We herein report the histopathologic findings on a series of seven cases, six adults and one child, of CA. The most common findings include ulcers, areas of necrosis, mixed inflammatory infiltrates, and the presence of trophozoites, the invasive form of the parasite.

2022年5月26日 · Within the ulcer bed and exudate are numerous trophozoites of the protozoan pathogen, Entamoeba histolytica, which extend into the submucosa but not into the underlying muscular layer.

Cutaneous amebiasis was first described in 1892 by Nasse, 1 in a patient with an amoebic liver abscess that was complicated after drainage and caused extensive ulceration and necrosis of abdominal skin, subcutaneous tissue, and muscles. No evidence of the presence of trophozoites is mentioned in the original article, but Nasses's clinical ...

Cutaneous amebiasis arises when E. histolytica trophozoites from the bowel coming into contact with the skin and is usually found in the perineal, vulvar, and perianal areas. Infection of the diaper area is common in infants and children due to prolonged contact with infected stools.

2004年8月1日 · We herein report the histopathologic findings on a series of seven cases, six adults and one child, of CA. The most common findings include ulcers, areas of necrosis, mixed inflammatory infiltrates, and the presence of trophozoites, the invasive form of the parasite.

Our main focus was to draw clinical information to identify mechanisms by which amebae reach the skin, occurring in a relatively small percentage of infected individuals. The recorded data included age and sex of the patients, form of presentation, any associated illnesses and/or factors, and methods for diagnosis.

2018年5月9日 · We herein report the histopathologic findings on a series of seven cases, six adults and one child, of CA. The most common findings include ulcers, areas of necrosis, mixed inflammatory infiltrates, and the presence of trophozoites, the invasive form of the parasite.

2014年11月18日 · The most important feature of the pathology of human amebiasis is the greatly destructive nature of the anatomical lesions produced by the protozoan Entamoeba histolytica. Recent advances on the knowledge of biochemistry, immunology, cellular and molecular biology, and genetics of this parasite, added to the use of different in vitro, in vivo ...

Cutaneous amebiasis is a rarely reported clinical manifestation of E histolytica infection. In a review of 5,097 patients with invasive amebiasis admitted to a South African hospital, only
