Ectopic CutaneousSchistosomiasis mansoniin the Sacral Region

Abstract

The authors report one case of late cutaneous Schistosomiasis mansoni in a biopsy of a skin lesion in the sacral region in a 51-year-old female living in Contagem, Minas Gerais. The patient was treated successfully with oxamniquine (Mansil®).

Expression of IFN‐γ, IL‐4, and IL‐17 in cutaneous schistosomal granuloma

“…In addition to the pathological changes associated with schistosomiasis infection, the present subjects demonstrated other lesions not directly linked to the parasitosis, including lesions of hyperkeratosis, irregular acanthosis, and papillomatosis. These findings are consistent with the observations of Raso et al …”

“…Cutaneous schistosomiasis is uncommon, but its clinical and histological features have been well defined. Clinically, these cutaneous lesions appear as soft, aggregated papules and slightly raised plaques with irregular contours, which are sometimes surrounded by small satellite papules . The clinical findings in the present study are consistent with these clinical data.…”

Ectopic Schistosoma mansoni Eggs Inside a Lipoma

“…1,2,5,7 Others have proposed the embolization of S. mansoni eggs through arteriovenous shunts opened by portal hypertension due to the hepatosplenic form of schistosomiasis. 3,6,8,[10][11][12] Clinically, the lesions appears as isolated or coalescent papules, with a herpetiform arrangement or zosteriform distribution. 1,4,5,8,10 In this case, no form of the S. mansoni worm was found, and the patient presents no symptoms suggesting a disease provoked by this parasite.…”

“…[2][3][4] Ectopic schistosomiasis has been reported in the cecal appendix, gallbladder, pancreas, peritoneum, urogenital system, central nervous system, myocardium, skin, esophagus, stomach, thyroid, and adrenal glands. [2][3][4][5][6][7][8][9][10][11][12] Ectopic lesions, to which eggs or worms may migrate and cause granulomas on the skin and extragenital or rectal mucosae are rare in every form of schistosomiasis, even in regions where parasitosis is highly endemic. 2,3,5,6 Identification of Schistosoma eggs at the anatomopathological examination is mandatory for diagnosis.…”

Anal polyp caused by Schistosoma mansoni

“…Cutaneous schistosomiasis caused by S. mansoni, is rare, and is preferably located in the thorax and abdomen 11,12 . It may be associated with intestinal, hepatointestinal and hepatosplenic schistosomiasis or with neuroschistosomiasis.…”
