Adenoviruses are a common cause of respiratory infection, pharyngitis, and conjunctivitis in infants and young children. They are known to cause hepatitis and liver failure in immunocompromised patients; they are a rare cause of hepatitis in immunocompetent patients and have been known to cause fulminant hepatic failure. We present a 23-month-old immunocompetent infant who presented with acute ...

Herpes zoster is a clinical syndrome which usually presents with a localized, vesicular rash in a dermatomal distribution. Cutaneous dissemination rarely occurs in immunocompetent patients, therefore little is known about the baseline demographic, clinical characteristics, management and outcome of these patients. Herein, we report a case of disseminated cutaneous herpes zoster in an immunocomp...

An immunocompetent patient recovering from gallstone-induced pancreatitis had to be readmitted due to abdominal pain, fever, and rapid deterioration. Computed tomography guided needle aspiration established the diagnosis of pancreatic necrosis infection; microbiological investigations revealed monoinfection with Lactobacillus paracasei subspecies tolerans. To our knowledge, this is the first de...

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...

Rhodococcus equi is a Gram-positive coccobacillus that can cause a variety of infections in humans, most commonly severe pneumonia.1-4 These infections typically occur in immunocompromised hosts, although, rarely, immunocompetent hosts may be affected as well.1-4 Nonequi Rhodococcus species have been implicated in human disease, albeit less commonly than R equi. We report a case of severe cavit...

Histoplasmosis is endemic to the Mississippi and Ohio River valley regions in the US. It usually affects patients with underlying immunodeficiency but can also be seen in immunocompetent hosts. Although gastrointestinal involvement is common in the setting of disseminated histoplasmosis, isolated gastrointestinal involvement is uncommon. We report a case of isolated pancreatic histoplasmosis in...

Roseomonas are a gram-negative bacteria species that have been isolated from environmental sources. Human Roseomonas infections typically occur in immunocompromised patients, most commonly as catheter-related bloodstream infections. However, Roseomonas infections are rarely reported in immunocompetent hosts. We report what we believe to be the first case in Korea of infectious spondylitis with ...

Introduction: Primary tuberculosis (TB) of the oropharynx and nasopharynx is an extremely rare form of extra-pulmonary TB in children. Primary tuberculosis occurs more likely secondary to pulmonary TB and is more common in immunocompromised patients.   Case Report: We reported the case of a young male presented with the symptoms of non-specific chronic adenotonsillitis, ...

BACKGROUND Reactivated cytomegalovirus (CMV) infection has been known to cause significant morbidity and mortality in immunocompromised patients. However, CMV disease rarely develops in immunocompetent patients, and reported cases often present with a mild, self-limiting course, without severe life-threatening sequelae. While the colon is the most common gastrointestinal site affected by CMV di...

Betapapillomavirus (betaPV) infections are often associated with squamous-cell carcinoma (SCC) and the prevalence of betaPV infections in (immunosuppressed) SCC patients is known to be high. The distribution and possible associated factors of betaPV infections in the general population, however, are largely unknown. To address this issue, betaPV infection was studied in 1405 SCC-free immunocomp...
