Upper Gastrointestinal Manifestations of Crohn's Disease: Differential Diagnosis and Treatment of an Uncommon Presentation of Crohn's Disease.

Esophagogastroduodenoileal involvement of Crohn's disease (CD) is uncommon; less than 5% of adult patients will suffer from this condition, although this diagnosis is likely underestimated given the lack of routine evaluation of the upper gastrointestinal tract in the absence of symptoms. An interesting differential, including sarcoidosis, eosinophilic gastroenteritis, tuberculosis, and Brunner's gland hyperplasia, should be considered. The consequences of this diagnosis can have profound impacts on the military career of a soldier.

CMV Ileitis: To Treat or Not to Treat? Implications of Initiating Biologic Therapy for Concurrent Crohn's Disease.

Cytomegalovirus (CMV) enteritis is traditionally thought to be a self-limited infection in immunocompetent individuals. Consequently, current guidelines recommend against treating nonimmunocompromised patients with antiviral therapy. Conversely, recent data suggests that spontaneous resolution occurs less frequently than previously believed; furthermore, mortality rate in immunocompetent individuals is similar to that of the immunosuppressed.

Massive splenomegaly and lymphopenia: a unique case of obstructive shock.

We present a patient with intravascular large B-cell lymphoma (IVLBCL)-induced obstructive shock. This case represents a unique presentation of the disease, while highlighting the difficulty of establishing the diagnosis. Although there was a high clinical suspicion for a lymphomatous process, the obstructive shock component of the patient's presentation was perplexing.
