Anti-Neutrophil Cytoplasmic Antibodies: To Care or Not to Care.

Anti-neutrophil cytoplasmic antibodies (ANCA) associated vasculitis is a disease process with a wide range of presentations, from asymptomatic or minimally symptomatic disease with positive laboratory testing, to florid acute end-organ damage. Consensus has not been established as to the frequency and/or protocol by which ANCA testing should be repeated. We present the case of a 53-year-old woman who initially came to medical attention with persistent dyspnea and pulmonary infiltrates presumed to be due to acute exacerbation of chronic diastolic congestive heart failure.

The Sweet syndrome as a cutaneous manifestation of Crohn's disease.

Crohn's disease is an inflammatory bowel disease associated with many extraintestinal manifestations involving multiple organs, including the skin, eyes, liver, and joints. Classic Sweet's syndrome is a cutaneous manifestation of Crohn's disease, characterized by sudden onset of painful plaques or nodules of the skin associated with fever and neutrophilia. We present a case of classic Sweet's syndrome in a patient with well-controlled Crohn's disease.

A Case of IgG4-related Sclerosing Mesenteritis.

A 60-year-old African-American male presented to the emergency department with abdominal pain and distention associated with decreased appetite and weight loss for several weeks. A computed tomography (CT) scan of the abdomen and pelvis showed an 8 cm mesenteric mass with surrounding stranding and poorly defined borders. The patient underwent exploratory laparotomy and complete resection of the mass since the frozen section could not give a definite diagnosis.
