Acute Toxoplasma gondii infection causes different clinical courses in 10-20% of cases. In immunocompetent patients, toxoplasmosis most often presents as asymptomatic cervical lymphadenopathy. Clinical manifestations such as pneumonia, myocarditis, hepatitis, and encephalitis are rarely reported. We present the case of an immunocompetent patient with a serious and complicated clinical course of...

The dematiaceous fungus Cladosporium cladosporioides (C. cladosporioides) is a widely distributed saprophyte that occasionally infects the lung, skin, eye and brain in both immunocompetent or immunosuppressed hosts. We report a rare case of an immunocompetent 56-year-old male patient who presents with a six-year history of onychomycosis caused by C. cladosporioides following trauma. The patient...

BACKGROUND Pasteurella multocida is a gram negative-penicillin sensitive bacterium and is part of normal respiratory microbiota of animals (e.g., cats and dogs) and some birds. Various infections in humans, such as cellulitis, rarely bacteremia, endocarditis, meningitis, and septic arthritis, are a result of domestic cat or dog bites. These infections are rarely seen in an immunocompetent perso...

Cryptococcal infection of the brain is commonly seen in immunocompromised patients but rarely considered as the differential diagnosis in immunocompetent patients. We present two cases of cryptococcosis involving the brain in immunocompetent patients, which strongly mimicked tuberculous infection in both conventional as well as advanced magnetic resonance (MR) imaging, and the disease was only ...

Invasive pulmonary aspergillosis (IPA) is rarely reported in patients who have normal immune function. Recently, IPA risk was reported in nonimmunocompromised hosts, such as patients with chronic obstructive pulmonary disease and critically ill patients in intensive care units. Moreover, influenza infection is also believed to be associated with IPA among immunocompetent patients. However, most...

Invasive aspergillosis has emerged as a major cause of life-threatening infections in immunocompromised patients. Recently, patients with chronic obstructive pulmonary disease, who have been receiving corticosteroids for a long period, and immunocompetent patients in the intensive care unit have been identified as nontraditional hosts at risk for invasive aspergillosis. Here, we report a case o...

INTRODUCTION Cytomegalovirus is a common virus responsible for a wide range of clinical manifestations. Hemolysis is a rare but potentially life-threatening complication of cytomegalovirus infection, described mostly in immunocompromised patients, the pathogenesis of which is still unclear.We performed a review of the literature regarding cases of hemolytic anemia during acute cytomegalovirus i...

BACKGROUND A review of published cases, in addition to a recently treated patient, is presented that describes the clinical features and outcomes of triazole therapy for vertebral aspergillosis in immunocompetent patients. METHODS Using the Medline database, cases of vertebral aspergillosis in immunocompetent patients treated with triazole were reviewed. Clinical and radiological findings, th...

BACKGROUND Pneumonia caused by shigellosis with or without typical dysentery in immunocompetent patients is an uncommon entity. CASE REPORT We describe a case of pneumonia in an immunocompetent, previously healthy middle-aged man from Switzerland without relevant travel history which was presumably caused by Shigella sonnei. He was originally admitted for suspected lung cancer. The clinical p...

INTRODUCTION Various causes of intractable hiccups have been reported; however, to the best of our knowledge, there are no previous reports of either intractable hiccups due to esophageal candidiasis in an immunocompetent adult or improvement following antifungal therapy. CASE PRESENTATION An 87-year-old man presented with intractable hiccups. Although the patient was immunocompetent, he used...
