A 47-year-old stem cell transplant recipient with fever, cough and chest pain.

Infections and malignancies are among the most serious complications that follow organ or stem cell transplantation. They may have a mild course, and nonspecific and overlapping manifestations. The present article describes a case of symptomatic nodular pulmonary disease that complicated hematopoietic stem cell transplantation.

A 29-year-old man with hospital-acquired cavitary pneumonia.

Cavitary lung processes pose a formidable diagnostic challenge. Causes vary widely and include cavitary pneumonia, vasculitis and malignancy. In some cases, patient history and basic work-up may yield a diagnosis, but in others, an extensive work-up, including tissue biopsy, may be necessary to establish the cause.

A pneumonia that will not go away.

Pneumonia is a common diagnosis with significant morbidity and mortality. However, pneumonia is a commonly overdiagnosed entity, with many similar-appearing conditions. A young, previously healthy woman was misdiagnosed with a variety of respiratory tract infections over the course of five months before establishing the correct diagnosis - chronic eosinophilic pneumonia.

Mucormycosis in two community hospitals and the role of infectious disease consultation: a case series.

Background: Mucorales are ubiquitous filamentous fungi that can cause a devastating, invasive infection. This order has become an increasingly important pathogen during the last two decades, due to the dramatic increase in patients with predisposing factors. The aim of this retrospective study was to report the clinical characteristics, therapeutic options, and outcomes of patients diagnosed with mucormycosis in community hospitals in Amarillo, Texas, and to reflect on the role of infectious disease (ID) physicians in managing this potentially life-threatening problem.

Progressive disseminated histoplasmosis presenting with cachexia and hypercalcemia.

Histoplasmosis is a common endemic mycosis. The majority of infections involving this dimorphic fungus are asymptomatic. Manifestations in symptomatic patients are diverse, ranging from flu-like illness to a more serious disseminated disease.

Diagnosis and typing of systemic amyloidosis: The role of abdominal fat pad fine needle aspiration biopsy.

Introduction: Systemic amyloidosis (SA) has a broad nonspecific clinical presentation. Its diagnosis depends on identifying amyloid in tissues. Abdominal fat pad fine needle aspiration (FPFNA) has been suggested as a sensitive and specific test for diagnosing SA.

Comparison of ProEx C with p16INK4a and Ki-67 immunohistochemical staining of cell blocks prepared from residual liquid-based cervicovaginal material: a pilot study.

Background: Although liquid-based cervicovaginal cytology has high sensitivity for detecting dysplastic/malignant lesions, many pitfalls exist. Cell blocks can be prepared from residual liquid-based cervicovaginal material and used for immunohistochemistry. The aim of this study was to evaluate a new marker, ProEx C, on cell blocks and its ability to distinguish dysplastic/malignant lesions from morphologically abnormal but benign cells.

Primary testicular non-Hodgkin's lymphoma with atrial mass as an initial presentation of acquired immunodeficiency syndrome.

The association between human immunodeficiency virus HIV infection and the increased incidence of testicular tumors is a recent well-recognized phenomenon. Testicular tumors in the setting of HIV infection are most frequently of germ cell origin, less commonly lymphomas. We are presenting a unique case of testicular non-Hodgkin's B-cell lymphoma with associated atrial mass and mediastinal lymphadenopathy.
