“…Lesions may persist for 1 to 3 weeks, while lymph node enlargement and overlying erythema can take several months to resolve completely. 1,2 Lymphadenopathy affects the lymph nodes draining the site of the cat scratch and is local in 85% to 90% of patients. 3 While local cervical, axillary, or inguinal lymphadenopathy is most common, more diffuse lymphadenopathy can also be seen in some patients.…”

“…3 Because cat-scratch disease is one of the most common causes of subacute or chronic lymphadenopathy in children, it should be considered in any pediatric patient with lymphadenopathy or fever of unknown origin. 2 Prognosis for most children with cat-scratch disease is excellent, with eventual spontaneous resolution in 90% to 95% of children. 1 A small minority of patients may require surgical drainage for persistent abscesses or removal of enlarged lymph nodes.…”

Cat-scratch disease is a bacterial infection caused by Bartonella henselae that most commonly presents with fever and subacute regional lymphadenopathy after being scratched by a domestic or feral cat. 1 It is one of the most common causes of subacute or chronic lymphadenopathy in children and should be considered in any pediatric patient presenting with lymphadenopathy or fever of unknown origin. 2 We present a case of a 7-year-old boy with a facial cutaneous lesion and submandibular lymphadenopathy after being scratched by a cat, presumptively diagnosed with cat-scratch disease. Case PresentationA 7-year-old boy presented to the outpatient pediatric clinic with a 1-week history of left-sided facial swelling (Figures 1-4).History. The patient had no significant past medical history. Three weeks prior, he presented to a local urgent care clinic with a vesicle on his left cheek and slightly swollen submandibular lymph node after being scratched by a kitten. His condition was diagnosed as lymphadenitis, and he was prescribed cephalexin. At the time, the lymphadenitis was attributed to recent filling of dental caries. Despite completing a 10-day course of cephalexin, he began to develop increased leftsided facial swelling without associated tenderness or erythema. The swollen area continued to enlarge over the next week. The patient had no associated symptoms of fever, eye discharge or redness, congestion, fatigue, sore throat, or change in appetite or activity. His mother denied prior history of lymphadenopathy or any change in color or drainage.

“…Los gatos son portadores sanos y por tanto reservorios de esta bacteria (9) . Se transmite vía vector, siendo la pulga Ctenocephalides felis responsable de la transmisión gato-gato, no así gato-humano (10) . No se han reportado casos de transmisión humano-humano (5) .…”

Cat scratch disease (CSD) is an infectious disease produced by Bartonella henselae. It typically causes fever, regional adenopathy, an inoculation zone papule and malaise. It is transmitted by a cat scratch or bite. Infrequently has atypical manifestations like neuroretinitis, which usually manifests as unilateral and painless decrease of visual acuity. We present a clinical case and review of the literature. A seven-year-old girl with malaise, fever and weight loss who iniciated blurred vision in superior hemifield of the left eye. Alterations concordant with neuroretinitis were seen in the fundus of the eye without other findings at physical examination. An infection by Bartonella henselae was objectified, making the diagnosis of CSD associated neuroretinitis. The pacient received antibiotic treatment achieving total clinical improvement. The diagnosis of CSD associated neuroretinitis is based on clinical criteria, useful to guide the etiologic study, and laboratory exams that allow to confirm it, being indirect inmunofluorescence and ELISA the most usedtest, for their high efficiency. Once the diagnosis is confirmed, the treatment is performed with bi-associated antibiotic therapy, being adjusted according to the patient’s age. Irreversible sequelae can be caused by CSD associated neuroretinitis, so it is recommended to treat it and maintain subsequent periodic controls.

Con el objetivo de determinar la frecuencia de casos seropositivos a Bartonella henselae en niños con adenitis regional atendidos en un hospital nacional del Perú, se realizó un estudio trasversal en 106 niños con adenitis regional mayor de 1 cm de diámetro, de aparición aguda, con tiempo de enfermedad mayor de cinco días, atendidos en el Instituto Nacional de Salud del Niño durante el año 2012. Se definió seropositividad para B. henselae mediante el examen de inmunofluorescencia indirecta, siendo positivos 86 niños (81,1%) con una mediana de edad de 7 años, rango de 5 a 11; en el análisis bivariado se encontraron como factores asociados, edad mayor de 5 años, antecedentes de fiebre, adenopatía mayor de 4 cm y reporte de contacto con gato. En conclusión, los niños con adenitis regional atendidos en este hospital de referencia nacional presentaron una frecuencia alta de serología positiva para B. henselae.
