New records of Mansonella ozzardi: a parasite that is spreading from the state of Amazonas to previously uninfected areas of the state of Acre in the Purus River region.

Mansonella ozzardi infections are common in the riverside communities along the Solimões, Negro and Purus Rivers in the state of Amazonas (AM). However, little is known about the presence of this parasite in communities located in regions bordering AM and the state of Acre. The prevalence rate of M.

Rhinoscleroma causing severe bilateral nasal obstruction.

Rhinoscleroma is a chronic, infectious and granulomatous disease of the respiratory tract. There is often a delay in diagnosis due to unfamiliarity with the disease and also because culture is not always positive. We report a case in a 26-year-old woman with granular mass obstructing bilateral nasal cavities and causing breathing difficulty.

Lobomycosis: diagnosis and management of relapsed and multifocal lesions.

We report a case of lobomycosis in the left leg of a patient that had traveled to the endemic Brazilian Amazon region. After surgical resection of the lesion, there was relapse with local dissemination of the disease and the treatment was successfully performed by oral itraconazole and cryosurgery.

Acute conjunctivitis with episcleritis and anterior uveitis linked to adiaspiromycosis and freshwater sponges, Amazon region, Brazil, 2005.

We conducted an epidemiologic investigation of an outbreak of ocular disease among children to determine whether the disease was linked to Emmonsia sp., a rarely-reported fungus and an agent of adiaspiromycosis. Using an unmatched case-control study design, we compared case-patients with asymptomatic controls randomly selected from the population.

[Paracoccidioidomycosis at Brasilias university hospital].

Seventy-six paracoccidioidomycosis patients attended at the university hospital of Brasília from 1984 to 2005 were studied. 82.9% were male and the mean age was 42 years.

[Cutaneous protothecosis: case report].

A case of cutaneous protothecosis was reported in a 78-year-old man that was in treatment for pemphigus foliaceus and phaeohyphomycosis. He presented erythematous lesions which were infiltrated into his right leg. The diagnosis was made histopathologically and confirmed by culture, and the patient was successfully treated with itraconazole.

Case report of subcutaneous entomophthoromycosis with retroperitoneal invasion.

The authors describe a case of entomophthoromycosis in a previously healthy patient, who presented with an abscess in the right buttock. After surgical drainage it evolved into a retroperitoneal tumor. The patient improved clinically after resection of the mass and ketoconazole treatment.

[Human adiaspiromycosis: cicatricial lesions in mediastinal lymph nodes].

Chest roentgenogram of a sixty-year-old male patient, revealed a tumoral mass in the right lung, that was later demonstrated by transbronchial biopsy, to be a bronchogenic adenocarcinoma. There was no tomographic evidence of distant metastasis, however, in order to assess the mediastinal involvement for staging of the tumor, biopsies from the regional lymph nodes were obtained. Microscopic examination of the sample tissues failed to show any metastatic lesion, but, unexpectedly, revealed the presence of cicatricial granulomas in an advanced stage of fibrosis.

[Polycystic hydatidosis: casual finding of calcified hydatid cyst simulating mesenteric neoplasm].

A case of abdominal hydatidosis, without hepatic involvement, in a patient from the State of Acre is reported. The hydatid, already in degeneration and partially calcified, was discovered incidentally by a radiologic examination of the vertebral column, carried out for evaluating the state of an intervertebral disk prolapse. Although the images suggested a mesenteric tumor, attached to the intestinal wall, the finding of rostellar hooklets in the dense contents of the cyst, after surgical removal, revealed the parasitic nature of the lesion.
