Esophagitis Differential Diagnoses

Diagnostic Considerations
Always consider the possibility of systemic illness causing the esophageal manifestations (eg, AIDS, scleroderma, systemic lupus erythematosus, pemphigus). Always consider cardiac causes of chest discomfort and treat appropriately. If the diagnosis is unclear, admission for further evaluation is suggested. Do not misdiagnose cardiac chest pain as esophageal pain. Pain can be similar, particularly in elderly patients and women.

Conditions that may mimic symptoms of esophagitis include the following:
- Coronary artery disease
- Pericarditis
- Aortic aneurysm
- Nonulcer reflux disease
- Functional dyspepsia
- Stricture
Diagnosis of Candida esophagitis
Glycogenic acanthosis, reflux esophagitis, herpes esophagitis, and superficial spreading carcinoma may produce findings similar to those seen in Candida esophagitis. However, patients with glycogenic acanthosis are almost always older individuals who have no esophageal symptoms, and the mucosal nodules of glycogenic acanthosis tend to have a more rounded appearance, whereas the plaques of candidiasis are more linear.
Reflux esophagitis may also manifest as a nodular mucosa, but the nodules tend to be more poorly defined than those in candidiasis, and they are always contiguous with the gastroesophageal junction.
Occasionally, herpes esophagitis manifests as multiple plaquelike lesions in the esophagus, but this infection is more commonly associated with small superficial ulcers (see Diagnosis of Herpes Esophagitis, below). Superficial spreading carcinoma may also manifest as a nodular mucosa, but the nodules tend to have poorly defined borders, producing a confluent area of disease.
Undissolved effervescent particles and debris in the esophagus can be mistaken for the plaques of candidiasis. Thus, if infectious esophagitis is suggested clinically, a double-contrast study should initially be performed without the use of effervescent granules.
Diagnosis of herpes esophagitis
In the appropriate clinical setting, discrete superficial ulcers in the upper or mid esophagus without associated plaques should be highly suggestive of herpes esophagitis. In contrast, ulceration in Candida esophagitis almost invariably occurs on a background of extensive plaque formation. Candida and herpes esophagitis can often be diagnosed on double-contrast studies, obviating endoscopy. However, if radiographic findings are equivocal or if response to treatment is inadequate, endoscopy should be performed for a more definitive diagnosis.
Other causes of small superficial ulcers in the upper or mid esophagus include drug-induced esophagitis and Crohn disease. However, these entities usually can be differentiated from infectious esophagitis on the basis of the clinical history.
Diagnosis of cytomegalovirus esophagitis
Because herpetic ulcers rarely become as large as those of infectious esophagitis, the presence of 1 or more giant ulcers suggests the possibility of CMV esophagitis in patients with AIDS. However, in patients who are HIV positive, giant esophageal ulcers can also be caused by HIV (see Diagnosis of HIV Esophagitis below).
Other causes of giant esophageal ulcers include nasogastric intubation; endoscopic sclerotherapy; caustic injuries; and oral medications, such as nonsteroidal anti-inflammatory drugs, potassium chloride, and quinidine. However, the correct diagnosis can almost always be suggested on the basis of the clinical history.

Diagnosis of HIV esophagitis
Because most HIV ulcers are indistinguishable from CMV ulcers on the basis of the clinical and radiographic criteria, CMV esophagitis must be excluded by means of endoscopy before a diagnosis of HIV esophagitis can be established. Biopsy specimens, brushings, and/or viral cultures from the esophagus may be needed.
Differentiating between these infections is essential because most cases of HIV esophagitis dramatically respond to treatment with oral steroids, whereas CMV esophagitis is treated with relatively toxic antiviral agents such as ganciclovir (see Cytomegalovirus Esophagitis). Endoscopy is required for a definitive diagnosis before patients are treated.
Diagnosis of tuberculous esophagitis
Erosion of caseating nodes into the esophagus may result in the development of longitudinal or transverse sinus tracts or esophageal-airway fistulas. Similar tracts and fistulas may be seen in patients with radiation esophagitis, Crohn disease, trauma, or esophageal cancer. However, in these patients, the clinical history usually suggests the correct diagnosis.
Intrinsic tuberculosis is extremely rare and is characterized by mucosal plaques, ulcers, strictures, and fistulas. The development of dysphagia, coughing, or choking during swallowing suggests the possibility of esophageal involvement or fistula formation in a patient with tuberculosis.
Diagnosis of eosinophilic esophagitis
An increasingly recognized noninfectious form of esophagitis that may require differentiation from infectious esophagitis is eosinophilic esophagitis.[42] The majority of patients with this disorder present with intermittent difficulty swallowing solid food. On barium studies, eosinophilic esophagitis typically produces a series of concentric rings in the esophagus.
