid dissolution of the lesions. He was subsequently put on HAART and discharged.

Histoplasmosis is a fungal infection caused by a dimorphic fungus, Histoplasma capsulatum. Most infections occur after inhalation of fungal spores. A wide variety of clinical manifestations can occur depending on the host response and the extent of inoculation. We report a case of probable cutaneous histoplasmosis after trauma in a 26-year-old man from Paraguay who was also infected with the human immunodeficiency virus. Diagnosis was based on histological and mycological examination. No systemic involvement was found...

INTRODUCTION: Histoplasmosis, a disease due to Histoplasma capsulatum, is an invasive opportunistic fungal infection, endemic in Africa. So, the occurrence of african histoplasmosis associated with HIV infection has been rarely reported despite the high prevalence of both pathogens in this area. We report the first case of disseminated african histoplasmosis in an HIV-infected Senegalese patient. OBSERVATION: A patient, 50-year-old has been admitted for umbilicate, necrotic and disseminated papulonodular lesions with oral infection, fever and reduction of total body mass...
