[Eosinophilic enteritis with mucosal predominance and with a 4 years' course]

Area of Science:

• Gastroenterology
• Pathology

Background:

• Eosinophilic enteritis is a rare gastrointestinal disorder characterized by eosinophilic infiltration of the small intestine.
• Diagnosis can be challenging, particularly in cases presenting without peripheral eosinophilia.

Observation:

• A 42-year-old woman with a history of symptoms since childhood was diagnosed with eosinophilic enteritis.
• The patient did not exhibit peripheral eosinophilia, complicating the initial diagnostic process.

Findings:

• The case highlights the importance of considering eosinophilic enteritis even in the absence of elevated blood eosinophil counts.
• Clinical evolution following surgical intervention and key anatomical-clinical features of this rare entity are discussed.

Implications:

• This case expands the understanding of eosinophilic enteritis presentation and diagnostic considerations.
• It underscores the need for a comprehensive diagnostic approach in rare gastrointestinal diseases.
