background: cryptosporidium and isospora are known as one of the main cause of diarrhea in both immunocompetent and immunocompromised subjects, all over the world. incidence of enteropathogens such as cryptosporidium spp. and isospora belli considerably has increased, since immunodeficiency virus (hiv) rapidly disseminated. in addition, cancer patients are highly susceptible to opportunistic in...

Mucormycosis is a fatal opportunistic fungal infection that typically occurs in immunocompromised patients. The classical manifestation of mucormycosis is a rhinocerebral infection, and although primary gastrointestinal infection is uncommon, it has an extremely high mortality rate in immunocompromised patients. Furthermore, cases of gastrointestinal mucormycosis in an immunocompetent host are ...

Diphtheria is a rare cause of infection in highly vaccinated populations and may not be recognized by modern clinicians. Infections by nontoxigenic Corynebacterium diphtheriae are emerging. We report the first case of necrotizing epiglottitis secondary to nontoxigenic C diphtheriae. A fully vaccinated child developed fever, poor oral intake, and sore throat and was found to have necrotizing epi...

INTRODUCTION Fungal infections in the immunocompromised host are fairly common. Of the mycoses, Fusarium species are an emerging threat. Fusarium infections have been reported in solid organ transplants, with three reports of the infection in patients who had received renal transplants. To the best of our knowledge, this is the first case of an isolated cutaneous lesion as the only form of infe...

BACKGROUND Although invasive pulmonary aspergillosis (IPA) is more prevalent in immunocompromised patients, critical care clinicians need to be aware of the occurrence of IPA in the nontraditional host, such as a patient with chronic lung disease. The purpose of this study was to describe the IPA patient with chronic lung disease and compare the data with that of immunocompromised patients. M...

Pseudomonas aeruginosa is a common bacterium, Gram-negative opportunistic pathogen capable of infecting humans with compromised natural defenses and causing severe pulmonary disease. It is one of the leading pathogen associated with nosocomial infections. It has a vast arsenal of pathogenicity factors that are used to interfere with host defenses. Pathogenesis in P. aeruginosa facilitates adhes...

Aspergillosis may complicate the course of a patient in an immunocompromised state. However, Aspergillus infection is rarely encountered in an immunocompetent host. We present an extremely rare case of Aspergillus chest wall involvement associated with extensive mediastinal lymphadenopathy in an immunocompetent host. A chest wall lesion was the initial indication of underlying nodal disease. We...

Lemierre's syndrome is a rare septic thrombophlebitis of the internal jugular vein with frequent metastatic complications following an acute oropharyngeal infection. Immunocompromised patients are at higher risk of developing this syndrome owing to the decreased host response and increased risk of oropharyngeal sepsis. We herein report a 24-year-old woman with severe lupus nephritis on immunosu...

Cryptococcus is a ubiquitous fungus and is known for causing meningitis and cutaneous infections in immunocompromised individuals. Disseminated cryptococcal infection is very rare and almost always found to occur in immunocompromised individuals especially in persons infected with HIV. This is particularly attributed to its capsulated spores. But there are few reported cases in which it has bee...

Sir, Graft-versus-host disease (GVHD) is a complex multisystem disorder that occurs in an immunocompromised host who is the recipient of histo-incompatible lymphocytes (1). Recent increases in transplantation procedures require careful follow-up of patients by dermatologists, as the skin is the earliest and most frequent target in GVHD. We report a case of chronic GVHD who exhibited only facial...
