Ecthyma gangrenosum is a rare skin infection classically associated with Pseudomonas aeruginosa. We performed a retrospective study of all cases diagnosed with ecthyma gangrenosum from 2004-2010 in a university hospital in Mexico (8 cases, 5 female patients and 3 male patients, ages between 4 months and 2 years). The most common risk factor for ecthyma gangrenosum is neutropenia in immunocompro...

OBJECTIVE To evaluate cross protection provided by administration of contagious ecthyma vaccines against strains of orf virus in goats. ANIMALS 126 Boer-Spanish crossbred goats (3 to 20 days old). PROCEDURES 85 goats were vaccinated with a goat-derived contagious ecthyma vaccine. Of these, 41 were challenge exposed with the virus strain for the contagious ecthyma vaccine, 40 were challenge ...

Molluscum contagiosum is a viral disease caused by a DNA poxvirus. The incubation period is usually two to seven weeks. Molluscum contagiosum virus I is the most prevalent. Molluscum contagiosum tends to be more common in children with a history of atopy. Lesions typically occur on the chest, arms, trunk, legs and face. The palms are spared. Molluscum contagiosum in healthy children and adults ...

We describe the histopathological characteristics of viral skin infections. Herpes simplex virus and varicella-zoster virus produce an intraepidermal vesicle with variable degrees of epithelial necrosis. Typical findings include keratinocytes with ballooned nuclei with a ground-glass appearance and giant multinucleated keratinocytes. In the endothelial cells of the dermal blood vessels, cytomeg...

INTRODUCTION Ecthyma gangrenosum is known as a characteristic lesion of Pseudomonas aeruginosa sepsis and is usually seen in immunocompromised patients. CASE PRESENTATION A previously healthy 63-year-old man was admitted with sloughy necrotic ulcerations of the skin over his sternum. He was afebrile and in good condition. A skin biopsy revealed ecthyma gangrenosum. Blood cultures remained ste...

Ecthyma gangrenosum is a rare and invasive cutaneous infection caused by Pseudomonas aeruginosa in the majority of cases, typically affecting immunocompromised patients, particularly those with neutropenia. We report a rare case of ecthyma gangrenosum in the absence of bacteraemia presenting as a solitary necrotic ulcer in a female patient with acute lymphoblastic leukaemia. A culture from the ...

BACKGROUND Although no scientific evidence has yet been published, it is widely understood that molluscum contagiosum tends to be more common and more intense in patients with atopic dermatitis. This lack of evidence led to the development of the present study. OBJECTIVES To evaluate the prevalence of the association between atopic dermatitis and molluscum contagiosum; to evaluate whether mol...

A eromonas hydrophila is a motile Gram-negative rod-shaped bacterium found in water sources that is typically pathogenic for fish. Although human beings are atypical hosts, A. hydrophila has been reported to cause a broad spectrum of disease syndromes (acute gastroenteritis, soft tissue infections, meningitis, peritonitis, sepsis) [1]. While initially believed to be an opportunistic organism on...

BACKGROUND While molluscum contagiosum is considered to be a frequently encountered disease, few data on its incidence are known. AIM The objective of this study was to describe the incidence of molluscum contagiosum in Dutch general practice and to assess the importance of venereal molluscum contagiosum. METHOD Data were taken from the national survey of morbidity and interventions in gene...
