Gastric ulcer perforation credited to paracoccidioidomycosis. Case report with autopsy / Úlcera gástrica perfurada por paracoccidioidomicose. Relato de caso com necropsia

Paracoccidioidomycosis or South American blastomycosis is an endemic disease that occurs predominantly in rural South America, caused by a termo-dimorphic fungus named Paracoccidioides brasiliensis. Its epidemiologic importance relates to its characteristics of transmissibility, susceptibility and morbidity, in addition to its high cost due to prolonged medical monitoring. It has a polymorfims in the description, explained by absent or nonspecific initial symptoms such as night sweats, weight loss or fever, and later symptoms according to its location of involvemente. The objective of this study was to report a case of uncommon presentation of this pathology. The case repot is the autopsy of a 74-year-old, white, female patient with predominant manifestation in the gastrointestinal tract originating from paracoccidioidomycosis, and complicated by one of the gastric ulcer perforation. This is an unusual presentation, and reports of gastric perforation credited to this agent were not found in the literature...

Paracoccidioidomicose ou blastomicose Sul Americana é uma enfermidade endêmica rural que ocorre predominantemente na América Latina, tendo como etiologia o fungo termodimórfico Paracoccidioides brasiliensis. Sua importância epidemiológica está nas características de transmissibilidade, suscetibilidade e morbidade dos casos, além de seu alto custo, devido ao acompanhamento médico prolongado. É uma doença cujos sintomas iniciais são ausentes ou inespecíficos como sudorese noturna, emagrecimento ou febre, diferente dos sintomas tardios, que acontecem conforme sua localização de acometimento, o que justifica o polimorfismo em sua descrição. O objetivo deste estudo foi relatar um caso de apresentação incomum dessa doença. Caso clínico com necrópsia de paciente do gênero feminino, 74 anos, branca, com manifestações clínicas predominantes no trato gastrintestinal provenientes de paracoccidioidomicose complicada pela perfuração de uma das úlceras gástricas. Trata-se de uma apresentação incomum e não foram encontrados relatos na literatura de perfuração de úlcera gástrica creditada a esse agente...

Gastric lesions in free-ranging black caimans (Melanosuchus niger) associated with Brevimulticaecum species.

The stomachs of 100 free-ranging black caimans (Melanosuchus niger Spix, 1825) from the Mamirauá Sustainable Development Reserve, Amazonas state, Brazil, were examined for parasitism and pathologic lesions. All animals were harvested for human consumption. Ascaridoid nematodes were found in 67 caimans and were identified as Brevimulticaecum sp. These parasites were associated with focally extensive, chronic gastric ulcers and formation of localized intramural granulomas containing nematodes. All caiman were in good nutritional condition, which suggests that effects of gastric nematodiasis on the crocodilian hosts were minimal at the time of slaughter.

Gastric perforation caused by Strongyloides stercoralis: a case report.

Strongyloidiasis is a parasitosis caused by the female nematode of the Strongyloides stercoralis. S. stercoralis causes a chronic infection that is asymptomatic in 50% of chronically infected patients, and it can also affect the stomach. Gastric involvement causes symptoms mostly mimicking gastritis. We report herein a case of gastric perforation in a 37-year-old woman, which was thought to be caused by S. stercoralis.

[Prepyloric ulcer and gastric schistosomiasis (report of a Tananarive case) (author's transl)]. / Ulcère pré-pylorique et bilharziose gastrique. A propos d'un cas observé à Tananarive.

The authors report on a case of a 37 years old man, from Madagascar, who had a gastric ulcer. The biopsies which were performed during endoscopy, gave evidence of ova of schistosoma inside the gastric mucosa. There was also a rectal and hepatic schistosomiasis (S. mansoni). Evolution was good with specific treatment (Niridazole). Short review of litterature, and discussion.

One patient was seen with Candida albicans infection in a gastric ulcer. Gastric biopsy was of value in the diagnosis. The patient responded well to Nistatin therapy.
