Pleomorphic hyalinizing angiectatic tumor of the vulva: literature review based on a rare presentation.

Pleomorphic hyalinizing angiectatic tumor (PHAT) of soft tissues is a rare, non-metastatic tumor of unknown etiology and uncertain behavior, which may recur locally. There are few reports on this condition, and due to the rarity of the disease, its lineage has not yet been fully elucidated. The present study aims to report the case of an unusual entity observed for the first time in vulval topography.

Accuracy of fine-needle aspiration of lymph nodes: A cancer center's experience.

Introduction: Lymph node fine needle aspiration (LN-FNA) is a minimally invasive method of evaluating lymphadenopathy. Nonetheless, its use is not widely accepted due to the lack of guidelines and a cytopathological categorisation that directly relates to management. We report our experience with LN FNA at a large Cancer Center in Latin America.

Giant lactating adenoma.

Lactating adenoma is a rare benign breast lesion that most often presents as a small (up to 3 cm), solid, well-circumscribed, solitary, painless, mobile, lobulated mass. The highest incidence occurs in primiparous women (20 to 40 years old) during the third trimester of pregnancy. However, in the rare case presented herein, in addition to its giant size (more than 10 centimeters on palpation), this lactating adenoma is distinctive due to the presence of multiple nodules, poorly defined ultrasonographic margins, worrisome radiologic features, growth since early pregnancy, presence of infarction and association with chronic mastitis.

Pulmonary artery aneurysm rupture.

Pulmonary artery aneurysm is a disorder of varying etiology and should be diagnosed early for appropriate interventions. A 45-year-old man was hospitalized for chest pain, dyspnea, cough, chills, diarrhea, and vomiting, which had started 3 weeks before admission. Physical examination indicated a reduced vesicular murmur in the right hemithorax.

Depression among patients with end-stage renal disease in hemodialysis.

Depression is frequent in end-stage renal disease (ESRD) and predicts mortality in dialysis patients. The aim of this study was to investigate the occurrence of depression among patients on hemodialysis. We conducted an observational cross-sectional study at two hemodialysis centres in the metropolitan area of Fortaleza, Ceará, Brazil, between September and October 2010.

Clinical presentation of leptospirosis: a retrospective study of 201 patients in a metropolitan city of Brazil.

Introduction: leptospirosis is a zoonosis of worldwide importance. The disease is endemic in Brazil. This study was conducted to describe the clinical and laboratory presentation of leptospirosis in a metropolitan city of Brazil.

Predictors of oliguric acute kidney injury in leptospirosis. A retrospective study on 196 consecutive patients.

Background: Acute kidney injury (AKI) occurs in 10 to 60% of patients with leptospirosis. The aim of this study is to investigate markers for oliguric AKI in leptospirosis.

Methods: A retrospective study was performed with 196 consecutive patients with leptospirosis-associated AKI.
