Summary
Cat scratch disease, caused by Bartonella henselae, can present without swollen lymph nodes, manifesting as prolonged fever and liver/spleen lesions. This highlights its potential as a cause of fever of unknown origin, especially in Japan.
Area of Science:
- Infectious Diseases
- Pediatrics
- Hepatology
Background:
- Cat scratch disease (CSD) is typically associated with regional lymphadenopathy.
- Bartonella henselae is the primary causative agent of CSD.
Observation:
- Three pediatric patients presented with atypical CSD, exhibiting prolonged fever and back pain without lymphadenopathy.
- Two patients developed hepatosplenic granulomas, including hypoechoic lesions in the liver and spleen.
- One patient required a partial left hepatic lobectomy for a significant hepatic lesion.
Findings:
- All patients demonstrated elevated antibodies to Bartonella henselae.
- Bartonella henselae DNA was confirmed via polymerase chain reaction in tissue from the patient who underwent surgery.
- These findings indicate systemic Bartonella henselae infection.
Implications:
- Cat scratch disease should be considered in the differential diagnosis of fever of unknown origin, particularly when lymphadenopathy is absent.
- The prevalence of Bartonella henselae infections may be underestimated in Japan.
- Early recognition and diagnosis are crucial for appropriate management of atypical CSD presentations.

Immunodeficiency Diseases
Immunodeficiency disorders are conditions in which the immune system's ability to fight infectious disease and cancer is compromised or entirely absent. The immune system comprises a complex network of cells, tissues, and organs that work together to protect the body from potentially harmful invaders. When this system is deficient or not functioning properly, it leaves the body susceptible to infections, diseases, or other complications.

Rocky Mountain Spotted Fever
Rocky Mountain Spotted Fever (RMSF) is a severe tick-borne illness caused by Rickettsia rickettsii, a Gram-negative, coccobacillary bacterium. This pathogen is an obligate intracellular parasite, requiring a host cell for replication. Transmission occurs through the bite of an infected tick. In the United States, the most important vectors are Dermacentor variabilis (American dog tick) and Dermacentor andersoni (Rocky Mountain wood tick), though other tick species may also serve as vectors.
Chickenpox
Chickenpox is an acute, highly contagious disease caused by the varicella-zoster virus (VZV), a double-stranded DNA virus belonging to the Herpesviridae family. Its transmission occurs primarily through the inhalation of respiratory droplets or direct contact with vesicular fluid from skin lesions. The incubation period typically ranges from 10 to 21 days, during which the virus replicates and disseminates through sequential phases within the host. Although generally self-limiting in children,...
Cytomegalovirus Disease
Cytomegalovirus (CMV) disease is caused by human cytomegalovirus, a double-stranded DNA virus of the Herpesviridae family. While primary CMV infection is often asymptomatic in immunocompetent individuals, the virus can cause severe disease in neonates and immunocompromised patients. CMV is the most common cause of congenital viral infection in the United States, and a major pathogen in solid organ and hematopoietic stem cell transplant recipients.CMV is transmitted via bodily fluids, sexual...
Respiratory Syncytial Virus Disease
Human respiratory syncytial virus (RSV) is a widespread pathogen that primarily targets infants and young children but also poses a serious health risk to elderly and immunocompromised individuals. Belonging to the Pneumoviridae family, RSV is a negative-sense, single-stranded RNA virus within the Pneumovirus genus. Its global health burden is significant, with millions of cases annually resulting in hospitalizations and mortality, particularly in resource-limited settings. Although most...
Leishmaniasis
Leishmaniasis is a protozoal disease caused by species of the genus Leishmania and transmitted through the bite of infected female sandflies. The parasite exists in two principal morphological forms during its life cycle. A sandfly acquires intracellular amastigotes from an infected reservoir host, such as a dog. Within the sandfly, these forms differentiate into motile, flagellated promastigotes. During a subsequent blood meal, promastigotes are injected into the human host, where they...
