Lobomycosis is a chronic skin mycosis endemic in Amazon regions characterized by chronic nodular or keloidal lesions caused by Lacazia loboi, an uncultivable fungus. Imported cases in nonendemic countries are rare and diagnosed after years. We describe a case of lobomycosis in a healthy 55-year-old Italian traveler who had acquired the infection during 5-day-honeymoon in the Amazon region of Venezuela in 1999. Several weeks after return, he recalled pruritus and papular skin lesions on the left lower limb, subsequently evolving to a plaque-like lesion...

Fungal infections have an important role in organ transplant recipients, and in some cases can be lethal. Blastomycosis is rare in kidney transplantation. We present a case of cutaneous blastomycosis in a kidney transplant recipient in Tunisia, a country outside the known endemic countries. This case, with the very uncommon and unexpected diagnosis of blastomycosis, demonstrates the diversity of infections in transplant recipients and reflects the importance of histologic and serologic tests in the immunocompromised patient...

Blastomycosis is an endemic fungal infection commonly found within the Mississippi and Ohio River basins and Great Lakes region. While patients typically present with acute pneumonia, Blastomyces dermatitidis has the potential to spread hematogenously, resulting in disseminated infection of multiple organs. In this report, we describe a 57-year-old male with disseminated blastomycosis acquired in South Dakota. The diagnostic evaluation was confounded by concern for malignancy given the involvement of multiple locations, including brain, lungs, adrenal glands, and testes...

Malignant glioblastoma multiform (GBM) is the most common primary malignancy of the brain in the U.S. Temozolomide (TMZ) is the cornerstone of management along with surgical resection and radiotherapy. Because of the reduction in the CD4+ lymphocyte count as a side effect of TMZ use, this patient population is under risk for opportunistic infections like Pneumocystis jiroveci. A male patient with newly diagnosed glioblastoma multiform presented with non-productive cough and chest pain. Before presentation, the patient received the standard therapy including surgical resection, radiation and TMZ...

The causal agents of blastomycosis, Blastomyces dermatitidis and Blastomyces gilchristii, belong to a group of thermally dimorphic fungi that can infect healthy and immunocompromised individuals. Following inhalation of mycelial fragments and spores into the lungs, Blastomyces spp convert into pathogenic yeast and evade host immune defenses to cause pneumonia and disseminated disease. The clinical spectrum of pulmonary blastomycosis is diverse. The diagnosis of blastomycosis requires a high degree of clinical suspicion and involves culture-based and non-culture-based fungal diagnostic tests...

There have been infrequent reports of isolated central nervous system blastomycosis. We report a case of intracranial epidural abscess secondary to Blastomyces dermatitidis in a patient residing in Rhode Island with a history of remote travel to an endemic area. The clinical, radiographic, and pathologic features of this unique case are reviewed.

Isolated blastomycosis hand infections are extremely rare, and are often clinically unsuspected, leading to delays in clinical diagnosis. Conclusive diagnosis often necessitates fungal cultures and histopathological demonstration of budding yeasts in tissues. In this report, we describe the rare occurrence of isolated blastomycotic hand infection, without any other organ involvement, in a 42-year-old male patient. Analyzing tissue specimens with frozen section has been shown in the past to demonstrate granulomatous inflammation and yeast forms of the organism; however, as demonstrated in this patient, the presence of pseudoepitheliomatous cells may deceptively appear as malignant, causing substantial concern and anxiety...

Fungal peritonitis is an uncommon complication in peritoneal dialysis patients. We report a case of blastomyces dermatitis peritonitis in a nonimmunocompromised peritoneal dialysis patient, who initially presented with symptoms of lower extremity weakness and altered mental status. Peritoneal blastomycosis is rare condition and not previously reported in end stage renal disease patients on peritoneal dialysis. Fungal peritonitis can present with subtle clinical findings so a high index of suspicion is needed as early detection and treatment may decrease mortality and morbidity...

We present a case of tissue invasive Trichophyton rubrum (T. rubrum) histologically mimicking blastomycosis in a patient with kidney transplant on chronic immunosuppression. Invasive dermatophyte infections are rare, and present a diagnostic challenge to the dermatopathologist due to atypical clinical and histopathological presentations.

A 7-year-old female golden retriever dog was presented with a 2-week history of coughing and inappetence. Examination, radiographs, and blood analysis showed classic evidence of blastomycosis, confirmed with the MVista EIA urine antigen test. A 2-month course of itraconazole and a course of mirtazapine, meloxicam, furosemide, and tetracycline resulted in a successful outcome.

Blastomycosis elicits a pyogranulomatous inflammatory response that involves a prominent recruitment of neutrophils to the site of infection. Although neutrophils are efficiently recruited to the site of infection, this event is paradoxically coupled with the host's inability to control infection by Blastomyces dermatitidis, the causative agent. The mechanisms underlying this characteristic pyogranulomatous response and inability of neutrophils to kill the yeast are poorly understood. We recently reported that the fungal protease dipeptidyl peptidase IVA (DppIVA) promotes B...

Oral and maxillofacial fungal infections can appear in high-risk patients, including those immunocompromised. This article explores common oral manifestations of fungal infections in the oral cavity as primary lesions or as a result of disseminated disease. By far the most common oral fungal infection experienced in dentistry is oral candidiasis, which is reviewed in depth from simple oral infections to invasive candidiasis. The review aids the dental practitioner in understanding the full scope of Candida infections and other fungal infections...

Blastomycosis is an uncommon infection caused by Blastomyces dermatitidis. While management is fairly straightforward, diagnosis can be quite challenging. We describe a case of a healthy 37-year-old man who presented with progressive mucocutaneous lesions, without lung or other systemic involvement. Treatment with itraconazole resulted in complete resolution of signs and symptoms. This case showcases the variety of blastomycosis clinical presentation and the importance of blastomycosis in the differential diagnosis of verrucous and papillomatous mucocutaneous lesions...

The diagnosis of blastomycosis during pregnancy is rare, but can carry significant clinical questions for both the infected mother and developing fetus. Furthermore, given its rarity, providers have little available data to help manage and counsel patients in this uncommon, yet serious, scenario. We present a case of blastomycosis in a woman at 38weeks' gestation and review all published cases of blastomycosis during pregnancy. It is our hope to provide a multidisciplinary understanding of the current knowledge surrounding the presentation, diagnosis, management, and outcome of this unusual infection...

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...

We present a 7-year-old boy with chronic meningitis caused by Blastomyces dermatitidis. A review of the literature revealed 32 cases of central nervous system blastomycosis in children between 1983 and 2016, of which 18 represented parenchymal disease of the brain or spinal cord. Blastomycosis affecting the central nervous system is rare but should be considered in children with chronic meningitis.

Blastomycosis-like pyoderma is a rare, cutaneous bacterial infection of skin, seen in malnourished individuals, in a poor state of health and manifests as vegetating skin lesions. It is an unusual tissue reaction possibly to bacterial infection, the most common organism being Staphylococcus aureus. This case report is of a 35-year-old male who presented with thick verrucous surfaced plaques and papules on trunk and extremities since 2 months. Investigations revealed anaemia with hypochromasia, neutrophilic leucocytosis, hypo-proteinemia and hypo-albuminemia with reversal of A/G ratio...
