We present a case involving a 74-year-old woman with cat scratch disease characterized by an enlarged and hard axillary lymph node as well as a palpable breast nodule mimicking a carcinoma. The lymph node and the breast nodule were excised. The pathologic examinations revealed granulomatous lymphadenitis with gram-negative bacilli and an intraductal papilloma. Antibiotic therapy (azithromycin) was prescribed and the patient's clinical evolution was excellent.

Infections caused by the Bartonella species are responsible for the human diseases collectively called 'bartonellosis'. The clinically important human infections are mostly caused by the three species (eg, B. bacilliformis, B. quintana and B. henselae ) of Bartonella out of the many progressively increasing identified species. Bartonella henselae transmitted by the arthropod vector, fleas, after cat bite is responsible for the rare multisystem cat scratch disease in humans. We present an extremely rare case of B...

Cat scratch disease (CSD) typically manifests as a febrile lymphadenopathy and is caused by a Bartonella henselae infection after contact with cats. This article describes the case of an atypical presentation of CSD in a 52-year-old patient with acute unilateral loss of vision and headache without fever or lymphadenopathy. Funduscopic examination showed an optic disc swelling and macular star exsudates, pathognomonic for infectious neuroretinitis. A Bartonella henselae infection was confirmed serologically...

Feline idiopathic head-and-neck dermatitis-also named feline idiopathic ulcerative dermatitis (IUD)-is considered as a rare skin disease of unknown origin. It is usually associated with a crusted, non-healing, self-induced ulcer occurring most commonly on the dorsal or lateral neck or between the scapula where self-grooming by scratching occurs. Usually, IUD is diagnosed after exclusion of other causes of pruritus. In feline medicine, self-induced alopecia is recognized as a behavioral disorder (abnormal repetitive behavior) due to excessive licking, which is an amplification of a normal maintenance behavior...

Cats and cat fleas (Ctenocephalides felis) are vectors of the zoonotic bacterial pathogens Bartonella henselae and Rickettsia felis, which are the causative agents of "cat scratch disease" and "cat flea typhus," respectively. In the surroundings of Vienna (Austria), we identified 11 (10.5%; n = 105) B. henselae-positive fleas originating from 8 cats (20.5%; n = 39). One flea was positive for R. felis. There should be high levels of awareness among veterinarians and animal keepers as to the handling of cats, especially if free roaming, stray, or feral...

We used real-time PCR to detect Bartonella henselae DNA in 7.9% (5/63) of blood specimens from seronegative patients in Japan suspected of having cat-scratch disease. The combined use of serologic tests and real-time PCR to analyze blood specimens is recommended for the prompt, noninvasive laboratory diagnosis of cat-scratch disease.

BACKGROUND: Qatar is one of the wealthiest and fastest growing economies in the world, experiencing a rapid increase in human and pet populations. Given the paucity of data on prophylactic measures against endo- and ectoparasites of pets in Qatar, as well as on the owners' awareness of zoonotic diseases, a questionnaire was conducted. METHODS: From July to November 2017, 150 multiple-choice questionnaires were administered to dog and/or cat owners who attended two veterinary clinics in Doha...

We report the case of a 53-year-old healthy man, presenting with confusion. The patient had been clinically diagnosed with cat-scratch disease (CSD) and prescribed a 10-day course of doxycycline orally. Approximately a week after he had completed the treatment, he was admitted to our department with confusion. Neurological examination revealed expressive dysphasia with no motor or sensory deficits. Cerebrospinal fluid (CSF) examination showed only increased content. Imaging with CT and MRI of the brain did not reveal any abnormalities, and funduscopy was normal...

BACKGROUND: Bartonella henselae is the causal agent of cat scratch disease in immunocompetent persons and bacterial angiomatosis in immunocompromised patients. In Chile, the prevalence of antibodies against B. henselae in healthy children and adolescents is 13.3%, in persons with occupational risk 60.5%, and in cats 85.6%. There are no published data regarding the seroprevalence in blood donors in our country, so determining if B. henselae is present in the blood of donors at the time of donation is very important, since this microorganism can survive up to 35 days in the red blood cells stored in a blood bank at 4 °C...

A healthy patient presented with painful skin lesions on the anterior surface of her legs. Erythema nodosum was diagnosed but all the usual causes were ruled out. The finding of bilateral enlarged axillary lymph nodes with necrosis and granulomas led to the diagnosis of Bartonella infection, an unusual cause of erythema nodosum. Imaging also revealed splenomegaly and small para-aortic lymph nodes. Up to one quarter of the patients with cat-scratch disease present atypically, a considerably higher prevalence than previously reported...

The lymphadenitis associated with cat-scratch disease (CSD) is often confused with neoplasms by a number of radiologists and clinicians, and consequently, unnecessary invasive procedures or surgeries are performed. In the present study, the contrast-enhanced computed tomography (CT) and magnetic resonance imaging (MRI) findings of 10 patients (6 men and 4 women) with clinically and pathologically confirmed lymphadenitis associated with CSD were retrospectively analyzed (CT in 3 patients, MRI in 6 patients, and CT and MRI in 1 patient) at The Second Affiliated Hospital of Zhejiang University School of Medicine (Hangzhou, China) between January 2007 and November 2014...

Hypercalcaemia occurs in many granulomatous diseases. Among them, sarcoidosis and tuberculosis are the most common causes. Other causes include berylliosis, coccidioidomycosis, histoplasmosis, Crohn's disease, silicone-induced granulomas, cat-scratch disease, Wegener's granulomatosis and Pneumocystis carinii pneumonia. Hypercalcaemia in granulomatous disease occurs as a consequence of dysregulated production of 1,25-(OH)2 D3 (calcitriol) by activated macrophages in granulomas. Hypercalcaemia in patients with Mycobacterium tuberculosis infection has been reported in 0%-28% of cases...

Cat scratch disease (CSD) is caused by Bartonella henselae, which mainly affects children. The cat is the reservoir. The laboratory diagnosis is based on the detection of antibodies by the Indirect Immunofluorescence (IFI) assay. The objective of this study was to analyze the serological evidence of B. henselae infection in pediatric patients that met the clinical/epidemiological criteria for suspected CSD. We studied 92 patients, who were categorized into four serological groups: 1) IgG (+)/IgM(+), 31,5% (n=29); 2) IgG (-)/IgM(+), 10,9% (n=10); 3) IgG (+)/IgM(-), 9,8% (n=9); 4) IgG (-)/IgM(-), 47,8% (n=44)...

Bartonella henselae infection is a frequent zoonosis from the domestic cat. It is presented with regional lymphadenitis in the majority of cases. Searching and characterization of lymph nodes by diagnostic imaging can be useful in the differential diagnosis approach, with a clear advantage, because it is a noninvasive method. Currently, new diagnostic imaging techniques improves the quality of screening and characterization of adenopathies, such is the case of PET/CT, which allows a better evaluation of hypermetabolic lymph nodes, without considering the individual growth of each lymph node...
